Pulmonary artery pressure and lung water during extracorporeal circulation in experimental pulmonary insufficiency. 1975

B Brandt, and B Doyle, and H Weintraub, and H Harrison

Use of the membrane oxggenator has been advocated in the management of severe respiratory insufficiency. We have compared this method to conventional therapy in an experimental model in which 23 dogs were subjected to aspiration with 0.1 N HC1 and 18 were supported with a volume respirator and positive end-expiratory pressure or placed on partial bypass using a membrane oxygenator for 12 to 24 hours. Adequate oxygenation (POX greater than 100 mm Hg) was achieved with the membrane oxygenator. The increase in lung weight during conventional therapy was significantly greater than during membrane oxygenator support. Extracorporeal support during recovery from severe pulmonary injury allows pulmonary artery pressure to be controlled and reduces the expected increase in lung water.

UI	MeSH Term	Description	Entries
D008168	Lung	Either of the pair of organs occupying the cavity of the thorax that effect the aeration of the blood.	Lungs
D008170	Lung Compliance	The capability of the LUNGS to distend under pressure as measured by pulmonary volume change per unit pressure change. While not a complete description of the pressure-volume properties of the lung, it is nevertheless useful in practice as a measure of the comparative stiffness of the lung.

D009929	Organ Size	The measurement of an organ in volume, mass, or heaviness.	Organ Volume,Organ Weight,Size, Organ,Weight, Organ
D010100	Oxygen	An element with atomic symbol O, atomic number 8, and atomic weight [15.99903; 15.99977]. It is the most abundant element on earth and essential for respiration.	Dioxygen,Oxygen-16,Oxygen 16
D010107	Oxygenators, Membrane	Devices in which blood and oxygen are separated by a semipermeable membrane, generally of Teflon or polypropylene, across which gas exchange occurs. The membrane may be arranged as a series of parallel plates or as a number of hollow fibers; in the latter arrangement, the blood may flow inside the fibers, which are surrounded by gas, or the blood may flow outside the fibers and the gas inside the fibers.

D010477	Perfusion	Treatment process involving the injection of fluid into an organ or tissue.	Perfusions
D011015	Pneumonia, Aspiration	A type of lung inflammation resulting from the aspiration of food, liquid, or gastric contents into the upper RESPIRATORY TRACT.

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.

D011651	Pulmonary Artery	The short wide vessel arising from the conus arteriosus of the right ventricle and conveying unaerated blood to the lungs.	Arteries, Pulmonary,Artery, Pulmonary,Pulmonary Arteries
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).
