1. The characteristic (Figure ; Appearance photograph of -100 M of E)
"It achieved necessary basic performance in the simple in the combination of the latest general technology" It is smallness, light weight, the multifunction and low-priced simple machine. However, with the power of the continuous flow mechanism and the pressure relieving mechanism, it is more applicable to the adult than to the newborn baby. In October, 1981, in the sale, in begun E-100, an exhalation-valve body was done with the external. In January, 1987, it was improved in -100 A of E and an exhalation-valve unit was stored in the main unit underside. -100 A of E were the Japanese specification which was produced in entrusted in America NMI Inc. (Newport Medical Instruments) but were integrated into the revised version of E-100i (the mind of international) in March, 1991 with production rationalization of the NMI Inc.. In E-100i, it abolished pressure cycle mode (Pressure cycle) with low frequency of library use, and it added "MO-DOSEREKUTA-" and an operation system was simplified. In June, 1997, it became -100 s of E, a mechanicaeration cable type manometer was changed into the digital bargraph display by the LED and a pressure trigger mechanism, too, was changed into the electronic type. An exhalation-valve control system, too, was improved and a response was improved. In April, 1998, -100 M of E and becoming ATC (the function to do a trigger level in the self-regulation), Time-Limited Demand Flow (the demand style additional structure to the spontaneous-respiration), Apnea A/CMV (the anaerosis back-up feature), AS (the pressure alarm level self-regulatory mechanism) were added. 2,350,000 yen of price

3. The explanation of the control circuit, the controlling mechanism
1) The outline of the controlling mechanism
As for the E-100 series, a new Mattick circuit is subtly changed in the version. As for the electric-control mechanism, a substantial change is accomplished in the times. In E-100i, "MAIKUROPUROTUSETUSA-" took charge only of the timing-control and the work drove one piece of Solenoid-controlled valve (the solenoid) of the intake valve only. It became -100 s of E and it got to take charge of the control of the exhalation-valve solenoid, the pressure trigger mechanism, the calculation of the setting air quantity of ventilation, the alarm mechanism, the bargraph display feature, too. It got to take charge of the work to do an alarm level and a trigger level more in the self-regulation in -100 M of E and to control an anaerosis back-up, too.
2) The characteristic of the mechanical mechanism
It uses a stock bag + continuous flow and an one way valve skillfully and the demand mechanism which can respond to the intake request irrespective of the inspiratory-phase and the expiratory-phase is the maximum characteristic to be shutting E-100 if multifunction. Moreover, the pressure pressure relief valve can do pressure relieving and pressure plateau ventilation.
3) The gas flow rate measurement
It isn't possible to measure. It became -100 s of E, the ventilation-meter (Voyager) of the turbine type was prepared by the option and the expiration air quantity of ventilation became able to be measured.
4) The intake valve
The output gas of Solenoid-controlled valve (the master valve) drives a new Mattick valve (the main flow valve and the continuing current selector valve). This is to improve power consumption reduction and reliability.
5) The expiration valve
It is a general balloon valve. The model before E-100i was driving a driving-pressure from the intake circuit and the pressure of the PEEP regulator with the circuit which weights a new Mattick type, but in -100 s of E, to hasten the reactivity of the exhalation-valve, it prepares an exhalation-valve solenoid and is changing intake circuit pressure and PEEP regulator pressure compulsorily. Moreover, PEEP regulator and an exhalation-valve design, too, were improved. As the result, the change of the driving-pressure became fast, the base pressure was more stable and the exhalation breathing resistance reduced.
4. The new Mattick circuit (Figure ; New Mattick schematic of -100 M of E) (Figure ; New Mattick schematic of -100 s of E)
1) Intake
It is O in the blender of the mechanicaeration cable type.2/ It mixes Air, after adjusting an oxygen concentration, it opens and shuts a master solenoid with the signal of MPU, and it opens and shuts an intake valve and generates intake dense fog. System gas opens an addition valve to the direct intake valve when pushing the manual button. Therefore, even if it was power failure time and equipment abnormality time, it was possible to ventilate a manual to E-100i. In -100 s of E, because it is controlling an exhalation-valve, too, by Solenoid-controlled valve, if the control board doesn't function, it isn't possible to do manual ventilation. The flow control (the intake current-adjustment) depends on the mechanical valve. The position of the control is taken as the electronic signal because there is a potentiometer on being coaxial about this control boiling.
