What should you know about Buhl spirometer?

A spirometer records the volume of air you can breathe out and the speed of that breath. During Spirometry, you usually breathe through a mouthpiece while wearing a nose clip, take a full breath, and blow out hard for as long as instructed. The clinician may repeat the manoeuvre to check consistency or compare readings before and after an inhaled medicine. The device does not diagnose a condition by itself; results are interpreted alongside symptoms, examination findings, and medical history.

Wear comfortable clothing and follow the clinic's instructions about meals, smoking, exercise, and whether to pause particular inhalers. Tell the clinician if you feel unwell, have chest pain, recently had surgery, or find forceful blowing difficult. Sit upright, seal your lips around the mouthpiece, and follow the coaching closely. Feeling briefly light-headed can happen after repeated forceful breaths; tell the clinician and rest if it occurs.

A spirometer is a testing device, not emergency treatment. Seek urgent help for severe breathlessness, blue lips, fainting, chest pain, or rapidly worsening wheeze. Contact the testing centre before attending if you have a significant respiratory infection or cannot safely perform forceful blows; they may reschedule or give tailored advice.

Ask what the test is checking, whether any inhaler should be withheld, and when you will discuss the result. You can also ask whether repeat testing, bronchodilator testing, or another breathing assessment is appropriate for your symptoms.
