Puritan Bennett 540™ Ventilator User’s Manual
WARNING
Environment (Cont’d):
•
If the room temperature where the device is operated is greater than 95 °F (35 °C) , the flow supplied at
the device outlet may exceed 106 °F (41 °C). This may lead to undesirable side effects for the patient. To
avoid injury to the patient move the patient and the ventilator to a cooler location. For more
information, contact Puritan Bennett.
•
The default setting for altitude compensation is YES. Altitude compensation should always be set to
YES for accurate volume delivery calculations at all elevations.
•
To avoid a fire hazard, keep matches, lighted cigarettes, and all other sources of ignition (such as
flammable anesthetics and/or heaters) away from the ventilator and oxygen hoses.
•
If the ambient temperature is above 104 °F (40 °C), the battery's thermal cut-off circuit may prevent the
battery from recharging fully—even if the INTERNAL BAT charging indicator indicates the battery is
completely recharged.
•
Regularly check the cleanliness of the air inlet filter located on the rear of the ventilator. If necessary,
replace the filter before the recommended replacement period is over (see chapter
8, “Routine
Maintenance” ). This is particularly important when the ventilator is installed on a wheelchair, because
environmental conditions may cause the filter to become dirty more rapidly.
•
Handle the ventilator with care during and after use, particularly when room temperatures are high.
Some ventilator surfaces may become hot, even if safety specifications are not exceeded.
Electrical Power Supplies:
•
Never connect your ventilator to an electrical outlet controlled by a wall switch because the power may
be inadvertently turned off.
•
For the AC (“mains”) power cable to be properly secured, the attachment located on the power cable
must be fitted into the power cable holder incorporated in the battery access cover and located under
the AC (mains) power socket. Refer to section
4.2, “Connecting to External AC Power” .
•
The power supply to which the ventilator is connected (both AC and DC) must comply with all
applicable
standards and provide electrical power corresponding to the voltage characteristics
inscribed on the rear of the ventilator to ensure correct operation. Refer also to the electrical
specifications found in
Appendix A, “Specifications” .
•
Ensure that the ventilator’s internal battery is fully charged before connecting the ventilator to an
external DC power source. Powering the ventilator using an external 12– 30 VDC power source (via the
DC power cable) does not enable charging of its internal battery.
•
Due to its limited internal battery’s reserve capacity, the ventilator should only be operated
occasionally while powered by its internal battery. Ensure that the internal battery never becomes fully
discharged.
•
When using a car auxiliary adapter (cigarette lighter) ensure the car has been started prior to plugging
in the ventilator’s DC adapter.
•
Even if the “INTERNAL BAT“ indicator is off, charge of the battery may sometimes be incomplete
regardless of charge time when the ambient temperature is above 104 °F (40 °C). This is due to the
characteristics of the battery’s internal heat safety device.
•
When the “LOW BATTERY“ alarm is triggered, immediately connect the ventilator to an AC power
supply to maintain ventilation and recharge the internal battery.
•
When replacing the ventilator’s internal battery, the ventilator must be disconnected from all external
power supplies and turned off.
•
Batteries should be disposed of according to environmental legislation in your country and locality.
•
Never expose any batteries to direct flame.
•
Never touch the ventilator’s internal components, including the battery, and the patient
simultaneously.
