Background:

the use of the airway intubation devices in the critical patient with mechanic ventilation in a Unit of Intensive Cares is related to survival.

Objective:

to evaluate the oxygenation prognosis factors in critical patients with the airway intubation devices.

Methods:

analytic prospective study was carried outin critical patients with airway devices admitted to the Intensive Care Unit of the University Hospital Manuel Ascunce Domenech. The universe was constituted with 1039 patients and the sample by 526 patients, of them 314 alive and 212 deceased through simple random sampling.

Results:

the shock was the main diagnosis that motivated the use of airway adjuncts.It was two times more probable that a critical patient with orotracheal intubation had an inadequate oxygenation state than one critical patient with tracheostomy.

Conclusions:

most of the patients enter with the diagnosis of shock. The oxygenation prognosis factors in the critical patients with airway intubation devices that were associated are: arterial pressure of oxygen, total concentration of oxygen, P50, Px, tracheostomy and orotracheal intubation. More than half of the patients withdrew in live condition.
