Usage Note

Respiratory is almost always used attributively (before a noun). Unlike the everyday word breathing, it belongs to formal and medical English. You cannot say ✗ 'His condition is respiratory' — instead say 'He has a respiratory condition.'

He was taken to the hospital with a respiratory infection.
respiratory is an adjective; it must modify a noun.

Synonym discussion

Sense: adjective/1

Respiratory is the standard medical term for anything involving the process of breathing. Breathing is the everyday, non-technical word — you would say 'breathing exercises' in a yoga class, but 'respiratory therapy' in a hospital. Pulmonary is narrower and refers specifically to the lungs themselves: a pulmonary embolism is a blood clot in the lung, whereas a respiratory infection can affect the nose, throat, airways, or lungs. Use respiratory when you want a formal, clinical tone that covers the entire breathing system; use breathing for casual conversation; and use pulmonary only when the lungs alone are the focus.

Etymology

LatinEnglish

From Latin respirare, made up of re- ('again') and spirare ('to breathe, blow'). The literal sense is 'to breathe again,' which evolved into the modern medical meaning of anything connected with the action of breathing.
