A bedside clinical and ultrasound-based approach to hemodynamic instability - Part II: bedside ultrasound in hemodynamic shock: Continuing Professional Development

Abstract

Abstract: Shock is defined as a situation where oxygen transport and delivery is inadequate to meet oxygen demand. The patient in shock is evaluated through medical history, physical examination, and careful observation of the hemodynamic and respiratory monitors. The patient is initially managed with basic resuscitation measures, however bedside ultrasound should be performed if hemodynamic instability persists. We propose to use ultrasound of the inferior vena cava (IVC), and the concept of venous return, as the initial step in order to identify the mechanism of shock. Doppler examination of the hepatic venous flow can also be added. Further ultrasound examination of the patient’s heart, t..
