The Automatic Positive Airway Pressure (APAP) machine works in a similar way a CPAP machine works. To keep your airways free from breathing difficulties, the APAP machine carries the pressurized air via a mask. It is a non-invasive treatment for sleep disorders. The APAP machine delivers the air pressure that helps in keeping your throat from collapsing that eventually enables you to sleep in the night without any sleep disorder.
APAP machine has two settings, a low range setting, and a high range setting. The machine will keep on fluctuating during the night as it automatically modifies itself to suit your relevant requirements at any given moment throughout your sleep.
