Auto CPAP is a newer variant that continuously monitors the patient and sets the air pressure to the lowest value that prevents obstruction. This value may change during the night, and may change over weeks and years. Patients report increased comfort with Auto CPAP, since they are generally exposed to lower pressures throughout the night.
Auto CPAP can be used in lieu of traditional titration when the patient uses auto titration for one or more nights. The clinician reads the profile of the pressure that was used during the trial, to determine the pressure the fixed CPAP unit will have. Alternatively, Auto CPAP can be used on a permanent basis. In this scenario, no titration is necessary, because the device is self Titrating. This model of therapy, is gaining popularity because of its simplicity and increased patient comfort. However, there are not enough outcome studies to show it is more cost effective than fixed CPAP.
