摘　　要：本研究观察了应用常规操作、高度氧合、通气过度、高度氧合＋通气过度等４种吸痰法对２５例心脏术后患者动脉血氧的影响。经统计学检验，常规吸痰法与通气过度法相比、高度氧合法与高度氧合十通气过度法相比差异均无显著性意义（Ｐ＞０．０５）；常规吸痰法与高度氧合法以及与高度氧合＋通气过度法相比差异均有极显著意义（Ｐ＜０．０１）。结论：吸痰前给予１００％氧气通气１ｍｉｎ，可避免患者由于吸痰所致的血氧降低。In this research,effects on arterial oxygenation for 25 post-cardiac operative patients by common suctioning,hyperoxygenation,hyperventilation and hyperoxygenation with hyperventilation were investiga-ted By statistical analysis,no obvious differences(P>0.05)between comrnon suctioning and hyperventi-lation and between hyperoxygenation and hyperoxygenation with hyperventilation were found,but there were great differences between comrnon suctioning and hyperoxygenation and between common suctioning and hy-peroxygenation with hyperventilation(P<0.01).Conclusion:Hypoxemia caused by suctioning may be pre-vented by 1 minute 100%oxygen ventilation before suctioning.
