HFGP Consent Form for Spirometry

Patient Details


Spirometry is a breathing test used to assess how well your lungs are functioning. It measures the amount of air you can breathe in and out and how quickly you can exhale.

The test requires you to take a deep breath in and then blow out as hard and as fast as possible into a mouthpiece several times.

Bronchodilator Testing

Your doctor may request pre- and post-bronchodilator spirometry.

This involves:

  1. Initial spirometry testing.

  2. Administration of a bronchodilator inhaler (usually salbutamol/Ventolin®).

  3. Waiting approximately 10 to 15 minutes.

  4. Repeating the spirometry test.

This helps assess whether your airways respond to bronchodilator medication.

All procedures have risks and side effects. It is important that you understand the specific side effects of any treatment/procedure/test

Please read and cross the below statements to indicate that you have been told of these side effects and understand their implications.

Serious reactions are extremely uncommon. Emergency equipment and trained staff are available should an unexpected reaction occur.

Possible Risks and Side Effects

Spirometry is generally very safe; however, it may occasionally cause:

  • Temporary dizziness or light-headedness

  • Shortness of breath or coughing

  • Chest discomfort

  • Fatigue from repeated breathing manoeuvres

Possible side effects from bronchodilator medication:

  • Tremor or shakiness

  • Palpitations or awareness of heartbeat

  • Mild headache

  • Nervousness or feeling jittery

  • Temporary increase in heart rate

Contraindications and Safety Screening

Spirometry may not be suitable in certain situations because forceful breathing can place strain on the chest, eyes, abdomen, blood vessels, and recent surgical sites.
