Cardiovascular effects of CPAP and auto-CPAP during sleep in patients with OSA

Treatment with auto-CPAP therapy With the ongoing advancements in technology through the past decade, auto-CPAP has displayed an advantage over fixed pressure CPAP in its ability to treat the patient’s changes in sleep state, sleep position, or longterm changes in the patient’s condition. Several brands of auto-CPAP devices are commercially available, with the common objective of maintaining airway patency by adapting the delivered pressure in response to partial and total closure of the upper airway. The operational algorithm of each manufacturer’s device differs considerably, and these differences can affect the ability of the devices to detect and treat respiratory events during sleep. The following two studies demonstrate these differing patient outcomes based on the auto-CPAP device used. 0 36 72 108 144 0 5 10 15 20 25 30 35 Controls Snorers