2) The pressure plateau ventilation
The pressure plateau ventilation, too, can be used because a pressure pressure relief valve with mechanical method is made intake output with the internal organs.
3) The continuous flow mechanism (SPONTV1,SPONTV2)
When the intake demand by the patient exceeds a setting intake gas flow rate IMV and SIMV, CPAP spontaneous-respiration and active-ventilation among them, gas and fresh air in the stock bag from the continuous flow mechanism can be breathed in via the one way valve and the non-common use air-intake-valve. Gas for the spontaneous-respiration, becoming Time Limited Deand Flow, too, was prepared by -100 M of E. As for this, open intake gas is supplied to the degree of the trigger in the intake valve like the active-ventilation to the spontaneous-respiration. Because an exhalation-valve is closed only at the PEEP/CPAP pressure, it is relieved by the exhalation-valve if becoming any more pressure. Of course, the shortage of the intake gas flow rate can be sucked from the continuous flow mechanism. As for this feature, the airway pressure reduces a declining problem in case of intake of the spontaneous-respiration.
In the expiratory-phase, SPONTV1 and the SPONTV2 continuing current flow through breathing circuit from the one way valve and update gas in the patient circuit with fresh gas as the rinse style. SPONTV1 is 8LPM fixation in the continuous flow mechanism inside. It is possible to make SPONTV1 continuing current to be off with the switch of the surface in the left side. SPONTV2 controls a flow rate with the flow meter that external was done. It is possible to set in the range of 0-15LPM. Moreover, a solenoid for the intake outlet or the change whether or not to sense which with the proximal airway pressure tube, too, was added in the airway pressure. Because the patient circuit became complex about the proximal airway pressure monitor tube, this change switch was prepared to make support the patient circuit which doesn't use this. 無論、近位気道内圧"MONITA-TIYU-BUWO"使用"SURU"方"GA"感度"GAYOI"。
4) The pressure cycle mechanism
The mode solenoid and the "Jet venturi" mechanism don't exist after E-100i because a pressure cycle mode was E-100i and was abolished. In the pressure cycle (Pressure cycle) mode of -100 A of E, an intake gas flow rate is increased with gas in the stock bag in the jet venturi "Jet venturi" effect. Therefore, the actual intake gas flow rate becomes bigger than the set value. The intake gas flow rate as the patient circuit internal pressure rises falls to the set value. (It becomes 暫減 corrugation). In Time cycle, the main flow becomes intake gas just as it is because an intake gas flow rate increase mechanism is done at the bypass with the mode solenoid.
5) The exhalation-valve
In case of the expiration, it makes the pressure which was controlled with the PEEP adjusting-valve exhalation-valve output, but in case of intake, the intake gas pressure weights an exhalation-valve driving-pressure via one way valve 15 and E-100i closes an exhalation-valve. The exhaust system "MUFLLERS to be because it is drive-system response well 21" is provided. Of -100 s of E since then, it adds an intake solenoid valve and it instantly changes the pressure (the pressure and the inspiratory-pressure which was adjusted with the PEEP regulator) which depends on the exhalation-valve. It boiled in the one where it is difficult for the PEEP/CPAP regulator, too, to receive the change of the supply pressure and it was changed.
5. The control software
The explanation of the each function
1) The trigger formula
In E-100i, it adopted Light Gate type pressure trigger formula. This was detecting a trigger by the mechanical mechanism which takes the movement of the pin of the airway-pressure-meter by the optical senser. When moving the control of the trigger level, the optical senser which was provided inside the airway-pressure-meter is connected with the trigger level display arrow and changes. In -100 s of E, it added a proximal pressure monitor tube and it was changed into the electronic type which used a pressure transducer. The trigger sensitivity underwent influence even if it changed the setting of PEEP/CPAP as the result and passed away. Moreover, sensitivity and response, too, were improved and the work volume to the trigger reduced. When Time Limited Demand Flow is operating, it is locking a trigger so as not for there to be a trigger (in a maximum of 1.5 seconds) until the base airway pressure is stable so as not for AutoCycle to occur.
