DHD Healthcare spirometer: what to know

A Spirometer records airflow and lung volumes during forceful breathing. During Spirometry, you usually sit upright, breathe in fully, seal your lips around a mouthpiece, and blow out as hard and long as instructed. The test may be repeated to check consistency or after an inhaled medicine, depending on the clinical question.

The device produces measurements that help a trained professional assess breathing symptoms such as wheeze, cough, or breathlessness. Results need to be interpreted with your symptoms, examination, age, height, medical history, and test technique. A device reading alone does not identify every lung condition.

Follow the clinic’s instructions about inhalers, smoking, meals, and strenuous activity before the appointment. Wear comfortable clothing and tell the tester if you feel unwell, have chest pain, have recently had surgery, or become dizzy during forced breathing. Give a strong, sustained effort while keeping a tight seal around the mouthpiece; ask for a pause if you feel unable to continue.

The mouthpiece and equipment should be handled according to the service’s infection-control process. Ask when your report will be reviewed and whether you need repeat testing or further assessment.

Stop the test and tell the clinician immediately if you develop chest pain, severe breathlessness, faintness, bluish lips, or intense wheezing. Seek urgent help for sudden severe breathing difficulty, confusion, or inability to speak in full sentences. Arrange medical review for breathlessness that is new, worsening, or limiting ordinary activity.

Ask: What question is the test designed to answer? Should I pause any inhaler beforehand? Were the results reliable? What do the measurements mean alongside my symptoms? Do I need bronchodilator testing, imaging, or another review?
