What should you know about wireless spirometer?

It may be used at home or during an appointment, depending on the equipment and your clinician's plan. The connection makes it easier to record, review, and share readings, but it does not replace a clinical assessment when symptoms need attention.

Spirometry looks at the amount of air you can move and how quickly you can push air out after a full breath in. A clinician considers the tracing, the quality of your effort, your symptoms, examination findings, and relevant health history together.

A reading can be affected by a loose mouth seal, coughing, stopping early, or not taking a full breath before blowing. For that reason, you may be asked to repeat the manoeuvre several times. A change in a number on its own is not a diagnosis.

Follow the instructions provided for your specific device and app. Sit upright if advised, fit the mouthpiece securely, and give the strongest sustained blow you can after breathing in fully. Keep the device clean and dry, and use a new or cleaned mouthpiece as instructed.

Record readings at the times agreed with your clinician rather than repeatedly checking because of worry. Bring the device or its results to your appointment if requested. If a result seems unusual, note any breathlessness, cough, wheeze, chest tightness, recent illness, or inhaler use alongside it.

Seek urgent medical help for severe or rapidly worsening breathlessness, trouble speaking because of breathlessness, blue or grey lips, fainting, confusion, or chest pain. Do not delay care while trying to obtain a spirometer reading.

Arrange a clinical review for a new persistent cough, recurring wheeze, reduced exercise tolerance, or breathing symptoms that are interfering with sleep or daily activities. Contact the clinician managing your care if your agreed action plan tells you to act on a particular pattern of symptoms or readings.

Ask which readings matter for your situation, how often you should test, and whether medicines should be used before a scheduled measurement. Clarify who will receive the data, what to do if the connection fails, and which symptoms require you to seek help regardless of the displayed result.
