Pre-test assessment describes the next step after deciding to do a cardiopulmonary exercise test (CPET). The indication for the test must be defined, with clear end points. A CPET is a very safe test. There are well-defined conditions which increase the risk. The most serious side effects are related to heart problems, most commonly seen in subjects with unstable heart disease. Careful scrutiny of the resting electrocardiogram (ECG) is imperative prior to the test. If the subject is unwell, e.g. with a viral illness or an exacerbation of asthma, the test should be postponed. On the day of the test, the subject should take their usual medication. Caffeine and alcohol should be avoided on the day of a CPET. A light meal should be taken at least 30 minutes beforehand.

Cardiopulmonary Exercise

This chapter describes the changes that occur when anaerobic processes start to supplement aerobic metabolism during a cardiopulmonary exercise test (CPET). Lactic acid is produced, which is buffered by bicarbonate to produce carbon dioxide and water. The anaerobic threshold (AT) should be seen when VO2 is at least 40% of predicted maximum oxygen uptake (VO2max). A low AT indicates poor oxygen delivery to muscles. This can be seen in heart disease, peripheral vascular disease or anaemia. AT is useful for predicting operative risk.

Predicted Values

This chapter describes how cycle ergometer and treadmill tests suit different subjects. A standard cardiopulmonary exercise test (CPET) involves a ramp increase in workload, until the subject’s symptoms prevent them from exercising any further. The exercise phase of the test is preceded by resting and then unloaded cycling, and followed by the recovery phase. Results are generally presented in a breath-by-breath format, with predicted values indicated on the display. The advantages and disadvantages of expressing CPET parameters as a function of weight are discussed, with particular reference to obesity
