CPAP machines used for treating sleep apnea. CPAP uses an air conditioner and masks to supply moderate air pressure into the upper airway of someone while they sleep. AutoCPAP machines change slightly because they could discover a collapse of the airway by measuring immunity and respond by raising the pressure as required during the nighttime to further solve the sleep apnea. If at all possible, these devices will even examine pressures and adjust. CPAP machines portable is smaller, more comfortable masks. Benefits of CPAP therapy include better heart health, lower stroke risk, and improved alertness during the day.
