The Dreamstation Auto CPAP machine makes the breathing support more comfortable. It adjusts the pressure on the patient's airway, and the pressure can be adjusted in many stages. The advanced features include SmartRamp and Opti-Start, which helps address enduring apnea events that may occur early in therapy. The A-Flex pressure relief option can also lighten the transition between breathing and reduce overall exhalation pressure to make breathing feel more natural. The Dreamstation Auto CPAP machine also supports Bluetooth connectivity.
