MEDICAL INFORMATION
Note: The mask system does not contain latex materials. If the patient has ANY reaction to any part of the mask system, discontinue use.
WARNINGS
•This mask should be used only with CPAP or bilevel systems recommended by a physician or respiratory therapist. A mask should not be used unless the CPAP or bilevel system is turned on and operating properly.
Explanation of the Warning: CPAP or bilevel systems are intended to be used with special masks with connectors which have vent holes or separate exhalation devices to allow continuous flow of air out of the mask. When the CPAP or bilevel device is turned on and functioning properly, new air from the flow generator flushes the exhaled air out through the mask exhalation port. However, when the CPAP or bilevel device is not operating, enough fresh air may not be provided through the mask, and exhaled air may be rebreathed. Rebreathing of exhaled air for longer than several minutes can in some circumstances lead to suffocation. This warning applies to most models of CPAP or bilevel systems.
•The exhaust vent flow is lower at lower mask pressures (see Pressure/Flow curve). If the mask pressure during expiration is too low, there may not be enough exhaust vent flow to completely flush the air delivery hose of exhaled air before the start of the next inspiration.
•If oxygen is used with the CPAP or bilevel device, the oxygen flow must be turned off when the flow generator is not operating.
Explanation of the Warning: When the CPAP or bilevel device is not in operation, and
