The S9 VPAP Auto, the next generation VPAP from ResMed, is an auto-adjusting bilevel machine designed specifically to meet the needs of patients with non-compliant OSA (obstructive sleep apnea). The S9 VPAP Auto series employs a special AutoSet algorithm to continuously monitor breathing. This device also features optional wireless monitoring, central sleep apnea (CSA) detection and optional integrated oximetry. It is available with the H5i heated humidifier and the ClimateLine tubing to help regulate temperature and humidity levels. Plus, the S9 VPAP Auto operates quietly, using the Easy-Breathe motor, to ensure sleep isn't disrupted by noise.
