Cardiopulmonary exercise testing (CPET) is a non-invasive, dynamic assessment of the cardiopulmonary system at rest and during exercise. It provides an objective assessment of an individual’s functional capacity, that is the ability to respond to the increased metabolic demand associated with major surgery. This information can help to estimate the risk of perioperative morbidity and mortality as well as assist clinicians in the decision-making process between surgical and non-surgical management of the patient. The outcome of this preoperative investigation may also inform surgical consent, planning and optimisation of a patient in preparation for their operation.
