Can You Use a CPAP Oxygen Machine While Fasting?

Answered by: Alimah Safiyya-Maryam Ahmed


Can you use a CPAP oxygen machine while fasting?

In the name of Allah, the Most Gracious, the Most Merciful


CPAP machines use a continual stream of air – the same mixture of oxygen, nitrogen and other elements in the air we normally breathe – to keep your airways open while you sleep. During CPAP therapy, a special mask delivers the stream of air directly to your airway to help prevent the soft tissues at the back of your throat from collapsing. It’s these intermittent periods of collapse that interfere with normal breathing, producing the interruptions in breathing that are the hallmark of Sleep Apnea. [1]

Therefore, using a CPAP oxygen machine will not nullify the fast as there is nothing entering the body apart from the normal air we breathe. However, if a person used a humidifier with their machine this would break the fast due to water vapour entering the body. [2]

Only Allah knows best
