The VPAP Adapt SV is NOT a life support ventilator. The entire manual should be read before using the VPAP Adapt SV. Advice contained in this manual should not supersede instructions given by the prescribing physician. The VPAP Adapt SV should be used with masks and accessories recommended by ResMed or the prescribing physician. Use of incorrect masks and accessories may adversely affect the function of the VPAP Adapt SV. The VPAP Adapt SV is designed for use with masks that allow exhaled gases to be flushed out through vent holes. Exhaled gases will be rebreathed if the mask is worn with the machine turned off, or the vent holes are occluded. If this occurs over prolonged periods, suffocation may occur. In the event of power failure or machine malfunction, remove the mask. The air flow for breathing produced by this device can be as much as 11ºF (6ºC ) higher than the temperature of the room. Caution should be exercised if the room temperature is warmer than 90ºF (32ºC). The VPAP Adapt SV can be set to deliver pressures up to 25 cm H2O. In the unlikely event of certain fault conditions, pressures of up to 40 cm H2O for less than one second are possible. The VPAP Adapt SV is not suitable for use in the vicinity of flammable anesthetics. If oxygen is used with the VPAP Adapt SV, the oxygen flow should be stopped when the device is not operating. If oxygen flow continues when the device is not operating, oxygen may accumulate within the device and create a risk of fire. Do not use the VPAP Adapt SV if there are obvious external defects or unexplained changes in performance. Do not open the VPAP Adapt SV case. There are no user serviceable parts inside. Repairs and internal servicing should only be performed by an authorized service agent.
CAUTIONS You should report unusual chest pain, severe headache or increased breathlessness to your physician. An acute upper respiratory tract infection may require temporary discontinuation of treatment.
The following side effects may arise during a course of therapy with the VPAP Adapt SV: • drying of the nose, mouth, or throat • bloating • ear or sinus discomfort • eye irritation • skin rashes • chest discomfort.

Using DC Power to Run the VPAP Adapt SV
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. •