It is the quantity ventilation of usual time cycle but the maximum intake time is 5 seconds. It is possible to do the pressure plateau ventilation to have cut peak pressure using the pressure pressure relief valve, too. It becomes IMV if adding a continuous flow.
It became a variable-time method because 25% of expiratory-phase ends of the SIMV cycle were the fixed time method which is made a trigger window before E-100i but were changed into 100% since -100 s of E.
6. The operation system (Figure ; Operating panel figure of -100 M of E) (Figure ; Operating panel photograph of -100 M of E)
It sets a taking air quantity of ventilation in the product in intake flow rate "FLOW" and intake time "INSP.TIME". Because this product became displayed at the value of -100 s of E since then, to compute by it isn't necessary. Next, it is possible to use if setting the control of the breathing rate and the oxygen concentration and the control of mode "MODE". It controls the adjustment of PEEP and the control of pressure relief valve "RELIEF VALVE" if there is need. It sets a trigger level and an alarm level last. In -100 s of E, these setting can be instantly done with the presetting button. In -100 M of E, the alarm level can be done using AS and the trigger level can be done by the automatic setting using ATC.
A/C however, in the expiratory-phase, the gas of the continuous flow + stock bag can be freely breathed in. Therefore, it lowers the setting of a breathing rate only to single and it becomes IMV. SIMV mode however, it becomes IMV if doing a lot of continuous flows or setting trigger sensitivity low.
2) The pressure relieving ventilation
Of the mode which is being "DURE" however, it becomes pressure plateau ventilation when working "RELIEF VALVE". Now, it passes away with the ventilation of 従量 type (Volume control).
3) The continuous flow
If lacking in SPONTV18LPM), continuous flow SPONTV2 can be further added from the transversal flownmeter of the mixer.
ATC is the function to do best trigger sensitivity in the automatic setting by the abbreviation of Advanced Trigger Control. For the sensitivity to become low about 0.14cmH2O every time it senses a self trigger, trigger sensitivity is automatically changed (To the maximum-2cmH2O). When the trigger of the patient can not be detected for 15 seconds (being 32 seconds in the SPONT mode) in A/C and the SIMV mode, the sensitivity becomes high oppositely about 0.28cmH2O. As for the maximum sensitivity, the value of the table becomes the upper limit.
Way, it is recognized to do a self trigger when meeting a condition below.
(Table ; Maximum sensitivity in ATC)
(1) When the trigger interval is short more continuously three times than the following value
・Neonate 0.3sec.
・pediatric 0.4sec.
・Adult 0.8sec.
(2) When the I:E ratio deviates from the following value continuously three times
・Neonate I:E>5:1
・Pediatirc I:E>4:1
・Adult I:E>3:1
(3) Being higher than the baseline pressure with the latest trigger level (the absolute value) which was fixed by the mechanical internal process, it is and it bites. It is within 2cmH2O that the latest baseline pressure is the baseline pressure which was measured last time. This OBJ DO but to be a definition with baseline pressure the way of ( in the case ) the baseline pressure of which is however a measurement PEEP/CPAP level generally in it should become equal to the setting PEEP/CPAP level originally. to make a trigger performance be stable In other words, there is a problem in the process of fixing baseline pressure and it is in the condition which falls into the condition which raises up a self trigger.
(4) When the baseline pressure isn't stable for equal to or more than 0.06 seconds at the infant, the adult
(5) When inducing a trigger in the decline of the pressure which doesn't fill 100-mS 0.28cmH2O
5)AS(AutoーSet Alarm)
It does a high-pressure alarm and a low pressure alarm level in the self-regulation when pushing the AS button. Automatic setting is done based on the peak airway pressure at the time of the active-ventilation in twice of the pasts. At the adult, as for the high-pressure alarm value, the value of + 15cmH2O is stored in the inspiratory-pressure. The value of + 5cmH2O is stored at the newborn baby/the infant. But, the minimum value is 25cmH2O and 15cmH2O respectively.
6) The nebulizer
Nebulizer output by 8LPM is prepared. The intake gas flow rate increases only for 8LPM when making a nebulizer on. In -100 s of E, the part is reflected in the setting air quantity of ventilation calculated value, too.
