8. Check the condition of the resuscitation masks. Ensure that they fit the Demand Resuscitator, that they are free from damage, and the cuffs are soft and pliable.
5.0 OPERATIONAL CHECK-OUT It is recommended that the OXY-VIVA 3 undergo the following simple functional tests to ensure that the unit is in readiness for use in an emergency. In addition to these tests the OXY-VIVA 3 should be placed on a preventative maintenance schedule which should include the tests detailed in section 8 of this manual.
9. Turn off the cylinder valve (clockwise) and place the keywheel in the case. Depressurise the unit by turning on the therapy flow control until the flow stops. Turn off the therapy flow control.
1 Tighten the oxygen cylinder in the yoke, making sure that the Bodok seal is in good condition and is in position (see 6.1, Cylinder Supply). Turn on the oxygen cylinder valve (anticlockwise) to ensure that no leaks exist (see 8.1) and that adequate contents are registered on the gauge.
The lid can now be closed and the OXY-VIVA is ready for immediate application should an emergency arise. 6.0 EQUIPMENT USE
2. The suction trap jar must be located in the housing provided, and connected to the venturi outlet.
6.1 Oxygen Supply
3. Check that the suction, attachment operates by turning the ‘SUCTION’ control ‘ON’, and confirm that suction is generated at the suction outlet of the trap jar.
The OXY-VIVA 3 has two oxygen supply inlets, a pin indexed yoke inlet for connection to oxygen cylinders and an auxiliary inlet/outlet sleeve indexed system (SIS) inlet for connection to a regulated 400 kPa external supply source.
4. Ensure that the Demand Resuscitator functions when the cylinder valve is open and the actuating button is pressed. When released, the plunger must return fully to the”OFF” position and completely shut off the gas flow. Block off the mask connection on the Demand Resuscitator and press the manual ventilation button.The pressure relief valve should open and gas should be heard venting to the atmosphere.
Cylinder Supply To fit a “C” size cylinder to an OXY-VIVA 3 first check that the Bodok seal is fitted to the pin indexed yoke connection and that the yoke wing screw is backed off. Remove any protective cover on the cylinder valve outlet. Crack the cylinder by briefly opening then closing the cylinder valve.
5. Check that the oxygen therapy attachment functions by turning the “THERAPY” control “ON” and confirm that gas flows.
Slide the cylinder into the frame at the base of the case. Locate the pin index holes on the cylinder valve with the corresponding pins on the yoke. Secure the cylinder valve in position by tightening the yoke wing screw.
6. Check that both airways are present and held securely in their clips.
Fit the keywheel to the cylinder valve and slowly open (anticlockwise). Ensure that the cylinder valve has made a leaktight seal and the cylinder pressure registers on the contents gauge. Close the cylinder valve and release pressure from the unit by turning ON therapy flow control until the pressure gauge
7. Check that the cylinder keywheel and yoke plug are securely attached to the case by their chains. 5

USE ON A NON BREATHING PATIENT
reads zero. Turn OFF therapy flow control. Leave cylinder fitted and turned off until it is required for use.
1. Turn on the oxygen cylinder valve The keywheel is located inside the case. Turn anticlockwise. Open the valve slowly and fully. Check the contents gauge for adequate supply.
Auxiliary Inlet/Outlet Supply This inlet allows the OXY-VIVA 3 to be used in a fixed location when a regulated external supply of oxygen is available, thus leaving the cylinder supply for use when portability is required. To connect to a regulated supply,the pin indexed yoke must be blocked off. This can be done by closing the cylinder valve, or by using a blanking plug secured in the pin indexed yoke. A length of oxygen hose with sleeve indexed hand wheels can be used to connect the OXY-VIVA 3 to the regulated supply source (connect the OXY-VIVA 3 end first, then the regulated supply end to prevent whipping of hose).
