Effect of hyperoxygenation for one and two minutes on PH, Pao2, Paco2, O2sat during endetracheal suctioning in patient under mechanical ventilation in ICU in Zanjan Vali-e-Asr hospital 2011

Abstract:Background and objective: Endotracheal suctioning (ETS) is a inevitable procedure in patient under mechanical ventilation. The most important complication of this procedure is hypoxemia. The aim of this study is effect of hyperoxygenation for one and two minutes on hypoxemia during ETS. This study is a clinical trial on 30 patients under mechanical ventilation in ICU of Vali-e-Asr hospital in Zanjan. The samples are selected based on study criteria. Finding show that in comparison two long of time hyperoxygenation for one and two minute during ETS has not meaningful effect on O2sat and Pao2 but it sause meaningful effect on PH and Paco2. This recommended for best use of time and cost and to prevent hyperoxygenation complication.
