Randomized Controlled Trial Comparative Study Clinical Trial[Endotracheal aspiration: respirator vs. manual resuscitation as method for hyperoxygenation and hyperinflation].
Endotracheal aspiration protocols (EAT) include hyperoxygenation and hyperinflation to minimize the negative effects of the technique. No conclusive studies have determined the most effective hyperoxygenation and hyperinflation method. This study had two aims: to compare the effects on patient oxygenation and hemodynamics during endotracheal aspiration of secretions using, respectively, a respirator or manual resuscitator as the hyperoxygenation and hyperinflation method. ⋯ Analysis of the effectiveness of the manual resuscitator (the second aim) under the conditions established yielded a mean FIO2 of 0.86 and a mean tidal volume of 153% in relation to baseline tidal volume. Both methods of hyperoxygenation and hyperinflation prevent hypoxia and maintain hemodynamic stability in patients without producing lung damage. The effectiveness of the manual resuscitator for administering high oxygen concentration and large volumes was confirmed.
