Cardiopulmonary exercise test: CPET
Aims: to accurately measure exercise capacity for clinical use and research
|What is CPET ?||Cardiopulmonary Exercise Testing (CPET) is non-invasive simultaneous measurement of the cardiovascular and respiratory system during exercise to assess a patient’s exercise capacity.|

|Why do a CPET ?||
CPET is used for many specific reasons, but in general it can
|What does it involve ?||
During the CPET test, once consent has been taken and the preliminary tests (Hb, spirometry) are complete, the patient undertakes a 'ramped protocol test' on a cycle ergometer.
We attach a 12 lead ECG, blood pressure cuff, saturation probe and a soft rubber face mask with a turbine to measure the expired gases before the test starts. The patient then rests for 3 minutes then begins to cycle. After 3 minutes of unloaded cycling the resistance begins to increase. The patient continues pedalling at 60rpm until they can no longer cycle, unless they have chest pains, feel discomfort or if complications occur.
During every test exercise physiologists trained to carry out the CPET are present, in conjunction with a doctor.
Reports from the test are written up and sent back to the medical team.
