Abstract
The reaction of cerebral blood flow during breathing with positive end expiratory pressure in elderly people with physiological (24 pers.) and accelerated (26 pers.) aging of the respiratory system were studied. It is shown that in people with accelerated aging of the respiratory system some resistance to expiration improves the efficiency of gas exchange in the lungs. However, breathing with considerable resistance to expiration (15 mm water column) in people with accelerated aging of the respiratory system, causing depression of gas exchange in the lungs. Found that people with accelerated aging of the respiratory system decreased pulmonary gas ex-change response to breathing resistance expiration.
Keywords:
positive end expiratory pressure, pulmonary gasexchange, accelerated aging.
