What should you know about Geeky Medics spirometry?

Spirometry uses a mouthpiece connected to a spirometer. You breathe in fully, seal your lips around the mouthpiece, and blow out as hard and long as instructed. The recording can help clinicians assess airflow and compare results with expected values for your age, height and sex. A reduced flow may occur with conditions such as asthma, COPD or bronchiectasis, but a result needs clinical context and good technique. A cough, a leak around the mouthpiece or stopping early can affect the reading.

Follow the clinic's instructions about inhalers, meals, smoking and exercise before testing. Wear comfortable clothing and tell the clinician about chest pain, recent surgery, a current infection or medicines. During the test, sit upright, follow each command, and take a short rest between attempts if you feel light-headed. You may be asked to repeat the manoeuvre or use a reliever inhaler before another set of readings. The related Spirometer page explains the device, while the Spirometry page describes the clinical test.

Seek urgent help for severe breathlessness, blue or grey lips, fainting, confusion, or chest pain that does not settle. Contact a clinician promptly if breathing becomes worse after testing, you cough blood, or your usual inhaler is not helping. A spirometry result alone does not diagnose a condition; arrange follow-up if the report is abnormal or symptoms persist.

Ask what each measured value means, whether the effort was technically adequate, and whether repeat testing or an inhaler response test is needed. Ask how your symptoms fit with asthma, COPD, chronic cough or bronchiectasis, and when you should review treatment. If smoking is relevant, discuss a Smoking Cessation Programme; if inhalers are prescribed, ask for an Inhaler Therapy technique check.
