Along with the contents of the shipping carton you will require the
following items to enable you to undertake the pre-use functional
check:
[1] Full breathing air or medical grade oxygen cylinder.
[2] Air or oxygen regulator with a 50 PSI outlet and the correct DISS or
quick connector for the gas being used. The regulator must be
able to deliver an output flowrate of >120 L/min at no less than
45 PSI (3.1 Bar).
[3] Calibrated Test Lung.
Having connected the supply hose to the regulator, turn on the gas
supply. Using a mild soap solution, spray the input connection to the
resuscitator to check for leaks. If any leak is present, tighten the
connection “by hand” (Do not use a wrench) and re-test.
Once no leaks are found, connect the test lung to the 15/22mm patient
connector on the resuscitator. If the leak cannot be stopped, check and
replace the sealing “O” ring on the hose connection to the resuscitator. If
the leak persists, replace the hose.
The following features can be individually tested during the Pre-use
Functional Check:
[1] Peak Airway Pressure and Audible Alarm.
[2] Ventilation Frequency and Tidal Volume.
[3] Manual Ventilation.
[4] Demand Valve Function and Automatic Circuit Shut Off.
[5] Bleed Flow.
The supply hose provided is attached to the oxygen inlet on the rear of
the resuscitator and is tightened “finger tight” (fig 1).
The use of excessive force in tightening the supply hose
may damage the seal and /or thread.
The facemask is attached to the patient connection port by simply
pushing the mask onto the 22mm taper.

The ®has a Manually Actuated,
Automatic Ventilation Override Button (Manual Button) with a 20 second delay
to automatic cycling re-start to assist in the timing of ventilations in conjunction
with external cardiac compressions.
By using the Manual Button”, the operation of the ventilator can be easily
timed with the chest compressions so as to avoid the potential problem of
the aspiration of stomach contents due to gastric distension which may
occur if overlap of chest compression and inflation occurs. (It has been
shown in some studies that, in patients that are intubated, this overlap of
compression and inflation may increase cardiac output without the danger
of gastric distension.) The flowrate provided is equivalent to the preset
automatic flowrate.

1. If no respiratory effort is observed, position yourself above the
patient’s head. Turn on the gas supply.
2. Allow the device to cycle once and then apply the face mask over
the patients mouth and nose.The thumb and index fingers are used
to hold the mask to the face while the remaining three fingers of
each hand are placed along the angle of the jaw. A tilt action is used
to hyperextend the neck and move the jaw forward. This helps
displace the tongue away from the back of the throat and
maintains an open airway.
3. If manual Ventilation is to be used depress the manual button and
observe the rise of the patient’s chest. Release the button when
chest rise is adequate.
4. If the patient’s chest does not rise or gas escapes around the mask
or the pressure relief system (c) operates (fig 3), reposition the
patients head and adjust your hand position to obtain an effective
mask seal and an open airway.
5. Monitor the patient’s skin, nailbed and lip colour
6. If mask indicates signs of vomitus, remove immediately and clear
the airway. Ensure the mask and valve are free from obstruction.
Restart ventilation immediately after clearing airway. (See also 2.4).
7. Continue ventilation at an appropriate rate until relieved or until
spontaneous breathing returns.
1. If you are commencing automatic ventilation immediately, follow
steps 1 -2 and 4 - 7 above.
2. Closely observe the patient’s chest movements. If there is any leak
from around the mask or any obstruction in the patients airway
(blow off valve will operate) reposition patients head and adjust
mask and hand position to ensure a good airway and mask to face
seal.
If the patient is intubated (or if the patient is to be intubated
following mask ventilation), remove the face mask from the
22mm connector and attach the device onto the 15mm En-
dotracheal tube connector.

Should the patient vomit into the mask during resuscitation the
following steps should be followed to clear the foreign material:
1. Remove the mask from the patient’s face and clear any foreign
material from the patients airway. Depress the manual button
or allow the resuscitator to cycle automatically for a few breaths
to clear the mask and valve of foreign material.
2. If depressing the manual button repeatedly or automatically
cycling the resuscitator does not clear the foreign material from the
patient valve,turn the selector to the OFF position, remove the
facemask and unscrew patient valve swivel housing (e) from the
resuscitator body being careful to ensure that the diaphragm is
retained (Fig.3).
3. Shake out any foreign material from the resuscitator, diaphragm,
face mask and patient valve swivel housing.
4. Reassemble the facemask, patient valve and diaphragm and
attach to the resuscitator.

Should the patient commence spotaneous breathing at a flowrate of
greater than 30 lpm for more than 1 second the ®will
sense the patient’s inspiratory effort and will stop cycling automatically
allowing the patient to “De- mand Breathe”at their own rate and volume
on 100% oxygen (if connected to an oxygen supply). If they cease
spontaneous breathing the ventilator will recommense automatic
cycling after a delay of 5 - 8 seconds (depending on the depth of the
patients previous respiration) without intervention by the rescuer.
®
The ®is a pneumatically
powered, time/volume cycled ventilatory resuscitator with the added
feature of a Manually Actuated, Automatic Ventilation Override Button
(Manual Button) to allow the operator to control the ventilations manually at
a rate and volume they desire. The ventilator allows the breathing patient to
“Demand Breathe”through the device. Their inspiratory effort causes the
automatic cycling to cease. Should they stop breathing the ventilator will
automatically restart cycling in the setting selected.
A 2 litre per minute constant “BLEED FLOW”is provided to ensure a positive
remains in the mask throughout the ventilation cycle to decrease the risk
of entraining potentially toxic atmospheric air into the mask.
The “pneumatic logic circuit”can be run on either approved, compressed,
breathing air or medical oxygen. The unit is self-contained and only
requires its attachment to a regulated oxygen or air supply (as specified) for
immediate use.

To ensure proper operation of the resuscitator regular inspection and
checking of the resuscitator and accessories for correct function should
be undertaken by a responsible member of staff on a routine basis. This
check is to ensure that all of the accessories and resuscitator
components are present, the air or oxygen cylinder is full and that the
resuscitator is in working order.
Regulator working pressure, suction (if equipped), and ventilator limiting
pressures should be checked at least every six months, and more
frequently in high use applications. Units with test pressures outside of
the ranges listed in the product specifications should not be used. The
product is not designed for field disassembly or service outside that
indicated in this manual. Any malfunctioning units should be returned to
