Pre-Test Instructions

Prior to performing the Lung Function Tests, the Respiratory Physiologist will fully explain the nature of your tests. Please feel free to ask any questions.

The Physiologist will measure your height and weight as your lung function varies with these factors.

It is often helpful if you take a list of any medication you are currently using. You will be sent a letter informing you that you may need to discontinue taking some respiratory medication prior to attending for your test appointment.  This will include inhalers and sometimes antihistamines and other tablets.  Please make sure you read all the information you receive with your appointment as failure to stop some medication may mean your test will have to be cancelled.

You may also be advised:

  • Not to wear tight clothing for your appointment as this constricts your lungs.
  • Not to smoke for at least 1 hour before your appointment
  • Not to take vigorous exercise, 30 minutes before your appointment
  • Not to have a heavy meal upto 2 hours prior to your appointment
  • Not to consume alcohol for a minimum of 4 hours

There are some reasons when lung function tests cannot/may not be performed. These include:

  • Heart attack within the last month
  • Any recent surgery to the stomach, chest or eye
  • Pneumothorax (collapsed lung)
  • Current or recent chest infection (within the last 2 weeks) 
  • Chest pain on the day of your test
  • If you have attended Accident and Emergency in the last 2 to 3 days

If you have experienced any of the above then it is advisable to contact the department before your appointment date.