2. Clear the patient’s mouth and throat, use suction if required. Insert airway if necessary. 3. Tilt the head back, lift jaw. Place support under shoulders if necessary. 4. Attach the mask to the Demand Resuscitator. Select the child or adult size mask as necessary. 5. Apply the mask firmly to the patient’s face. Maintain an airtight seal over the nose and mouth.
6.2 Demand Resuscitator - General Description With the oxygen supply turned on, there will be no flow from the Demand Resuscitator until either the manual ventilation button is depressed or the patient inhales. A very slight inhalation effort produces an oxygen flow. The oxygen flow varies according to the inhalation effort and stops flowing during exhalation. An integral part of the Demand Resuscitator is an exhalation or non-rebreathing diaphragm and patient valve which allows gases from the lungs to be expelled during exhalation.
6. Press the manual ventilation button on the Demand Resuscitator until the chest rises - then release. Wait until the lungs deflate, then repeat the operation continuously. 7. When the patient begins to breathe, stop pressing the manual ventilation button. Keep the mask on the face. The patient will automatically receive 100% oxygen with each breath on demand.
To resuscitate a non-breathing patient the Demand Resuscitator has been designed to supply oxygen to the patient’s lungs by means of a mask or endotracheal tube. When the manual ventilation button is depressed, oxygen will flow and inflate the lungs.
CAUTION: Hazards of Overinflation. Overinflation of the lungs can occur if an excessive tidal volume is delivered, particularly in the case of children and when an endotracheal tube is in place. Inflation of the stomach can occur if an excessive tidal volume is delivered or if inflation is performed in the presence of a partially obstructed airway. If the stomach becomes distended, check the airway again but do not try to empty the stomach.
When the manual ventilation button is released the gases are passively expelled from the lungs via the exhalation diaphragm and patient valve. 6

5. If necessary, empty the reservoir jar during use to prevent overfilling.
USE ON A BREATHING PATIENT Turn on the oxygen cylinder valve.
Important Turn suction ‘OFF’ after use to prevent oxygen cylinder depletion.
The keywheel is located inside the case. Turn anti clockwise. Open the valve slowly and fully. Check the contents gauge for adequate supply. Attach the child or adult mask to the Demand Resuscitator
Trouble Shooting When suction is turned on, there is no aspiration of fluids.
Apply the mask firmly over the nose and mouth ensuring an airtight seal.When the patient breathes, the resuscitator will automatically supply 100% oxygen.
1. Check that the jar is tight. 2. Check that there is no blockage in the suction tubing.
NOTE Operation of the suction attachment uses oxygen. When suction is in use the suction attachment would empty a full “C” size cylinder (approximate contents 400 litres) in approximately 8 minutes.
If breathing stops,immediately proceed from Step under “Patient not breathing”.
NOTE The demand Resuscitator, when delivering a tidal volume of 600 ml, 12 times a minute to a patient, would deplete a “C” size cylinder (contents approximately 400 litres) in approximately 45 minutes.
6.4 THERAPY ATTACHMENT
6.3 SUCTION ATTACHMENT
When necessary oxygen therapy can be used. To use the oxygen therapy attachment:
To ensure clear airways before or during resuscitation, suction may be applied via the flexible suction tubing and catheter or handpiece when necessary.
1. Connect one end of the therapy tubing to the therapy outlet under the ON/OFF lever. 2. Connect the other end of the therapy tubing to the therapy mask.
1. Ensure that the suction collection jar is connected to the suction venturi under the ON/OFF lever.
3. Turn the ’Therapy’ control to ‘ON’.
2. Connect the suction tubing to the collection jar.
4. Fit the therapy mask to the patient’s face and form an effective seal. The elastic bands should pass just above and below the ears and the soft metal strip should be bent over the nose to form a seal.
3. Fit the suction handpiece or catheter to the suction tubing. 4. Turn the “Suction” control to “ON. This produces a continuous vacuum in the plastic reservoir jar and enables blood and other fluids to be sucked from airways.
5. The oxygen concentration delivered to the patient depends on the particular mask used, see specification section of manual.
