对105例肺炎患儿进行了无创性脉搏血氧饱和度仪(Pulse oximeter)检(监)测血氧饱和度(SpO_2),并对其中20例重症患儿同时作动脉血氧饱和度(SaO_2)测定。结果:SpO_2与SaO_2密切相关,用SpO_2求SaO_2的回归方程为:Y=0.15+0.82X(r=0.93)。结论:Pulse oximeter对立即判断肺炎患儿的缺氧程度和氧合情况具有较高的实用价值,能早期发现和诊断低氧血症;能帮助调整氧流量,指导氧疗。另外,还对Pulseoximeter使用中的局限性作了说明。
In 105 children with pneumonia, the noninvasive pulse oximeter was used to monitor the oxygen saturation (SpO_2), and the arterial oxygen saturation (SaO_2 ). Results: SpO_2 was closely related to SaO_2, and the regression equation of SaO_2 with SpO_2 was: Y = 0.15 + 0.82X (r = 0.93). Conclusion: The measurement of oxygen deficiency and oxygenation in children with pneumonia is of great practical value. It can detect and diagnose hypoxemia early. It can help to adjust oxygen flow and guide oxygen therapy. In addition, the limitations of using the Pulseoximeter are described.
