A critical review and analysis of the current research on the efficacy of the ventilator versus the manual resuscitation bag (MRB) as the method of delivering hyperoxygenation/hyperinflation breaths before, during, and/or after endotracheal suctioning (ETS) is presented. Current research findings indicate that hyperoxygenation/hyperinflation breaths at 100% oxygen (O2) delivered via the ventilator have resulted in elevated blood-O2 levels which are either superior or equivalent to the MRB in preventing suction-induced hypoxemia. Delivery of hyperoxygenation/hyperinflation breaths using the MRB results in increased airway pressure, and increased hemodynamic consequences. Guidelines of clinical practice, based on current research findings, are presented. Areas for further research are identified.
本文对目前关于在气管内吸痰（ETS）前、期间和/或之后，使用呼吸机与手动复苏袋（MRB）进行高氧/过度通气呼吸的疗效研究进行了批判性综述和分析。目前的研究结果表明，通过呼吸机输送100%氧气（O2）进行高氧/过度通气呼吸，可使血液中的氧气水平升高，在预防吸痰引起的低氧血症方面，其效果优于或等同于MRB。使用MRB进行高氧/过度通气呼吸会导致气道压力增加和血流动力学后果增加。基于目前的研究结果，提出了临床实践指南。确定了进一步研究的领域。
