NIPPY Positive Pressure Ventilator
The Nippy jnr+ is a pressure controlled, positive pressure ventilator. It compresses
ambient air and delivers it to the patient through a close fitting nasal mask or a
tracheotomy. The output pressure, timing and alarms can be adjusted by controls on
the fascia panel. The Pressure, estimated Tidal Volume, Rate and all settings are
displayed on a colour LCD(Liquid Crystal Display) screen.
The screen can be set to dim after a pre-set time (accessed via the user preferences
in the main menu). To restore the display, press any button once.
The basic ventilator settings can be achieved using the four buttons to the left of the
display. The four buttons to the right of the display adjust the alarms and provide
access to more advanced features and adjustments (accessed via a menu).
For greater safety and convenience the Nippy jnr+ is equipped with an internal
battery. The ventilator is capable of recharging both the internal battery and an
external battery when running from the mains electrical supply.
There are 4 modes of ventilation:-
CPAP
(Continuous Positive Airway Pressure) Constant positive
pressure is applied via the mask. No respiratory support is
given in this mode.
Pressure Support
IPAP (Inspiratory positive airway pressure) and EPAP
(Expiratory positive airway pressure) are set by the
physician. The ventilator augments the patient’s
spontaneous breathing. Ti is limited to half of the back-up
period, up to a maximum of 1.2 seconds and minimum of 0.5
seconds.
If the patient’s breathing rate falls to the back-up rate, a
timed breath (Ti back-up) is initiated at the back-up rate.
Pressure Control
IPAP, EPAP and Ti are set by the physician. A timed
inspiration is cycled by the patients inspiratory effort.
Adjustable back-up rate takes over in the absence of
inspiratory trigger.
IPPV
IPAP and Ti are set by the physician. A timed inspiration is
cycled by the patient’s inspiratory effort. Patient exhales to
atmosphere via an exhale valve fitted in the breathing circuit.
EPAP is not used in this mode. Adjustable back-up rate
takes over in the absence of inspiratory trigger.
