mask exhalation port. However, when the CPAP machine is not operating, enough fresh air will 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 suocation. This warning applies to most
models of CPAP systems.
• If oxygen is used with the device, the oxygen ow must be turned o when the device is not
operating.
Explanation of the Warning: When the device is not in operation, and the oxygen ow
is left on, oxygen delivered into the ventilator tubing may accumulate within the device enclosure.
Oxygen accumulated in the device enclosure will create a risk of re.
• At a xed ow rate of supplemental oxygen ow, 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 CPAP and bi-level machines.
• At low CPAP or EPAP pressures the ow through the exhalation port may be inadequate to clear all
exhaled gas from the tubing. Some rebreathing may occur.
• Attaching an exhalation device requires therapy pressure level adjustment to compensate for
increased leak.
