应用无创脉搏氧监测仪（ＰＯＭ）对６４例小儿气管、支气管异物取出术脉搏氧饱和度（ＳｐＯ２）进行连续监测，结果表明：小儿气道异物取出术后，由于麻醉和手术等因素，使５９．４％的患儿存在不同程度的低氧血症。在监护室经吸氧、抗炎等治疗，低氧血症得以纠正。 Sixty-four pediatric patients with tracheobronchial and bronchial foreign bodies were continuously monitored by noninvasive pulse oxygen monitor (POM). The results showed that after the removal of pediatric airway foreign bodies, due to factors such as anesthesia and surgery, .4% of children have varying degrees of hypoxemia. In the care unit by oxygen, anti-inflammatory treatment, hypoxemia can be corrected.
