[Haemodynamic changes during artificial ventilation with and without positive end-expiratory pressure in respiratory insufficiency (author's transl)]. 1978

K Geiger

Artificial ventilation with positive end-expiratory pressure (PEEP) affects the haemodynamic function of the various organs differently. Depending on intravascular volume, myocardial contractility and the pulmonary vasculature PEEP ventilation may result in a reduced cardiac output. By increasing the circulating blood volume the cardiovascular changes induced by PEEP can be minimized. When PEEP ventilation is stopped symptoms of hypervolaemia may appear. The effects of PEEP ventilation on the brain, liver, mesenterial circulation and kidney manifest themselves in a rise of intracranial pressure, reduced portal bloodflow, increased mesenteric vascular resistance and redistribution of the intrarenal blood flow respectively.

D011175 Positive-Pressure Respiration A method of mechanical ventilation in which pressure is maintained to increase the volume of gas remaining in the lungs at the end of expiration, thus reducing the shunting of blood through the lungs and improving gas exchange.

D012121 Respiration, Artificial Any method of artificial breathing that employs mechanical or non-mechanical means to force the air into and out of the lungs. Artificial respiration or ventilation is used in individuals who have stopped breathing or have RESPIRATORY INSUFFICIENCY to increase their intake of oxygen (O2) and excretion of carbon dioxide (CO2).
