The three major acute disorders which can underly ARF are (ventilator-assisted) pneumonia (VAP), acute respiratory distress syndrome (ARDS) and pulmonary embolism. Each of these conditions poses its own diagnostic and treatment difficulties. This article will review diagnostic procedures relating to these most relevant causes of this syndrome.
