Other Airway Pressure Devices
CPAP machines have been most extensively studied and shown to be most effective with many cases of sleep apnea. However, if using the machine causes discomfort patients aren't able to alleviate, other airway pressure devices may be an option. One option is an auto-CPAP machine, which automatically adjusts air pressure as the individual sleeps when it detects their breathing is becoming obstructed. Another option is a BPAP unit, which stands for bilevel positive airway pressure. BPAP machines also use masks to deliver air but, unlike CPAP machines, they can use multiple air pressures. They increase the pressure when patients inhale and reduce it when they exhale. This helps patients who find it tiring to exhale against the high air pressure of the CPAP machine.
