Cardiopulmonary Testing for Potential Pancreas Transplant Candidates

"The participant will undergo a cardio-pulmonary exercise test (CPET) on a cycle ergometer (Ergoline) connected to a 12-lead electrocardiogram, oxygen saturation monitor and continuous non-invasive blood pressure cuff. Respiratory gas exchanged will be measured from a tight fitting facemask. An initial 2-min period of baseline data will be collected at rest before a 180-s period of unloaded cycling. A ramp protocol will then be applied and the participant will be instructed to continue cycling at a constant cadence of 60 rpm as long as they can. The test will be terminated if the participant indicates that:~* they cannot continue~* cadence falls to \<55 rpm due to fatigue or dyspnoea~* they develop abnormal cardiac signs or symptoms, such as ischaemia and arrhythmia."
