Pulmonary
101pulmonary capillary wedge pressure — pressure of blood in the left atrium of the heart, which indicates the adequacy of the pulmonary circulation. It is measured using a catheter wedged in the most distal segment of the pulmonary artery. See also Swan Ganz catheter …
102pulmonary alveoli — alveoli pulmonis alveoli of lung: small polyhedral outpouchings along the walls of the alveolar sacs and alveolar ducts; through these walls gas exchange takes place between alveolar gas and pulmonary capillary blood. Alveoli pulmonis (pulmonary… …
103pulmonary atresia — congenital severe narrowing or obstruction of the pulmonary orifice of the heart, characterized by cardiomegaly, reduced pulmonary vascularity, and right ventricular atrophy. It is usually associated with tetralogy of Fallot, transposition of… …
104pulmonary artery banding — an operation to provide constriction of the pulmonary artery with a band to reduce pulmonary blood flow and relieve congestive heart failure in children with congenital heart defects that produce left to right shunts between ventricles or the… …
105pulmonary blastoma — a rare malignant pulmonary neoplasm whose cells resemble those of the fetal pulmonary blastema; it is usually large, develops in the peripheral portions of the lungs, and may invade the bronchi …
106pulmonary artery catheter — any of various cardiac catheters for measuring pulmonary arterial pressures, introduced into the venous system through a large vein and guided by blood flow into the superior vena cava, the right atrium and ventricle, and into the pulmonary… …
107pulmonary congestion — engorgement of the pulmonary vessels, with transudation of fluid into the alveolar and interstitial spaces (pulmonary edema); it occurs in cardiac disease, infections, and certain injuries …
108pulmonary plexus anterior — the smaller portion of the pulmonary plexus, located in front of the root of the lung and interconnected with the posterior pulmonary plexus …
109pulmonary plexus posterior — the larger portion of the pulmonary plexus, located behind the root of the lung and interconnected with the anterior pulmonary plexus …
110pulmonary artery wedge pressure — (PAWP), pulmonary capillary wedge pressure (PCWP) blood pressure measured by a catheter wedged into the distal pulmonary artery; it permits indirect measurement of the mean blood pressure in the left atrium …
