What should you know about geratherm spirometer?

A spirometer records airflow as you breathe through a mouthpiece. The clinician may ask you to breathe normally, take a full breath and then blow out hard for as long as instructed. Results can help identify airflow obstruction or restriction, but they are interpreted alongside symptoms, examination findings, age, height and technique. A single reading is not a diagnosis. Cough, chest tightness and wheezing can have different causes, so the result needs clinical context.

Follow the testing centre's instructions about inhalers, smoking, meals and strenuous activity; do not stop prescribed medicine unless the clinician tells you to. Wear comfortable clothing and explain if you feel unwell or have recently had chest pain or an infection. During the test, seal your lips around the mouthpiece and follow each instruction closely. Several attempts may be needed because effort and technique influence the result. Mild light-headedness can occur briefly after forceful blowing, so tell the staff immediately if you need a pause.

A spirometer is not a substitute for urgent help. Seek emergency care for severe breathlessness, blue or grey lips, inability to speak in full sentences, fainting or rapidly worsening wheezing. Stop the test and alert the clinician if you develop significant chest pain, severe dizziness or distress. Arrange medical review for persistent cough or reduced exercise tolerance rather than relying on home readings alone.

Ask what each reported measurement represents, whether your technique produced a reliable result, and whether the test should be repeated after treatment or with a bronchodilator. Ask how the findings fit your symptoms and whether further assessment is needed.
