Auto CPAP Machines (APAP)
Auto CPAP machine (APAP) can adjust the CPAP pressures automatically. These CPAP machines have sensors embedded and keep monitoring your breathing events. If they find you do not snore or you do not stop breathing, your CPAP machine will use a lower pressure (still higher than the minimum pressure). If it detects you start sleep apnea, it will automatically increase the pressure (it won't exceed your CPAP settings' up limit) until you are back to normal breathing.
It is much more comfortable to use an auto CPAP machine than regular manual CPAP machine. Usually the better the machine is, the more sensors it has, and the more events it monitors. We highly recommend ResMed S9 AutoSet with H5i and ClimateLine. It is the most sophisticated machine at auto CPAP level.
