The Oxylator EMX is a “positive pressure” resuscitation and inhalation system that uses a patented, patient responsive technology. It requires no power source other than a 50 PSI supply of compressed oxygen or air. It operate with either the mask or ET-tubes. The Oxylator EMX is not a “demand valve” or “vent”, but it is a new technology pressure limited / flow triggered ventilation device, designed to replace the BVM during CPR/resuscitation and transport. Small, light weight, rugged, easy to use, and easy to “decon”.
