Profile: Viasys Healthcare manufactures and distributes medical instrumentation systems for neurophysiological diagnosis & monitoring. We offer a wide range of sleep diagnostic instruments, from Apnea screener to full, multiple bed polysomnography systems with video monitoring capabilities. Our labmanager is a fully integrated sleep/wake database designed specifically to instill value in the procedures performed by the sleep lab. Our 3800 MicroBlender features delivery of accurate FlO2 mixtures from two outlet ports and has an overall flow range of 2-120 L/min, making it ideal for use with ventilators while providing flows to a flowmeter. It can also be used as a stand-alone device for mask CPAP, nasal cannulas and resuscitation bags. Our Headgear is a generic term used to reference the straps that secure CPAP mask to the patients head. Typically these devices fit over or around the head with straps, tabs and attachment points placed in easy to access positions.
