Auto CPAP or APAP Machines. Similar to the CPAP machine, auto adjusting or APAP machines automatically calculate a patientâs required pressure and adjust to a comfortable level without any pre-set programming. These machines are ideal for patients who have various pressures during the night.
An example of a fixed pressure CPAP machine would be 12cm/H2O, and that means once the machine has ramped up it will continue to blow out 12cm/H2O the entire course of the night. People sometimes confuse standard or fixed pressure CPAP with Auto CPAP because their machine comes with a ramp mode feature.
