What Is a Demand Valve?

A demand valve is a respiratory device that delivers oxygen to a patient only when they inhale. Unlike constant flow oxygen systems, the demand valve reduces oxygen waste and allows for more efficient, on-demand delivery—making it ideal for both emergency and transport scenarios.

How Does It Work?

The oxygen demand valve connects to an oxygen source and activates when the user inhales. It remains closed between breaths, conserving oxygen and reducing unnecessary flow. These valves are commonly used with:

  • Bag valve masks (BVMs)

  • Resuscitation masks

  • Positive pressure devices

Some valves include pressure relief features or connect to flow selector valves for adjustable oxygen output.

Key Benefits of Using a Demand Valve

  • Oxygen conservation: Delivers only when needed, reducing waste

  • Improved patient comfort: No continuous flow into the mask

  • Enhanced control: Useful in both manual and automated systems

  • Portable and versatile: Compatible with most oxygen tanks and emergency kits

Who Should Use a Demand Valve?

Demand valves are commonly found in:

  • Ambulances and EMS kits

  • Emergency rooms and trauma centers

  • Dental and surgical clinics

  • First responder and public safety equipment

They are essential for any team that may need to deliver oxygen quickly and efficiently in high-stress situations.
