WARNINGS
Please Read Carefully and Fully Understand
Smoking, naked flames or other sources of ignition MUST NOT be
permitted near the equipment whether in use or in storage.
Ensure that the yoke clamp is firmly tightened and that there is no risk of
leakage before use. Leakage is a potential source of explosion.
DO NOT use oil or grease when maintaining the equipment.
DO NOT drop or mishandle the cylinder.
Cylinders must be stored at temperatures below 40°C.
TURN OFF cylinders when not in use.
USE ONLY brass or non-spark producing cylinder keys.
There is an increased risk of fire or explosion when oxygen is used in
inflammable or explosive atmospheres and extra care must be taken.
SPECIAL GUIDANCE
be used by personnel who have received adequate
Resuscitation (CPR) and the correct use of this
1.
The resuscitator MUST ONLY
training in Cardio Pulmonary
resuscitator apparatus.
2.
If ventilation is not achieved with the resuscitator, Expired Air Resuscitation (EAR)
should be used, and the airway re-checked.
3.
Over-inflation can occur, especially in children, if inflation is prolonged, sustained, where an
endotracheal tube is in situ, or as a direct result of an inadequate airway.
4.
Throughout resuscitation continuously monitor the casualty's pulse, pallor and pupils.
Frequently monitor the cylinder contents gauge. When children under 20kg require
resuscitation, operate the unit by gently depressing the manual trigger whilst watching
the chest rise and fall. DO NOT prolong or sustain trigger operation because overinflation may occur in extreme circumstances.
5.
If too large a face mask is used for spontaneously breathing children, the dead air
space will be excessive, which will adversely affect the performance of the unit.
6.
The resuscitator may be used in toxic atmospheres, provided the operator is wearing
suitable respiratory protective equipment.
DISCLAIMER:
Failure to comply with these instructions or misuse of the apparatus may result in death, injury or
material damage and invalidate any resulting warranty or insurance claims.

MARS OXYGEN
MARS can ventilate one casualty whilst
providing oxygen therapy to another
casualty.
Set for resuscitator: control
module, hose, patient valve,
regulator and masks.
At maximum adult setting, the system will
support one ventilated and one oxygen
therapy casualty for a period of 23
minutes when used with a 540 litre
cylinder.
1. INTRODUCTION
1.1
GENERAL
The 100% oxygen provided by MARS
improves the quality of resuscitation and
provides treatment to patients with
specific ailments including Carbon
Monoxide poisoning and decompression
sickness.
The MARS Oxygen Resuscitator is an
automatic gas powered time cycled
system, with patient trigger and manual
override.
The unit provides medical
oxygen for artificial respiratory ventilation
and a breathing-on-demand. The system
permits conscious patients to establish
their own respiratory pattern.
All procedures given in this manual have
been based on current UK first aid
practices. However, the user's training
and experience may vary from the
information provided but the operating
principles of the apparatus remains the
same.
The apparatus is classified as a Child/
Adult resuscitator for the normal range of
body masses from 20 to 60kg
respectively. The CPR setting, however,
may be used for heavier body masses,
where appropriate.
The MARS Oxygen Resuscitator
conforms to the requirements of BS 6850.
It is CE approved and meets the essential
requirements of the European Medical
Devices Directive.
The unit monitors patient breathing and
automatically shuts-off artificial ventilation
when spontaneous ventilation occurs,
while continuing to provide oxygen
therapy. The system also covers the
reverse situation, where, should the
respiratory rate drop below the pre-set
level, the unit automatically starts artificial
ventilation.
Once the operator has established an
effective seal between the patient's face
and mask, the unit is ideally suited for
resuscitation in a toxic environment,
because the system is totally sealed from
the external environment.
The resuscitator's audible alarm sounds
when there is an airway blockage or the
casualty's lungs become over inflated.
The
audible
alarm
operates
at
approximately 45 centimetres of water
pressure with any excess pressure being
automatically `dumped' by the system.
This feature protects the casualty from
over-inflation of the lungs or inadequate
ventilation due to a blocked airway.
