PR System One Remstar Auto CPAP with A-Flex

The PR System One Remstar Auto CPAP Machine with A-Flex is an intelligent solution that knows when, why, and how changes should occur to consistently and effectively provide optimum sleep therapy. New System One technologies like Humidity Control with Dry Box and Resistance Control for use with any mask, all are helping users achieve effective therapy.

System One Humidity Control and Dry Box Technology

Many CPAP/APAP users find that the addition of heated humidity to their sleep therapy system improves comfort and helps with overall compliance. The optional System One Heated Humidifier delivers optimum humidity, drastically reduces rainout, and provides ultimate comfort throughout the night by analyzing and adjusting to ambient temperature, changing environmental conditions, relative humidity, and therapy flow. Revolutionary Dry Box technology isolates the humidfier's water source from the inner workings of the device to protect against accidental spillage and water damage.

System One Resistance Control

System One Resistance Control achieves complete system comfort by enabling the device and mask to work optimally together. Through simple settings, the System One Resistance Control instructs your APAP to compensate for variable resistance characteristics related to different masks. The result is synchronous pressure delivery and the assurance you can enjoy the full benefits of Respironics Flex comfort technologies no matter which mask is used.

Advanced Event Detection, Reporting & Response

The System One REMstar AUTO tracks, and adjusts therapy levels to respond to, many common OSA related events including Hypopneas, Flow Limitation, Respiratory Effort Related Arousal, Snores, and Leaks. In addition the REMstar AUTO can detect many symptoms beyond classic OSA -- such as clear airway apneas and periodic breathing -- that may indicate the need for specialized therapy.
