Y1 - 2015 N1 - T2 - Critical Care Ultrasonography, 2e AB - Left ventricular (LV) dysfunctions (systolic and diastolic) are common in the critically ill patient. They may be due to preexistent disease (e.g., coronary artery disease [CAD]) or acquired as a part of a clinical syndrome responsible for the intensive care unit (ICU) admission (e.g., septic cardiomyopathy). Clinical examination alone or in combination with chest radiography may be insufficient for assessing LV function in the ICU. Echocardiography will provide crucial information; thus, echocardiographic assessment of LV function is necessary in nearly all ICU patients. Other technologies, such as bioreatance (NICOM) and thermo or marker dilution (LiCO, PICO), may provide additional information that can also be useful. Indwelling Doppler devices assessing aortic blood flow have been utilized with variable degree of success. Finally, carotid artery blood flow measured ultrasonographically has been recently suggested as an alternative to more technically challenging analysis of the transaortic stroke volume (SV) (cardiac output [CO]). All of these methods assist in assessing the LV. SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/03/28 UR - accessanesthesiology.mhmedical.com/content.aspx?aid=1125015471 ER -
