hjärtlungfunktionspåverkan
Heart–lung function, or cardiopulmonary function, refers to the integrated performance of the heart and lungs in delivering oxygen to tissues and removing carbon dioxide. It depends on the heart’s ability to pump blood (cardiac output and stroke volume), the lungs’ capacity to ventilate and exchange gases, and the arterial oxygen content carried by hemoglobin. In Swedish usage, the concept is referred to as hjärt-lungfunktion or hjärtlungfunktion, reflecting the same physiologic integration.
Assessment of heart–lung function involves multiple measures. Cardiac function is described by cardiac output, heart rate,
Normal heart–lung function supports adequate exercise tolerance, organ perfusion, and metabolic demands. Impairment can arise from
Lifestyle factors and training influence function. Regular aerobic exercise can improve VO2 max and ventilatory efficiency,
