•hypotension or significant intravascular volume depletion
•pneumothorax or pneumomediastinum
•recent cranial trauma or surgery.
Warnings
•The entire manual should be read before using the VPAP III ST-A.
•Advice contained in this manual should not supersede instructions given by the prescribing physician.
•The VPAP III ST-A 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 III ST-A.
•The VPAP III ST-A 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 VPAP III ST-A can be set to deliver pressures up to 30 cm H2O. In the unlikely event of certain fault conditions, pressures up to 40 cm H2O are possible.
•The VPAP III ST-A is not suitable for use in the vicinity of flammable anesthetics.
•The VPAP III ST-A should not be used with anesthetized patients, whose breathing depends entirely on mechanical ventilation.
•If oxygen is used with the VPAP III ST-A, 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 III ST-A if there are obvious external defects, unexplained changes in performance or unusual noises.
•Do not open the VPAP III ST-A case. There are no user serviceable parts inside. Repairs and internal servicing should only be performed by an authorized service agent.
Cautions
•At low EPAP pressures, the flow through the mask vent holes may be inadequate to clear all exhaled gases, and some rebreathing may occur.
•The air flow for breathing produced by this device can be as much as 6oC
higher than the temperature of the room. Caution should be exercised if the room temperature is warmer than 32oC.
Note: The above are general warnings and cautions. Further specific warnings, cautions and notes appear next to the relevant instructions in the manual.
