The use of point-of-care ultrasound of the heart is becoming more widespread. A variety of users have joined traditional users of cardiac ultrasound, cardiologists, and are imaging their patients in real time at the point of care. Patients with undifferentiated shock, hypotension, chest pain, or dyspnea are ideal candidates for focused cardiac ultrasound (FOCUS). In addition, any patient in whom the diagnosis of pericardial effusion or tamponade, pulmonary embolism, or left ventricular dysfunction is suspected would benefit from FOCUS. Of particular importance is the use of FOCUS to rapidly determine the etiology of cardiac arrest. This review will detail the indications, techniques, and limitations of FOCUS in these patients.
床旁心脏超声的应用正变得越来越广泛。各种使用者加入了心脏超声的传统使用者——心脏病专家的行列，他们在床旁对患者进行实时成像。患有不明原因休克、低血压、胸痛或呼吸困难的患者是聚焦心脏超声（FOCUS）的理想对象。此外，任何疑似心包积液或心包填塞、肺栓塞或左心室功能障碍的患者都将从FOCUS中受益。特别重要的是利用FOCUS快速确定心脏骤停的病因。本综述将详细介绍FOCUS在这些患者中的适应证、技术和局限性。
