What It Involves
A breathing test measuring how much air you can move in and out of your lungs and how fast, usually by blowing hard into a mouthpiece connected to a spirometer. It's used where respiratory demand or exposure risk is higher - offshore, diving and some driving medicals request it, especially if your history flags asthma, smoking or a previous chest condition.
What to Bring
Valid photo ID (passport or driving licence) (and 1 more items)
Frequently Asked Questions
Avoid smoking or vaping for at least an hour beforehand - it can temporarily affect your reading, though it won't change your underlying result.
No - it just requires blowing hard and steadily into a mouthpiece for a few seconds; some people find it tiring but it's not painful.
