NIPPY 3+ Positive Pressure Ventilator
The Nippy 3+ 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 3+ may be 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 1.5 seconds and minimum of 0.7
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.
2
Alarms
Power Fail If the electrical power to the ventilator is interrupted, an audible
alarm will sound. This alarm will run for 5 minutes unless cancelled with the mute
button. Once cancelled the power fail alarm will not re-activate.
Low Internal Battery When running on its internal battery, the alarm will operate when
the battery is almost depleted
The user cannot replace this battery. Refer to qualified technical personnel for
battery replacement.
Low External Battery When running on an external battery, the alarm will operate
when the battery is almost depleted. Machines fitted with an internal battery will
automatically switch to internal battery power without alarming.
Low Pressure A pre-set low pressure alarm is provided. If the control pressure falls
to below 50% of the set IPAP level for 10 seconds an audible and visual alarm will
operate.
High Pressure A pre-set high-pressure alarm is provided. If the pressure rises above
120% of the working pressure, an audible and visual alarm will operate after a 2
second delay.
Breathing Circuit Disconnect A disconnect alarm is provided. This is
activated by analysis of the inspiratory and expiratory flow waveform. An audible
and visual alarm will operate.
Breathing Circuit Malfunction This alarm warns of a malfunction of the
exhale valve in the IPPV mode circuit.
High Flow alarm An adjustable alarm is provided to warn of excess
inspiratory flow. This is activated when the inspiratory flow exceeds the set high
flow alarm level for 5 seconds. An audible and visual alarm will operate.
Low Flow alarm An adjustable alarm is provided to warn of insufficient
inspiratory flow. This is activated when the inspiratory flow fails to achieve the
set low flow alarm level for 10 seconds. An audible and visual alarm will operate.
Fault The alarm may also be operated by an internal fault. In this case the fault will
be displayed on screen.
These alarms may be muted for approximately 2 minutes to allow for setting up
of the ventilator.
Low Internal Alarm/Memory Battery An intermittent alarm (short beep) with no
onscreen message indicates a depleted mains fail alarm battery. If the ventilator has
been stored for more than a few weeks the internal battery will self discharge. In this
case the alarm will stop after the battery has recharged.
The user cannot replace this battery. Refer to qualified technical personnel if the
alarm operates when the ventilator is in daily use.
3
Estimated Tidal Volume
The estimated tidal volume is a calculated value, based on time and calibrated flow
values. The constant leak through the breathing circuit exhalation port is subtracted
from this calculation to give a reasonably accurate estimation of tidal volume. The
estimated tidal volume is displayed above the bargraph display.
Inspiratory Trigger
The Nippy 3+ employs flow triggering, detecting the start of the patients inspiratory
effort when the flow rate exceeds the level set by the Inspiratory Trigger sensitivity.
Expiratory Trigger
The expiratory trigger is used in Pressure Support mode only. Towards the end of
inspiration, when the inspiratory flow rate drops to the baseline (standing flow
caused by exhale port leak) minus the expiratory trigger sensitivity the ventilator will
cycle into the expiratory phase.
The inspiratory and expiratory effort required to cycle the ventilator can be adjusted
via the Trigger option in the Menu.
For simplicity the trigger sensitivity is scaled 1 – 10, with 10 being the most difficult.
4
Intended Use
The Nippy 3+ is designed to augment ventilation in adults with acute or chronic type
2 respiratory failure.
Patients who suffer from nocturnal hypoventilation are chiefly those with failure of the
respiratory pump, though any concomitant lung disease is also deleterious. The
main groups of patients who develop this problem are: -
Patients with respiratory muscle weakness. E.g. diaphragm paresis, myopathies, old
polio, motor neurone disease.
Patients with skeletal deformity e.g. scoliosis, thoracoplasty
Improvement of ventilation during sleep by non-invasive techniques in these patients
will correct the diurnal abnormalities of blood gases.
Adjustment is carried out by medical staff. The patient only needs to fit the headset
and nasal mask and switch on the machine. Patients with special needs, such as
disabled or elderly persons, may require assistance when fitting the headset. The
medical staff would assess the level of assistance required.
The ventilator is placed by the bedside and plugged into the domestic electricity
supply.
Providing that a suitable socket outlet exists near the bed, no installation is required.
Nippy 3+ may be used to treat patients via:-
Tracheotomy
ET Tube
Full Face Mask
Nasal Mask / Nasal Pillows
IMPORTANT!
Batteries used for power fail back up must be kept in good condition and
fully charged at all times.
Nippy 3+ must be prescribed by, and used only under the supervision of a
qualified physician.