7) Battery drive
The battery which was option handling became included as standard equipment of -100 s of E since then. It is possible to operate for about 6-8 hours by the full charging.
8) The notice
Because the graduation unit of FLOW is (changed into LPM since -100 s of E) L/sec. at the equipment before E-100i, don't confuse with the value of LPM which is used by the other resuscitator. It changes a few setting of the control and the switch which is only a little only and the ventilation form changes roughly. This is the versatility of this machine but a few setting mistakes and mistakes become a big mistake.
7. The monitor, the alarm function
1) The airway pressure
It is equipped with the alarm of the maximum airway pressure and the minimum airway pressure. In E-100i, it was detecting the movement of the pin of the airway-pressure-meter in the optical senser. This, too, was the mechanism to set by making both be connected with one control in the structure like the trigger mechanism. Of -100 s of E since then, using the pressure transducer, because it did, it became possible to make an electronic type by the automatic setting in One Button, too. Also, it became for both to have been able to be set independent, too. The alarm sounds when the airway pressure doesn't exceed a minimum airway pressure level by 15 seconds (or 30 seconds).
2) The intake time (INSP.TIME TOO LONG)
When the setting of intake time exceeds 50% of the CMV cycle time, intake ends compulsorily at 50%. Therefore, the I:E ratio doesn't reverse.
(3) Equipment's being mal-function
8. The display feature
In addition to lamp's lighting up with the alarm, there was not a display except the airway-pressure-meter, but it became -100 s of E and in E-100i, the setting air quantity of ventilation and the airway pressure got to put on by the numeral display.
9. The patient circuit composition, the humidifier (Figure ; Patient circuit adult and figure ; Patient circuit infant)
The F&P type is come equipped with. In -100 s of E, it uses the proximal pressure monitor tube not to have been using in -100 A of E, E-100i.
10. The daily maintenance
1) Breathing circuit, the exhalation-valve (Figure ; Exploded view of exhalation-valve : Fixing a diaphragm balloon on the cap with the screw and moreover forcing a cap into the exhalation-valve body and fixing it)
An exhalation-valve is sterilized every patient. It makes even if it is the same patient minimum and in the week, twice, it is sterilized in the wash. Specifically, when using a nebulizer, it attends. It makes the front of the construction dry up sufficiently.
2) The stock bag
It is not consumables but however, no matter why, when not using a continuous flow, "REZA-BA-BATUGU" always checks because it is the important functional part of this machine. It exchanges if necessary.
11. The regular inspection
The 3,000-hour use, or it makes minimum and its receiving regular inspection about once the year It overhauls within 12,000 hours.
12. The fault
1) It is necessary to compute to set a taking air quantity of ventilation. Also, the response of the trigger is bad. However, these were improved of -100 s of E since then. There was a problem which can not adjust an alarm level and a trigger level successfully, too, in E-100i before but this, too, was more improved in the becoming in -100 M of E.
2) That PSV isn't made is unsatisfaction as the present resuscitator but to say it may be cruel.
3) This is not a fault and is a merit but that Japanese manual is made is very good for it. It is the fulfillment and the correctness of the contents, the appropriateness, the ease to understand, however the special mention one of the Japanese translation. There is percentage of completion above English manual. Generally, there are many things in the manual of Japanese of the import equipment unclear of the meaning that Japanese to have translated literally and for it to have been mistranslated is only enumerated "TONDEMONAI". Unexpectedly, too, first-class product however, such a thing is well seen.
4) About ATC The possibility that the function to recognize a self trigger is better if making the trigger invalid when recognizing a self trigger if polished In other words, it is the possibility that it is possible to prevent a self trigger more effectively than changing trigger sensitivity and being made not to make the following trigger malfunction. Such a feature is called filtering algorithm and is practicalized in Drager "NADO". However, to require such a feature to the equipment of this class may be cruel.
