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.
VPAP machines were developed to give even a better treatment for obstructive sleep apnea syndrome than the usual CPAP therapy that supported breathing only during inhalation. Many obstructive sleep apnea patients use Bi-level machines because they need a lower pressure during exhalation.
