Cardiovascular - blood systems

Allen test A measurement of radial/ulnar patency; either the radial ulnar artery is digitally compressed - blood has been forced out of hand by clenching into fist; failure of blood to diffuse into hand when opened indicates artery not compresed is occluded
Angiogram Radiography of arteries after injection of radiopaque contrast material
Arterial blood gas The direct electrode measurement of partial pressure of oxygen and carbon dioxide in the blood as well as pH and chloride levels
Bone marrow biopsy Process of removing bone marrow from living patients for macroscopic diagnostic examination
Cardiac catherization A procedure where catheter passed into heart through a vein or artery to withdraw samples of blood, measure pressure in heart's chambers or great vessels, inject contrast media, used to diagnose & eval of congenital, rheumatic & coronary artery lesions &
Cardiac isoenzymes Chemicals that catalyze same reaction but may be differentiated by variations in physical properties, such as isoelectric point, electrophoretic mobility, kinetic parameters, or modes of regulation. CPK, LDH, AST, Troponin
Cardiac stress test Use of treadmill on patient while connected to a cardiac event monitor to measure cardiac activity while body is under physical activity
Clotting studies Tests used to determine the speed of various plasma components involved in the clotting process, PT, PTT, Factor VIII assay, platelet count, fibrinogen levels
Doppler A diagnostic instrument that emits an ultrasonic beam into body; the ultrasound reflected from moving structures changes its frequency. Of diagnostic value in peripheral vascular and cardiac disease
Electrocardiogram Graphic record of cardiac action
Echocardiogram The use of ultrasound in the investigation of the structure and motion of the heart and great vessels and diagnosis of cardiovascular lesions
Erythrocytic sedimentation rate The rate of settling of red blood cells in anticoagulated blood; increased rates are often associated with anemia or inflammatory states
Pulse oximetry A spectrophotometric device that noninvasively estimates saturation of arterial oxyhemoglobin (SaO2) by use of selected wavelengths of light
Sphgmomanometer An instrument for measuring arterial blood pressure indirectly, consisting of an inflatable cuff, inflating bulb, and a gauge showing the blood pressure
Transesophageal echo Recording of the echocardiogram from a swallowed transducer
Ultrasonography The location, mesurement, delineation of deep structures by measuring reflection of transmission high-frequency or ultrasonic waves. Computer calculation of the distance to the sound-reflecting or absorbing surface - gives a two-dimensional image
Venogram Radiograph of opacified veins
