The earliest description of a body ventilator was that of a tank-type negative pressure device by the Scottish physician John Dalziel in 1838 ( 1). The earliest noninvasive ventilators were the “body” ventilators, so-called because they assist ventilation by applying negative or positive pressure to various regions of the body. Review articles and consensus statements were also examined and recommendations synthesized into general guidelines.

Bibliographies of articles were also searched for relevant articles. A computerized MEDLINE search from 1966 through June 2000 was undertaken using search terms including mechanical ventilation, intermittent positive pressure ventilation, negative pressure ventilation, respiratory insufficiency/failure, lung disease/obstructive, and lung disease/ restrictive. This review is based on an evaluation of the literature using a multimethod approach. The discussion will consider the rationale for use, currently available techniques and equipment, evidence for efficacy, selection of appropriate patients, and general guidelines for application, monitoring, and avoidance of complications. The following will explore these trends in the use of noninvasive ventilation and then provide a current perspective on applications in patients with acute and chronic respiratory failure. The past decade has seen a resurgence in the use of noninvasive ventilation, largely because of the development of nasal ventilation, which has the potential of providing ventilatory assistance with greater convenience, comfort, safety, and less cost than invasive ventilation. via an endotracheal tube) positive pressure ventilation superceded negative pressure ventilation, primarily because of better airway protection. During the first half of the 20th century, negative pressure types of noninvasive ventilation were the main means of providing mechanical ventilatory assistance outside of the anesthesia suite. Noninvasive ventilation refers to the delivery of mechanical ventilation to the lungs using techniques that do not require an endotracheal airway.
