What should you know about volume oriented spirometer?

A volume-oriented spirometer focuses on the volume of air entering and leaving the lungs. You breathe through a mouthpiece while the device records the movement, then the clinician compares the tracing with your symptoms and examination. It can help assess airflow problems and track change over time, but the reading is only one part of a respiratory assessment.

Good technique matters. A loose seal, coughing, hesitation, or stopping too soon can alter the tracing. You may be asked to repeat the manoeuvre several times so the team can check that the recordings are consistent. Forceful breathing may cause temporary dizziness; pause and tell the tester if this happens.

Wear clothing that allows your chest and abdomen to expand. Follow the clinic's advice about meals, smoking, exercise, and inhalers before testing. Bring a medicine list and any inhalers you use. Sit upright, keep your lips sealed around the mouthpiece, and follow the tester's timing for a deep breath and a firm, sustained exhalation. Ask for a break if you feel unwell.

Arrange medical review for ongoing breathlessness, repeated wheezing, reduced exercise tolerance, or a cough that continues. Get urgent help if breathing becomes severe or sudden, you cannot speak normally because of breathlessness, your lips look blue or grey, you faint, or you develop chest pain. A spirometry appointment should not delay urgent assessment.

Ask which volumes are being measured, whether your result was technically reliable, and what the findings mean alongside your symptoms. Confirm whether medicines should be withheld and when the report will be discussed.