1. The characteristic (Figure ; Appearance photograph of e500)
e500 is the best model of the NMI series which was done by the launch in April, 2002. The maximum intake gas flow rate which reaches 250LPM, too, and the quick response, the self-regulation feature of the PSV end-of-suction end recognition condition to be called FlexCycle and so on are a characteristic. Because the back work to use a bias style to support a newborn baby in e-200 as the continuous flow was used, PTV was incompatible. e500 got for the PTV support by the infant (20 ml of taking air quantities of ventilation -) to be possible with the accuracy improvement of the gas control technology. An exhalation-valve, too, was improved at the servo control. The simple, advanced function, the feature which is indispensable to the resuscitator in "NADO" today that a ventilation monitor is made of "GURATUHUIKUDEISUPURE-" where PCV and PRVC are made is compactly mediated between. 5,070,000 yen of price

3. The explanation of the control circuit, the controlling mechanism
1) The outline of the controlling mechanism
At the control board of the main unit, it is microcomputer Troller of 16 bits (MC68HC16Z1CFC16) , 16 MHz of frequencies are used. Intel 80486DX, 100 MHz, a DOS system are used for GDM (the graphic monitor).
In e500, the improvement of the flow control technology on the software which pioneered E-200 in the improvement of the hard ware, too, is pursued. the expectation feedback control ( pressure ventilation in case of control of the hill/Rhys "NIOKERU" It is example of "NADOGA" of ) (which does a bias style in the self-regulation to make pressure of PEEP/CPAP) of ( of the feature of the revision of the automatic leak of start-up speed self-regulatory mechanism ), (self-regulation) ) (of the end-of-suction end recognition condition of) FlexCycle ( (PSV) (be stable).
1) The characteristic of the mechanical mechanism
The intake servo valve was one but in e500, E-200 is using an independent servo valve for each of the oxygen, the air. It became for the response and the high peak rate of flow to have been able to be gotten as the result. It gets the PEEP/CPAP pressure which was stable with the exhalation-valve, too, getting to do a servo control and it is making an expiration work volume reduce.
3) The gas flow rate measurement
The side of intake is a heat ray type and the side of the expiration is a delta-pressure type.
4) The intake valve
Oxygen and the air are an independent servo valve.
5) The expiration valve
The control-gas which was adjusted with the servo valve is the mechanism which drives a diaphragm in the exhalation-valve block.
4. The new Mattick circuit (Figure ; New Mattick schematic of e500)
1) Intake gas
The control of the control of flow and the blend ratio is done with the flow control valve (the servo valve, Metering Valve) which was independent after decompressed respectively with the regulator about oxygen, the dense fog which was entered than the air plumbing. This valve was one but E-200 became for the peak with high flow rate to have been able to be more supported in being equipped to oxygen and air independent. These gases are the flow transducer of the supersonic transit type which measures a flow rate in the difference of the rate of propagation of the supersonic and are measuring a flow rate. As for this, the propagation time of the sound wave which propagates in fluid is the one to have used the nature that the speed of fluid changes and the difference in the propagation time among two supersonic sending sources becomes the flow rate of fluid.
2) Expiration gas
As for expiration gas, a flow rate is measured with the flow transducer of the delta-pressure type with a heating done with the heat exchanger after passing a filter. After that, it is released in the big worrying via the exhalation-valve. At the previous resuscitator, it often puts a flow transducer behind the exhalation-valve but it is often attaching to the recent equipment in front of the exhalation-valve. This is to absorb a pressure inclination by the flow rate resistance by the servo loop of the exhalation-valve. An exhalation-valve is controlled with the exhalation-valve drive gas which pressure was adjusted to in "WO" EXHALATION VSO SOLENOID VALVE. The pressure of this part, too, is monitored.
3) The safety-play
The purge style of 6-10LPM is provided from the proximal pressure monitor tube as the safety-play at the time of power off. Way, at the time of power on, it is the following of 0.05LPM. For safely, as for the proximal pressure, it is equipped with two pressure transducers. A crossover solenoid is prepared by the purpose of the time to have become one gas and the control gas of the equipment can be secured even if either gas is blocked off. It uses as the generalization, being as good in the servo valve as in the high performance aeroplane and a new Mattick circuit is simplified, but e500, too, doesn't leak out 0 the example and is simple.
5. The control software
The explanation of the each function
1) The trigger formula
Pressure trigger (-0.1-5.0cmH2O) or the float rigger (infant 0.1-2.0LPM, adult 0.6-2.0LPM) can be chosen.