(or less for weak, frail patients). Set the EPAP to minimum (3 cm H2O).
CAUTION: Avoid starting off with the pressure too high.
7. Ensure that the back-up rate is set to a lower value than that observed when assessing
the patient.
8. The patient may now hold the mask to the face.
9. Allow the patient to get used to the mask. Then gradually increase the IPAP setting
until the patient feels comfortable and is being ventilated efficiently. 10 to 20cm H2O
will suit most patients.
10. If the inspiratory or expiratory trigger needs to be adjusted, select “Adjust trigger level”
from the menu and adjust to suit the patient.
11. Read the rate from the display (top of screen). This should match the value observed
when assessing the patient. If the rate has increased, make sure that the trigger is not
so sensitive that it is causing “self triggering”. It may be due to the patient’s anxiety at
trying a new treatment. Stay with the patient while he / she settles down. When the rate
has settled, set the Back-up to a value a few BPM below the patient’s rate. Allowance
should be made for a reduction in rate when the patient falls asleep.
12. Set EPAP if required. Then strap the mask/headset to the patient.
13. Set Up the alarms, as detailed in the “Setting Up the Alarms” section of this manual
Test the alarms as detailed in “Alarm Conditions and Tests” section of this

Setting Up the Alarms
Automatic Setting
For convenience, the high and low flow alarms may be set automatically. Varying
leak or the patient getting out of synch with the ventilator may disrupt the
measurement process. Therefore it is vital that the alarms are tested after setting up.
Low Flow Alarm
Press and hold the Low Flow Alarm button
The ventilator will read the peak flow, the inspiratory baseline or leak flow and set the
low flow alarm to the mid point between these two values.
This setting may be further adjusted manually if required.
Test the alarm as detailed in “Alarm Conditions and Tests” section of this
manual.
High Flow Alarm
Press and hold the High Flow Alarm button
The ventilator will read the peak flow and set the high flow alarm to this value plus
30% or 20 l/min, whichever is greater.
This setting may be further adjusted manually if required.
Test the alarm as detailed in “Alarm Conditions and Tests” section of this
manual.
Warning!
The auto set facility is not infallible. Varying leak can cause erroneous readings.
The settings must be verified and the alarm function tested. If the alarm settings are not
correct or the alarms do not operate when tested, proceed to the manual set up.
Manual Setting
Low Flow Alarm:-
Note the peak flow reading. This is the patient’s peak inspiratory flow.
Disconnect the breathing circuit at the mask or tracheotomy and occlude the end (do
not obstruct the exhale port). Note the peak flow reading. This is the leak flow.
Reconnect the breathing circuit.
Set the Lo alarm to a value approximately half way between the leak flow and the
peak inspiratory flow.
Test the alarm as detailed in “Alarm Conditions and Tests” section of this
manual.
If the patient is being treated via a nasal mask, this alarm is not required and may be
set to minimum.
High Flow Alarm:-
Note the peak flow reading. This is the patient’s peak inspiratory flow.
Disconnect the breathing circuit at the mask or tracheotomy end. Note the peak flow
reading. This is the disconnected flow.
Set the Hi alarm to a value a little higher than the peak inspiratory flow. This must be
lower than the disconnected flow. Allow for an increase in flow if the patient takes a
deep breath.
Test the alarm as detailed in “Alarm Conditions and Tests” section of this

