ResMed VPAP Auto Guia Del Usuario página 11

When the device is turned on and functioning properly, new air from the
device flushes the exhaled air out through the mask vent holes. However,
when the device is not operating, insufficient fresh air will be provided
through the mask, and the exhaled air may be rebreathed. Rebreathing of
exhaled air for longer than several minutes can, in some circumstances, lead
to suffocation. This applies to most models of PAP devices.
In the event of power failure or machine malfunction, remove the mask.
•
The VPAP Auto can be set to deliver pressures up to 20 cm H
•
unlikely event of certain fault conditions, pressures up to 30 cm H
possible.
If oxygen is used with this device, the oxygen flow must be turned off when
•
the device is not operating. If oxygen has been left on while the device is not
operating, disconnect the oxygen and wait 60 minutes before turning on the
device again.
Explanation: When the PAP device is not in operation and the oxygen flow is
left on, oxygen delivered into the ventilator tubing may accumulate within the
PAP machine enclosure and create a risk of fire. This applies to most types of
PAP machines.
Oxygen supports combustion. Oxygen should not be used while you are
•
smoking or in the presence of an open flame.
Always ensure airflow is being generated by the device before the oxygen •
supply is turned on.
Always turn the oxygen supply off before stopping the airflow from the
•
device.
Note: At a fixed rate of supplemental oxygen flow, the inhaled oxygen
concentration will vary, depending on where the oxygen is introduced, the
pressure settings, patient breathing pattern, mask selection and leak rate.
Do not use the VPAP Auto if there are obvious external defects or
•
unexplained changes in performance.
Do not open the VPAP Auto case. There are no user serviceable parts inside.
•
Repairs and internal servicing should only be performed by an authorized
service agent.
Explosion hazard—do not use in the vicinity of flammable anesthetics.
