Exercise-induced arterial hypoxemia.
Exercise-induced arterial hypoxemia (EIAH) at or near sea level is now recognized to occur in a significant number of fit, healthy subjects of both genders and of varying ages. Our review aims to define EIAH and to critically analyze what we currently understand, and do not understand, about its underlying mechanisms and its consequences to exercise performance. Based on the effects on maximal ...
متن کاملExercise effects on erythrocyte deformability in exercise-induced arterial hypoxemia.
Exercise-induced arterial hypoxemia (EIAH) is often found in endurance-trained subjects at high exercise intensity. The role of erythrocyte deformability (ED) in EIAH has been scarcely explored. We aimed to explore the role of erythrocyte properties and lactate accumulation in the response of ED in EIAH. ED was determined in 10 sedentary and in 16 trained subjects, both before and after a maxim...
متن کاملHydration during intense exercise training.
Hydration status has profound effects on both physical and mental performance, and sports performance is thus critically affected. Both overhydration and underhydration - if sufficiently severe - will impair performance and pose a risk to health. Athletes may begin exercise in a hypohydrated state as a result of incomplete recovery from water loss induced in order to achieve a specific body mas...
متن کاملPulmonary gas exchange during exercise in highly trained cyclists with arterial hypoxemia.
The causes of exercise-induced hypoxemia (EIH) remain unclear. We studied the mechanisms of EIH in highly trained cyclists. Five subjects had no significant change from resting arterial PO(2) (Pa(O(2)); 92.1 +/- 2.6 Torr) during maximal exercise (C), and seven subjects (E) had a >10-Torr reduction in Pa(O(2)) (81.7 +/- 4.5 Torr). Later, they were studied at rest and during various exercise inte...
متن کاملArterial Oxygenation and Management of Hypoxemia During VATS
The volume and complexity of thoracic procedures performed with a thoracoscopic approach are steadily increasing. Surgical exposure is paramount for thoracoscopic procedures and requires meticulous lung isolation. In this review, the physiological adaptive mechanisms that occur during one-lung ventilation (OLV) are discussed. Factors that predict the occurrence of hypoxemia during OLV and a str...