The pressure ventilation or the quantity ventilation can be chosen by general A/C and the mode to be written.
The method which is called a variable-time method is used. It is the method which is the same as being generally employed in the resuscitator which is made in America.
At the previous resuscitator, the notation of CPAP was used in the meaning of the spontaneous-respiration mode and became the expression which causes misunderstanding but the expression of SPONT is used recently right. This mode means the spontaneous-respiration which used CPAP or PSV.
In the abbreviation of Volume Target Pressure Control/Volume Target Pressure Support, it is the meaning which is the same as the mode to be written with PRVC/VS in Servo300, Servo i. In the SIMV mode, an active-ventilation is given in VTPC and a spontaneous-respiration is given in VTPS. In the SPONT mode, it is ventilated in VTPS. At the time of this mode selection, the first time ventilation becomes either of 40% of the pressure limit or PEEP/CPAP pressure + 5cmH2O higher pressure. A ventilating-pressure is self-adjusted in the range of the pressure limit from either of 40% of the pressure limit or PEEP/CPAP pressure + 5cmH2O higher one. In other words, it is ventilated at the value which was computed from the pulmonary compliance for the taking air quantity of ventilation to become a set value. A variation every ventilation is limited to +/-6cmH2O. When the air quantity of ventilation can not be achieved even if it reaches a pressure limit, the alarm of Vol Target Not Met is done in the caution.
6) PS cycle off standard FlexCycle (Figure ; Sybernation diagram of PSV)
It names the function to do an end-of-suction end recognition condition (the cycle off standard) in PSV in the self-regulation FlexCycle. It is possible to command even if it is manual and it is possible to set in 5-55% of ranges of the highest value for expiratory flow. Self-regulation is self-adjusted in two elements of the rise of the pressure about the last years of the end-of-suction and breathing time constant. When attempting to make the lung of the patient the load of the resuscitator, it is possible to express in the resistance and the elasticity but these are called breathing time constant. It thinks that the details of FlexCycle are unclear, but that the value to have supported breathing time constant is decided when guessing from the control method of the conventional NMI Inc. and that the value is used for a cycle off standard. Even if the increased pressure, i.e. the overshoot in the end of the end-of-suction happens, PSV is compulsorily ended. After PSV beginning, until 0.2 seconds, it is in the increased pressure of + 6cmH2O in off the cycle, but since it, the with the passage of time standard value declines until 0.5 seconds and becomes + 3cmH2O since 0.5 seconds. (Figure ; It refers to Automatic cycle off explanation). In the self-regulation, 5-15% is chosen by the infant and 10-55% of values are chosen by the adult. PSV is the longest and is limited to 1.2 seconds by 2 seconds of adults, the infant.
7) The control of the hill/Rhys
It is possible to choose at the value of 1-19. On value itself of 1-19, the absolute meaning is the index which shows a relative degree, not being. For the details, it refers to the chapter of the learning type predictive control of E-200. Probably, it seems to be the mechanism which does the time constant and the gain of the feedback servo control in the self-regulation. Automation/hand 動 can be chosen if GDM (the graphic monitor) is attached. When not attached, it is automatically controlled. Incidentally, the concept is different from the control of Rhys time-out which goes in Evita and Servo.
8) The anaerosis back-up
6. The operation system (Figure ; Operating panel photograph)
1) The basics
Behind power on, it does the leak testing of the patient circuit. If checked in ME Muro, it may pass in this test. Next, it chooses a patient category. Next, it chooses a mode. After that, because it lights up that it is possible to do the making which is necessary it by "MOKU" which will go, it turns the knob of the each clause eyes and it adjusts a parameter. Next, it sets an alarm item (the expired volume per minute, the airway pressure).
2) The presetting
Before switching over a mode, beforehand, it is the function to enter beforehand the value which suited the mode.
After pushing the presetting button, it enters a desired mode and setting. The present mode indicater is as it lit up and a new mode is displayed in the blink. The ventilation that the current line breaks even if it operates a parameter is sustained just as it is. A presetting condition is canceled within 5 seconds if pressing no presetting again last or setting it. Presetting contents are reflected in the setting when choosing a new mode. Way, the user setup (the initial setting screen) can be entered when turning on while pushing this button.
