Evaluation of hypotension in the intensive care unit (ICU) is aided by transesophageal echocardiography (TEE) to establish volume status, cardiac function, and the presence or absence of hemodynamically significant valvular stenosis or regurgitation. 2D, two-dimensional; BPM, beats per minute; LA, left atrium; LV, left ventricle; Pat. T, patient temperature; RV, right ventricle; TEE T, transesophageal echocardiography temperature.重症监护病房（Intensive Care Unit, ICU）低血压的评估可借助经食管超声心动图（transesophageal echocardiography, TEE）以明确患者的容量状态、心功能，以及是否存在具有血流动力学意义的瓣膜狭窄或反流。其中，2D即二维；BPM为每分钟心跳数（beats per minute）；LA指左心房（left atrium）；LV指左心室（left ventricle）；Pat. T为患者体温；RV指右心室（right ventricle）；TEE T为经食管超声心动图检测温度。
