NIP Nasal(VPAP II ST),VPAP III STA
The ResMed Inc. which was born in Australia in 1989 is the company the specialty of which is the treatment machine of the sleep apnea.
As NIV became popular finally, ResMed Inc. was transformed into the global corporation.
The Japanese specification of VPAP II ST was called NIP nasal but it was supplied together with the mask of the Japanese specification.
After that, it made VPAP II VPAP III in the model change.
It is reduced to the weight after a max-flow is increased and a forgiveness to the leak, and the performance and the operability that the trigger and the cycle setting can be changed, and so on, are improved.
3 models are in VPAP III and VPAP III STA is the series strongest model.
In any case, it features small light weight and it is light-weight more fairly than the competitor's products, too.

1) The outline
It isn't therefore published at all to the details of the mechanism.
The number of rotations of the blower is constant and adjusts an intake gas flow rate in the relieving quantity in the valve, but in ResMed, it changes the number of rotations of the motor and BiPAP adjusts an intake gas flow rate.
In this method, it is uneasy about being behind in the response in by the moment of inertia of the drive-system but behind seems quite excellent than there is not an inferior according to the company data.
But, regrettably, these daters aren't made public.
The feature to control in the sensitivity by making "MASUKURI-KU" in a pair in VPAP III and revising a baseline
automatically was added. It names this Vsync.
The setting contents can not be changed into NIP Nasal if there is not special controller UCU1 in it but the setting change is possible only at the main unit if VPAP II ST is stored in the back screen.
In other words, the patient can operate only power ON/OFF and a delay timer.
Because 5, 10, the slow ventilating-pressure OBJ DO and to break for 15 minutes rise to the set-pressure when pushing a delay timer, the pressure which the patient receives can be reduced.
NIP Nasal uses special controller UCU1 to change setting (Figure ; NIP Nasal special use controller
: Using and setting a menu key and an option key).
Main unit only however, in VPAP II, it is possible to do a setting change when accessing a setting screen.
The setting screen can be accessed when making a power on while pushing three keys of the right (Figure ; Sunset to setting screen of VPAP II
Next, it chooses a setting item in order using the MENU¢¤ key.
To change a set value, it pushes OPTION¢¤ key and the value, ON/OFF, "NADOWO" type in.
To use by the home, the setting must be locked to prevent an accident.
To lock, it chooses PATIENT MODE in MENU, and it presses OPTION¢ and it enters YES.
It presses OPTION¢ again, it enters and it fixes YES because it asks again with ARE YOU SURE.
A monitoring and setting become easier when VPAP III STA uses a special remote control but it can operate them even if it is not.
The basic operation is the same as VPAP II approximately and it chooses a setting item in order using the MENU¢¤ key (the arrow at the top and the bottom of the black).
To change a set value, it pushes OPTION¢¤ (green and orange) key and the value, ON/OFF, "NADOWO" type in.
It is possible to set in Rhys time (Min, 150-900msec), Ti control, i.e. least intake time (Tmin) and maximum intake time (Tmax), too, (Figure ; Explanation of Tmin and Tmax
The cycle time and the trigger sensitivity, too, can be set to 3 steps (Figure ; Setting of trigger sensitivity and setting of a cycle
When the synchronization with the patient doesn't work out, first, it attempts to control a mask fitting.
Moreover, "MASUKURI-KU" decreases when changing the shape of the mask and using band (chin strap) and sometimes solves, too.
The synchronous insufficiency with the expiration can be optimized when setting Maximum IPAP time (the longest IPAP time) to the appropriate value.
5. The monitor, the alarm
The air changes per hour, the taking air quantity of ventilation, the amount of
leak, the airway pressure can be displayed in MENU. There is not an alarm
It displays measurement intake time, the condition of the cycle, the condition, the measurement I:E ratio of the trigger and so on when pushing the key of QUICK VIEW.
There are a low pressure and high pressure alarm, a low expired volume per minute, Mask Off, mask worse, to be power failure, "NADONO" alarm.
6. The maintenance
It checks a mask and a tube daily and it cleans and it sterilizes them. It exchanges an
air filter every 6 months.
7. The fault
1) It is easy for the leak in the mask to influence operation when comparing with BiPAP in VPAP II. However,
this was improved in VPAP III.
2) It is passive about the mechanism and the dater elucidation. It isn't
providing enough information for the dealer.