3) The nebulizer
There is not a nebulizer feature.
4) Battery drive
The battery can operate for about 1.5 hours.
5) The back-up ventilation
It shifts to the back-up ventilation automatically when the low expired volume per minute alarm operates. It is automatically canceled when exceeding +10% of the low expired volume per minute alarm level. In the mode, in case of A/C, SIMV, the air changes per hour gets for 1. of the set value to be quintuple. (Doing 15 times of minimum, a maximum of 100 times) As for the other parameter, it is adaptable to the panel setting. In the SPONT mode, it is ventilated in PCV of 15cmH2O. As for the adult, the setting of 0.6 seconds of Ti=, 20 times of RR= is set in 1.0 seconds of Ti=, 12 times of RR=, the infant.
6) The anaerosis
There is not an anaerosis back-up but it enters back-up ventilation by the low expired volume per minute.
7. The monitor, the alarm function
1) The monitor
It puts on by the taking air quantity of ventilation, the expired volume per minute, the peak intake flow rate, the peak-expiratory-flow, the I:E ratio, total air changes per hour, the oxygen concentration, the intake time, the peak pressure, the plateau pressure, the mean-pressure, the base pressure, the "WO" numeral display. It displays an airway pressure by the liquid crystal bargraph.
2) The alarm
The expired volume per minute upper limit and the minimum, the airway pressure upper limit and the minimum, however, it is.
(3) Equipment's being mal-function
There is an alarm of the gas supply, being power failure, the equipment warning and so on.
8. The display feature (Figure ; Corrugated display example of graphic image 3 and figure ; Display example of graphic image loop)
The option function When equipped with GDM of the color display of 10.2 inches, in addition to 3 pressure and flow volume corrugations' being able to be monitored, the loop screen, too, can be displayed at the same time. The cycle off standard and the hill/Rhys can be set with the manual only when equipped with GDM.
9. The patient circuit composition, the humidifier (Figure ; Patient schematic of e500)
It comes equipped with the F&P type. It uses a proximal pressure monitor tube.
10. The daily maintenance
1) It exchanges a patient circuit according to the standard of the facilities.
2) The exhalation-valve filter
The exhalation-valve exchanges a filter if patient "TO" or the resistance becomes high when protected with the filter.
3) The expiration module (Figure ; Exhalation-valve module of e500)
In expiration filter use, as occasion demands, it does resolution, a wash, sterilization. The patient when not using a filter or it does resolution, a wash, sterilization as occasion demands fully. Fluothane Thirsk Lean is careful of the handling because he is a precision instrument.
4) The intake manifold
It does resolution, a wash, sterilization because it doesn't pollute to be general but the shutdown by the equipment caution, the malfunction in the supply of oxygen and the air, the high base pressure lasts, however, the intake manifold has the possibility of the pollution in the condition which doesn't use a filter when occurring.
11. The regular inspection
It exchanges parts in the gas supply unit to 1 or 3,000 hours by hour and it overhauls to 3 or 15,000 hours by hour.
12. The fault
1) That the resuscitator of NMI which began with E-100 was grown at the highly efficient resuscitator is very filled with deep emotion. (Good meaning however, bad meaning however,) as for E-100 around the early stages, with the atmosphere like the toy, the idea, the device and the creativity shrunk. Does it is in the reminiscent taste of the enthusiast that it cry over the way and e500, saying having become a cool machine?
2) To do the wonderful of the performance to have suppressed basics fast is the point which 10,000 admit but in the price range of the intermediate level machine, the rival machine which is excellent about the price performance is being crowded. What will the unique appeal point of e500 be to the 一般 user who doesn't have special contemplation?
3) "YOBOI" of supposing that the resolution of the image of GDM sees from the level of the present PC Necessary volume of information is displayed but there is not beauty of the screen. Moreover, because the edge of the monitor of GDM is broad, in the display for the smart PC, it gives a Dasai impression to the familiar eyes.
3) The artistry as the industrial design can not be felt to the operating panel of e500. Plainly twopenny -100 M of the most inexpensive E are rather more beautiful as the industrial design.
4) The structure of the exhalation-valve module is too complicated. The resolution construction is terrible.
