Demand Valve Resuscitator with 6 ft Supply Hose & Universal Face Mask

Demand Valve Resuscitator

The O‑Two Demand Valve Resuscitator is a high‑performance, oxygen‑powered device designed to deliver rapid, controlled, and reliable ventilation in emergency situations. Engineered for EMS crews, first responders, and clinical teams, it combines manual ventilation capability with an intuitive demand‑breathing function.

This resuscitator features a front‑mounted manual ventilation button, strategically positioned so responders can maintain a secure mask seal using both hands. This eliminates the need for awkward top triggers or lever mechanisms. The fixed manual flow rate of 40 L/min adheres to current resuscitation guidelines, ensuring consistent oxygen delivery every time it’s activated.

During spontaneous breathing, the device provides 100% oxygen on demand, requiring only minimal inspiratory effort from the patient. Its advanced demand‑flow system supports a peak flow rate of up to 140 L/min, making it suitable for patients experiencing significant respiratory distress.

Built for durability and field performance, the O‑Two Demand Valve Resuscitator offers a fast, simple, and effective solution for ventilating non‑breathing patients while also supporting those who can still breathe but require enriched oxygen concentrations. Its integrated pressure relief system and audible over‑pressure alarm add essential layers of safety during operation.
