What should you know about a Polymed spirometer?

You breathe into a mouthpiece while the device records the force and speed of exhalation. The results can help a clinician assess airflow limitation, compare breathing before and after an inhaled medicine, and follow a known lung condition. The device does not diagnose a condition by itself; the pattern is interpreted alongside symptoms, examination findings, and your medical history.

Wear comfortable clothing and follow the clinic's instructions about meals, smoking, and inhalers. Sit upright, seal your lips around the mouthpiece, and follow the technician's prompts. You may be asked to inhale fully and then blow out as hard and as long as you can. Several attempts are common because consistent technique makes the reading more useful. Tell the technician if coughing, chest pain, dizziness, or breathlessness stops you.

Seek urgent care for severe or rapidly worsening breathlessness, blue or grey lips, fainting, confusion, or chest pressure. After testing, contact the clinic if breathing remains unusually difficult or you feel unwell. A routine appointment is appropriate when cough, wheeze, or reduced exercise tolerance persists, even if a home reading seems reassuring.

Ask which part of the result was outside the expected range, whether your inhalers should be changed before repeat testing, and when your breathing should be checked again.
