Demand Valve and Demand Valve Resuscitator - User Manual
1. Introduction
1.1. Introduction
O-Two oxygen powered Demand Valve provides trained individuals
with a safe and eective means of delivering 100% oxygen to
spontaneously breathing patients in respiratory distress, at the
flow rate demand by the patient.
O-Two oxygen powered Demand Valve Resuscitator provides a
fast, simple and eective means to ventilate the non-breathing
patient and to deliver 100% oxygen to spontaneously breathing

2. Gas Supply
2.1. Gas Supply Connections
The O-Two Demand Valve and Demand Valve Resuscitator are
designed to operate on an input pressure of 50 PSI of compressed
medical oxygen from either a cylinder or piped-in system.
The inlet fitting on the Demand Valve and Demand Valve
Resuscitator is a standard 9/16” DISS fitting.
3. Operating Procedure
3.1. Demand Breathing
The O-Two Demand Valve and Demand Valve Resuscitator
are equipped with a Demand System enabling spontaneously
breathing patients to demand oxygen.
An inspiratory eort by the patient will activate the demand valve
and oxygen will flow to the patient at a rate and volume in line
with their inspiratory eort.
3.2. Manual Resuscitation (01DV2000 only)
The O-Two Demand Valve Resuscitator (01DV2000) has been
fitted with a Manual Button to allow manual ventilation of the non-
breathing or respiratory distressed patient.
By using the manual button, the operation of the resuscitator can
be easily timed with chest compressions during CPR. This will
avoid the potential problem of the aspiration of stomach contents
due to gastric distension which may occur if overlap of chest
compression and ventilation occurs. (In patients that are intubated
this overlap of compression and ventilation may increase cardiac
output without the danger of gastric distension.)
WARNING
At all times during resuscitation the rise and fall of the patients’
chest should be monitored to ensure adequate ventilation.

3.3. Operating Instructions
1. Ensure that the Demand Valve/ Regulator connection is
secured and no leaks present.
2. Turn the cylinder hand wheel counter clockwise to the ON
position (at least one full turn).
3. Ensure that the regulator contents gauge reads at least 500
psi. If not, replace with a full cylinder.
4. Attach the Universal Facemask to the Demand Valve outlet.
5. Place the mask on the patient’s face, covering both the nose
and mouth and hold the mask on his/her face with a light
pressure. The sound of gas flowing should be heard with
patient’s inspiratory eorts.
6. Should manual ventilation is required for the non-breathing or
respiratory distressed patient, simply press the Manual Button.
7. Ensure that the cylinder is turned OFF after each use.
Note: Demand Valves and Demand Valve Resuscitators are
considered critical devices, and their components considered
critical components. Only those individuals trained in Cardio-
Pulmonary Resuscitation and operation of oxygen-powered
resuscitators should use this equipment. Thoroughly review the
instruction manual before use.

4. Servicing
4.1. Routine Maintenance
WARNING
The O-Two Demand Valve and Demand Valve Resuscitator
are designed to provide respiratory support in all emergency
situations. Failure to follow the maintenance and inspection
routine could result in incorrect operation of the resuscitator.
To ensure proper operation of the Demand Valve and Demand
Valve Resuscitator, regular inspection and checking of the demand
valve and accessories for correct function should be undertaken
by a responsible member of sta on a regular basis, and it is
recommended that a service record be maintained for each unit.
This check is to ensure that all of the accessories and demand
valve components are present, the oxygen cylinder is full and that
the demand valve is in working order.
MAINTENANCE
Resuscitation parameters should be checked at least every six
months, and more frequently in high use applications. Units
with test parameters outside of the ranges listed in the product
specifications should not be used. O-Two Demand Valve are not
designed for field disassembly or service outside that indicated
in this manual. Any malfunctioning units should be returned to
the manufacturer or an Authorized O-Two Medical Technologies
Dealer. Unauthorized repairs will nullify the product warranty.

4.2. Cleaning and Disinfection
Routine cleaning and/or disinfection of the O-Two Demand Valve
and Demand Valve Resuscitator should be undertaken after each
patient use to maintain the equipment in a clean condition.
WARNING
Do not immerse the demand valve into cleaning solution or
disinfectant.
Discontinue to use and discard the face mask, the patient valve and
the diaphragm should discoloration or deterioration be observed.

Cleaning / Disinfection Procedure
1. Operate the manual button to blow out any contaminant from
the patient valve (01DV2000 only).
2. Ensure that the cylinder is turned o (completely clockwise)
and bleed any remaining gas out of the system by depressing
the manual ventilation button (01DV2000 only).
3. Remove the facemask from the Demand Valve (Resuscitator),
and then disconnect the unit from the regulator. This is
accomplished by counter-clockwise turning of the connection
nut at the regulator end of the hose. A wrench may be required.
4. Unscrew patient valve (A) from the unit body being careful to
ensure that the diaphragm (B) is retained (Fig1).
5. Remove the diaphragm and anti-entrainment ring (C) from
the patient valve swivel housing and wash these components
thoroughly in a mild soap solution;
6. Disinfect the face mask, patient valve and diaphragm using
commonly available cold chemical disinfecting solutions.
Rinse thoroughly with water after disinfection.
7. Sterilization, if required, may be achieved by other methods
compatible with the materials of manufacture of these
components including Ethylene Oxide Gas and Cidex.
8. The demand valve body (D) and gas supply hose can be wiped
over with a soft cloth and mild soap solution.
9. Dry all components thoroughly.
10. Re-assemble and check performance.
