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 12 V or 24 V battery to be connected to the DC input of the VPAP Adapt SV. When using DC, power is turned on and off via the switch on the connector that connects the
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 ResMed's website for information on your specific application.
CAUTION
! The VPAP Adapt SV uses 30 V 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.
WARNINGS
! • 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.
