Using DC Power to Run the VPAP Adapt SV
The VPAP Adapt SV can be run on DC in case of power failure. ResMed supplies
separately a converter that allows a 12V or 24V battery to be connected to the
DC input of the VPAP Adapt SV. When using a DC power supply, the power is
turned on and off via the switch on the converter, and not the power switch at
the back of the VPAP Adapt SV. The DC converter is a separate accessory that
can be purchased through your ResMed distributor.
The humidifier heater will be automatically disabled when the VPAP Adapt SV is
operating from the DC supply.
Power consumption of the VPAP Adapt SV varies with treatment settings.
Adequate battery type and sizing is required before operation on DC, and it is
recommended that you contact ResMed’s Technical Services division or see
ResMed's website for information on your specific application.
!
CAUTION
The VPAP Adapt SV uses 30V DC power. Only connect the VPAP Adapt SV
to DC power using the VPAP Adapt SV DC Converter (P/N 26928) specified
for this application.
Supplemental Oxygen
The VPAP Adapt SV is designed to be compatible with the use of low flow
oxygen therapy provided from an external source and supplied at a fixed rate of
up to 15 L/min. At a fixed flow rate of supplemental oxygen flow, the inhaled
oxygen concentration will vary, depending on the pressure settings, patient
breathing pattern, mask selection, and the leak rate. This warning applies to most
types of bilevel machines.
!
WARNING
• If oxygen is used with this device, the oxygen flow must be turned off
when the device is not operating.
Explanation: When the device is not in operation, and the oxygen flow is
left on, oxygen delivered into the ventilator tubing may accumulate
within the device enclosure and create a risk of fire.
• Always begin VPAP Adapt SV therapy before the oxygen supply is
turned on.
• Always turn the oxygen supply off before stopping VPAP Adapt SV
therapy.
• Oxygen supports combustion. Oxygen should not be used while
smoking or in the presence of an open flame.
