Evaluation of cardiovascular function follows international guidelines. Should the metabolic equivalent of task be ≥4 then no further testing is required, but if less than 4 then additional tests are required. In addition to measurement of arterial blood gases and pulse oximetry, the predicted forced expiratory volume in one second and diffusing capacity of the lungs for carbon monoxide should be measured to evaluate risks of lung resection. Renal impairment, obesity, systemic and pulmonary hypertension, and diabetes mellitus all increase the risk of surgery. All team members should assess preoperatively the global risk of surgery to the patient. Where appropriate, input from a cardiologist and/or a respiratory physician is valuable. Finally, identifying high-risk patients makes it easier to plan their strategy. Patients with preoperative organ dysfunction are likely to require planned admission to a critical care area.
