The article presents the results of a study of oxygen consumption (OC) during physical activity in patients with lung cancer. We noted that the OC was almost the same in all subjects at rest. During cardiorespiratory exercise testing, patients aged 50–60 years showed a more significant increase in OC when working in aerobic and anaerobic conditions, compared to the older age group, with identical load times. Despite the fact that anaerobic conditions, regardless of age, significantly reduced OC and limited performance, the achievement of the anaerobic threshold in the older age group occurred at lower load capacities. In addition, they had significantly less OC at the anaerobic threshold and peak load. Since a decrease in OC in surgery is associated with a significant increase in postoperative mortality from various causes, ergospirometry in patients is necessary to address the question of the patient's readiness for surgery. This indicator may form the basis for stratifying the risks of adverse events, which requires additional research.
