Ultraflow™ Oxygen Demand Valve

The oxygen demand valve is intended for patient self-administration of oxygen to adult and paediatric patients for the symptomatic relief of pain due to cluster headache. The demand valve synchronises oxygen delivery with the patient’s breathing.

Demand valve oxygen therapy (DVOT) allows 100% oxygen to be inhaled, which can provide effective relief of pain from cluster headache, and has been shown to be a preferred delivery method by patients⁽¹⁾.

• 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 mouthpiece

Intended life: 10 years
