Part Descriptions

LP19466-9   Cardiac output
Cardiac output is the volume of blood pumped by the heart in one minute and is expressed as a volume rate (L/min). This is in contrast to stroke volume, which is the volume of blood pumped by the heart during one beat. The cardiac output index is the cardiac output normalized for body surface area and is expressed as a volume rate per area (L/min/m2). Source: Regenstrief LOINC

LP6581-5   US.2D.left ventricular outflow tract.calculated
Two-dimensional (2D) imaging is one of three ultrasound modes (2D, M-mode, and Doppler) used for cardiac imaging. 2D imaging is the primary method of cardiac imaging and allows structures to be viewed moving in real time in a cross-section of the heart (two dimensions). It is used to detect abnormal anatomy or motion. The most common cross-sectional views are the parasternal long axis, the parasternal short axis, and the apical view. The gastric or subcostal and suprasternal views are also commonly used. [NCBI Books: NBK2215] Source: Regenstrief LOINC , NCBI Books: NBK2215
