9.9.6 Cautionary Notices
1. GAS SUPPLY PRESSURE
This equipment may be damaged if the gas supply pressure is too high. The
ventilator must only be connected to gas pipeline supply lines that are fi tted with
pressure relief valves that limit the supply pressure to less than 7bar/101.5psi.
2. HIGH FREQUENCY SURGICAL EQUIPMENT
The ventilator may be adversely affected by the operation of equipment such
as high-frequency surgical (diathermy) equipment, defi brillators or short-wave
therapy equipment in the vicinity.
3. BATTERY LIFE
To preserve battery life, never store the ventilator with its battery discharged.
Do not store or use the ventilator in close proximity to heat sources of any kind.
4. POWER FAILURE
In the event of a mains electrical power failure when the ventilator is running
from its internal battery, do not remove the mains plug from the mains supply
as this would prevent the immediate resumption of normal operation when the
mains power is restored.
5. ELECTROMAGNETIC INTERFERENCE
Excessive electronic noise caused by poorly regulated devices may interfere
with the proper functioning of the ventilator. To avoid this, do not connect the
ventilator to the same mains supply outlet into which an electrocautery unit is
connected.
6. EXHAUST GAS
The driving gas is discharged through the port on the rear panel of the
ventilator. This port must be completely free of any obstruction and should have
nothing connected to it. The exhaust gas is oxygen or MED AIR and does not
contaminate the environment.
7 BELLOWS EXHAUST
A negative or positive pressure applied to the EXHAUST port of the bellows
assembly results in positive pressure in the patient breathing system. The
scavenging system must therefore not generate more than 5cmH
2
O positive
or negative pressure when connected to the ventilator. The use of an AGSS to
EN 740:1999 is recommended. Do not connect a PEEP valve to the EXHAUST
