Lung Ultrasound in Critically Ill Patients / 대한구급학회지

ABSTRACT

Lung ultrasound (LUS) is an emerging tool for intensivists to diagnose and monitor thoracic diseases of critically ill patients. It is easily applied at the bedside in real time and is free of radiation hazards. In the intensive care units (ICUs) lung ultrasound can be used to diagnose pneumothorax and interstitial syndrome. It can also be used to monitor changes in the lung. However, the major limitations of LUS is that it is highly operator dependent and cannot be applied in patients with thoracic dressings, subcutaenous emphysema or pleural calcifications. This article reviews the basic principles of lung ultrasound and discusses how it can be used in ICUs.
