Auto CPAP is a relatively new treatment for obstructive sleep apnea based on technological advancements in standard CPAP therapy. Standard CPAP therapy delivers one set CPAP pressure whereas auto CPAP modulates pressure within a designated range of settings. Based on this inherent difference, auto CPAP carries many benefits, which includes less pressure, having two machines in one, needing fewer pressure adjustments, and less aerophagia.
Reduced Pressure
Auto CPAP machines determine how much pressure holds the airway open breath by breath. The pressure output then varies depending on individual needs. According to Andrew Senske, President of CPAP-Supply.com, "Automatic CPAP machines deliver approximately 40% less pressure throughout the course of a night compared with a CPAP machine which delivers a constant pressure." Less pressure translates into patient comfort and better adherence to CPAP use.
Two Machines in One
All auto CPAP machines have two modes. By changing the mode, auto CPAP machines have the ability to operate as either an auto CPAP machine or a standard CPAP machine. According to Pulmonaryreviews.com, "auto-CPAP machines can be used in a limited fashion to determine the pressure to be programmed into a long-term-use fixed-pressure machine." Hence, an auto CPAP machine can be used in the auto mode to determine the long term settings, after which the mode can be changed to standard CPAP to treat at the prescribed pressure. Therefore, another potential benefit of auto CPAP results from its utility in determining a patient's standard CPAP setting.
Less Pressure Adjustments
Most patients require adjustments to their standard CPAP settings over time. This may be due to changes in weight, overall health status, level of sleepiness, sleep position, or other factors. Since auto CPAP operates with a range of settings rather than one constant setting, patients are less likely to need pressure adjustments. Using a wide range of settings allows the machine to cover many treatment settings all at once.
Less Aerophagia
Delivery of pressurized air to the throat in obstructive sleep apnea sometimes results in aerophagia. \\Patients describe aerophagia as swallowing of air resulting in bloating, belching, and flatus. \According to CPAP.com, "an Auto Adjusting CPAP can sometimes help to eliminate or reduce aerophagia." Less aerophagia translates into better comfort and ability to comply with treatment.
