CARDIO PULMONARY EXERCISE TEST: CPET

WHAT IS CPET?

Cardio pulmonary Exercise Testing (CPET) is a non-invasive simultaneous measurement of the cardiovascular 

and respiratory system during exercise to assess a patient’s exercise capacity.  

WHAT IS DONE DURING THE CPET?

Before the test- please don't eat for 2 hours and drink no coffee or tea for 4 hours. Take all your normal medicines as usual.  

We take baseline observations and a blood test. You wear a mask to allow us to measure the gas you breathe in and out. 

Once seated on the bike, we ask you to start cycling. The bike then gets harder to cycle- and we ask you to carry on until you can't exercise any more. We record readings (such as heart rate) as you exercise.
