Treatment of cluster headaches is one of the most common uses for the oxygen demand valve which synchronises oxygen delivery with the patient’s breathing.
Oxygen demand valves only deliver oxygen when the patient breathes in and shut off the flow when they breathe out. Demand valve oxygen therapy (DVOT) allows 100% oxygen to be inhaled, and are therefore more effective, providing better pain relief compared to conventional non-rebreathe masks and other delivery systems.

• Patients are able to self-administer very high volumes of oxygen quickly and effortlessly
• Minimises discomfort and maximises the speed of therapy
• Can be used with face mask or mouth
