Cardio pulmonary exercise test: CPET
Aims: to accurately measure exercise capacity for clinical use and research
|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.|

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 rarely if the physiologist stops the test.
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.

The CPET tests are carried out at 3 sites;
University College London Hospital, 1st floor podium in Clinic A-
Alternate Mondays, every Thursday and Friday
UCLH at Westmorland Street - alternate Mondays in the 'Cystectomy Clinic'
Patients having surgery at The Whittington Hospital, Archway are tested at the UCL Hospitals or the Royal Free.
Gurinder Rayat was our student 2015-16, and Tapi Mafuva will be joining us in August 2016.
