What is Home Oxygen Therapy?
Home oxygen therapy provides supplemental oxygen for people with certain lung or heart conditions who have low blood oxygen levels, helping ease breathlessness and reduce strain on the heart. It's typically delivered through a nasal cannula or mask, connected to an oxygen concentrator or cylinder at home.
Home oxygen is prescribed based on specific blood oxygen level measurements, not just how breathless someone feels, and using it exactly as prescribed — including the specific flow rate and hours of use — is important for getting the intended benefit.
02 · Understand
Clinical context
Using oxygen more than prescribed isn't necessarily better
Home oxygen needs to be used at the specific flow rate and duration prescribed by your doctor — using more than prescribed doesn't provide additional benefit and can occasionally cause harm for certain conditions.
