Benefits of the ResMed SULLIVAN VPAP II ST-A

• VPAP provides optimal patient/ventilator synchronization with automatic leak compensation (Vsync) and the ability to control inspiratory time (TiCONTROL). 
• VPAP gives clinicians ability to assess for mask fit and evaluate the effects of changing pressures via real time LCD monitoring of tidal volume and leak.
• Extremely quiet operation doesn't disturb users or their bed partners.
• Very comfortable air delivery and pressure transitions minimize sleep disturbances caused by many devices.
• VPAP's light weight and its convenient handle makes the device great for travel.

ResMed VPAP II Systems: Designed for Optimal Synchronization

Recent studies show that all bilevel therapy patients using nasal masks experience mouth leaks, which interfere with a bilevel device's cycling sensitivity and cause poor synchronization between the bilevel device and user. Poor synchronization forces patients to exhale against a higher pressure, which increases the work of breathing and causes fragmented sleep, muscle fatigue, and reduced usage.

ResMed VPAP II systems provide three levels of defense to counteract the effects of mouth and mask leaks: ResMed's world leading mask designs, including the Mirage® Full Face Mask Series 2, Vsync technology to manage mouth and mask leaks, and patented TiCONTROL features to optimize therapy comfort and effectiveness.
