Classification of Shock in the Intensive Care Unit Using Transesophageal Two-Dimensional Echocardiography
Shock in the Intensive Care Unit (ICU) is an emergency situation that needs rapid determination of the cause, allowing therapeutic measures. Assessment of the hemodynamic profile using a balloon-tipped floating pulmonary artery catheter usually provides information about the degree of circulatory impairment, which can be used to direct therapy [1–3]. If the hemodynamic variables are non-conclusive and measures taken accordingly do not reverse this clinical emergency, additional information is warranted to ascertain whether shock is distributive (as in sepsis), obstructive (as in cardiac tamponade), hypovolemic (e.g. due to bleeding) or cardiogenic (e.g. myocardial infarction) .
