Mechanical ventilation: past and present

Abstract

Emergency physicians commonly manage patients with acute respiratory failure who require assisted mechanical ventilation. Several different modes of positive pressure mechanical ventilation can be used to manage these patients when they present to the emergency department. These modes of ventilation have evolved over the last three decades. A comprehensive review of the most important historical moments in mechanical ventilation as well as the different modes commonly used in the emergency department are presented. In addition, new techniques in noninvasive mechanical ventilation are presented.
