Extra intelligence—managing your therapy
VPAP III offers comprehensive data management features, allowing your clinician to monitor and manage your therapy.
SmartStart™ feature automatically starts and stops your device.
Smart Data™ provides you with usage and mask fit information.
Mask-fitting feature allows you to adjust your mask fit to ensure an optimal seal.
Its not Resmed's latest and greatest but it sounds like it "might" provide the data you need. Just make sure they turn the Smart Data on. I'm a bit leery since it says "Smart Data™ provides you with usage and mask fit information." What about AHI, AI, HI, Leak??