Alarm Conditions/Tests
Test the alarms prior to use or daily for machines that are in constant use.
Before testing alarms, ensure that the alarm is not muted. To cancel the Mute,
press and hold the mute switch until a beep is heard (2 seconds).
High Flow Alarm
If the inspiratory flow exceeds the high alarm value, the alarm will be activated
accompanied by the on-screen, high flow alarm message.
To Test Disconnect the breathing circuit at the patient outlet port and allow the
flow to exceed the set alarm value. The alarm will be activated after a delay of 5
seconds, accompanied by the on-screen, high flow alarm message.
Disconnect Alarm
If the breathing circuit becomes disconnected, the alarm will be activated.
To Test Switch on the ventilator and cancel the Mute. Disconnect the breathing
circuit at the patient outlet port. The High Flow alarm will be activated after a delay of
5 seconds and will be replaced by the disconnect alarm after 10 seconds,
accompanied by the on-screen disconnect alarm message.
Low Flow Alarm
The low flow alarm warns of insufficient inspiratory flow. This could be caused by a
blockage in the patients’ airway or breathing circuit. The resulting drop in flow will
activate the alarm.
To Test Switch on the ventilator and cancel the Mute. Occlude the outlet and
wait 10 seconds. The alarm will sound, accompanied by the low flow alarm message
and the flow display will turn red.
Power Fail Alarm
If both mains and internal power to the Nippy 3+ fails, the alarm will operate and
continue for approx. 5 minutes. Press the mute button to silence the alarm.

switch off the mains power at the wall socket. The screen will go blank after a few
seconds and the alarm will sound. Press the mute switch or restore the power and
re-start the ventilator to silence.
Machines fitted with internal battery – Power fail alarm will only operate if the internal
battery is completely discharged and the mains fails. The only way to test it is to run
the ventilator on battery power until the battery is exhausted and the power fails.
High Pressure Alarm
If the airway pressure exceeds 120% of the IPAP setting for more than 2 seconds,
the alarm will sound and the pressure display will turn red.
It is not possible for the user to test this function.

ventilator. The machine MUST be referred to suitably qualified technical
personnel for investigation/repair.
24
Running the Nippy 3+ on Battery Power
Nippy 3+ may be powered from the mains, external battery or internal battery.
When running on mains, the ventilator will recharge its own internal and/or
external battery. Charge time is normally around 8 to 11 hours, per battery,
depending on the ventilator settings.
Batteries will also be charged when the Nippy is connected to the mains supply
but not running. Leave connected to the mains supply in between periods of use
to keep the batteries charged or to recharge ready for the next use.
When an external battery is connected to a machine, which has an internal
battery, each battery is charged to approximately 90%, starting with the internal
one. Then both batteries are fully charged starting with the internal one. When
the battery(s) are charged, the charge will terminate and the battery will be
monitored to maintain its charge.
NOTE: Basic models, not fitted with the internal battery have no reserve power
unless an external battery is connected.
The ventilator will select its power source, according to the power available, in
the following sequence:-
1. – Mains Electricity
2. - External Battery (if connected)
3. – Internal Battery (if fitted)
In order to save battery power, the ventilator will always run on mains electricity
if it is present.
If the mains fails or is not connected, the ventilator will select external battery as
the next choice. The external battery, if present, will always be run flat before the
internal battery is selected.
If there is no external battery, the ventilator will switch to its internal battery.
If there is no internal battery the ventilator will shut down and alarm.
Battery Run Times
Battery run times are dependent on the ventilator settings and the amount of
leak. High pressures and /or high breath rates use power and therefore shorten
run times. Large leaks use power and shorten run times.
The expected run time can be displayed on screen. Double press the SET
button to display a bar graph of run time. The time for each battery connected
will be calculated, according to the ventilator settings, and shown on the screen.
25
The run time may be as long as 12 hours for low values of CPAP with only
moderate leak, or as short as 4 hours for Pressure Support at maximum
pressure with quite severe leaks. Battery run times will typically be 20% more in
IPPV mode because of the absence of the exhale port leak.
Run times will be shortened by higher breath rates and/or higher EPAP levels.

When the battery is depleted an alarm will sound, accompanied by an on screen
message, “Battery Power Running Low”
When battery power reaches a critical level, the alarm will change to a
continuous tone and the on-screen message will change to “Battery Power
Exhausted. About to switch off. Connect to Mains Power Now”
After auto power off, the constant alarm will continue until the Mute is pressed.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can be estimated using the equation
applicable to the frequency of the transmitter, where P is the maximum output power rating of the transmitter in watts (W).
Note 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects, and people.
