MOT 133 Cardiovasc
Cardiovascular - Dx & testing
| Question | Answer |
|---|---|
| Allen Test | a measurement of radial or ulnar patency; either the radial or ulnar artery is digitally compressed by the examiner after blood has been forced out of the hand by clenching it into a fist; failure of the blood to diffuse into the hand when opened.... |
| Angiogram | radiography of arteries after the injection of a rediopaque contrast material |
| Arterial Blood Gas | the direct electrode measurement of the partial pressure of oxygen & carbon dioxide in the blood as well as pH and chloride levels |
| Bone Marrow Biopsy | Process of removing bone marrow from living patinets for macroscopic Dx & examination |
| Cardiac Catherization | procedure where a catheter is passed into the heart through a vein or artery, to withdraw samples of blood, measure pressures within the heart's chambers or great vessels & inject contrast media; used for Dx & eval of congential, rheumatic... |
| Cardiac Isoenzymes | chemicals that catalyze the same reaction but may be differentiated by variations in physical properties, such as isoelectric point, electrophoretic mobility, kinetic parameters or modes of regulation. CPK, LDG, AST, Troponin |
| Cardiac Stress Test | use of a tredmill on a patient while connected to a cardiac event monitor to measure cardiac ativity while the body is under physical activity |
| Clotting Studies | tests used to determine the speed of the various plasma components involved in the clotting process. PT, PTT Factor VIII assay, platelet count, fibrinogen levels |
| Doppler | a Dx instrument that emits an ultrasonic beam into the body; the ultrasound reflected from moving structures changes its frequency. Of Dx value in peripheral vascular & cardiac disease |
| Electrocardiogram | graphic record of cardiac action |
| Echocardiogram | the use of ultrasound in the investigation of the structure & motion of the heart and great vessels & Dx of cardiovascular lesions |
| Erythocytic 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 wavelenghts of light |
| Sphygmomanometer | an instrument for measureing arterial blood pressure indirectly, consisting of an inflatable cuff, inflating bulb, & a gauge showing the blood pressure |
| Transesophageal Echo | recording of the echocardiogram from a swallowed transmitter |
| Ultrasonography | the location, measurement, or delineation of deep structures by measuring the reflection or transmission of high-frequency or ultrasonic waves. computer calculation of the distance to the sound-reflecting or absorbing surface plus 2D image |
| Venogram | radiograph of opacified veins |
