You may have already been given an inhaler. We would ask you to try and NOT use your blue inhaler 4 hours before the test, if possible. If you are having difficulty breathing and need to use it then it is important to tell the nurse that you have done. Please can you bring all your Inhalers with you

The test is quite hard work and we suggest that you do not eat a big meal before the test. Please do not wear tight clothing. It is also a good idea to empty your bladder.




The nurse will make sure that the it is safe for you to do the test and will ask you several questions beforehand.


You may not be able to do the test if you have recently had an operation, an ear infection, treatment for your eyes, a heart attack, a stroke, a hernia or chest pain. The nurse will discuss all this with you when you come for your appointment but you may like to telephone ahead of your appointment if you are concerned.


The nurse will also take your blood pressure, measure your height and weight to prepare you for the breathing test. She will also ask you some questions, if you have ever smoked, this will include details about the number of years and how many cigarettes you smoked per day. This helps to consider whether smoking might have contributed to your present breathing problems.

Make sure you are sitting comfortably

Show and explain the Spiro meter to you

Following this you will be giving the opportunity to practice using the Spiro meter. You will then be asked to blow slowly and steadily, and then very fast into the mouth piece attached to the Spiro meter. It is important to do this to the best of your ability to achieve accurate results. This can be tiring and cause slight dizziness, this will pass quickly.


You will not be asked to continue if the test makes you feel unwell. The nurse will print out the results and explain these to you. It might be necessary for you to have another consultation with person that referred you for the test.
