Abstract

Several studies have shown a favorable effect of continuous positive airway pressure to reduce mortality and the orotracheal intubation need in patients requiring mechanical ventilation. In a Boussignac's valve, pressure is generated when a gas (oxygen or air) passes through a device containing a set of microchannels  causing an acceleration of gas molecules that results in a turbulence due to the so-called "jet effect".

Its use has gradually widened in recent years in emergency departments, resuscitation units and hospital wards.

The use of the valve as a method for non-invasive mechanical ventilation, its handling, suitable candidates for such a therapy, as well as complications and contra-indications, and caring needs from a nursing point of view are described.
