[摘要] 目的 探讨指夹式测量血氧饱和度纳入入院流程的作用及意义。 方法 选择2016年1～7月我院内二科共收住患者848例，使用指夹式血氧仪常规测量患者血氧饱和度。 结果 传统评估低氧血症准确率82.55%，使用指夹式血氧仪评估低氧血症准确率96.93%，指夹式血氧仪准确率显著高于传统评估方法（P<0.05）；报警处理时间对比方面，应用指夹式血氧仪的处理时间显著少于传统缺氧评估（P<0.05）；误报警发生情况方面，应用指夹式血氧仪的误报警率以及患者不良事件例数均显著少于传统缺氧评估（P<0.05）。 结论 指夹式测量血氧饱和度便于及时发现患者是否存在低氧血症、组织灌注不足等异常情况，对早期筛选血氧饱和度低下的患者具有较高的灵敏度，是一项安全、非侵入性、费用低、可行且合理的检测技术，对疾病的早发现、早治疗起重要的作用，值得临床慢病科室推广使用。

[Abstract] Objective To study the effect and significance of finger clip oximetry of oxygen saturation into admission process. Methods 848 patients admitted in the Ward 2， Department of Internal Medicine from January to July 2016 were enrolled， and the blood oxygen saturation of the newly admitted patients was measured by finger clip oximetry. Results The accuracy rate of hypoxemia was 82.55% by traditional assessment， and the accuracy rate of hypoxemia was 96.93% by finger clip oximetry. The accuracy of finger clip oximetry was significantly higher than that of traditional assessment（P<0.05）. The treatment time of the finger clip oximetry was significantly less than that of the traditional assessment（P<0.05）. In the case of false alarm occurrence， the false alarm rate and the case of adverse events of the finger clip oximetry were lower than those of traditional assessment（P<0.05）. Conclusion Finger clip measurement of oxygen saturation facilitates the timely detection of abnormal situation such as hypoxemia and tissue perfusion in patients， which has a high sensitivity in early screening of patients with low oxygen saturation， and is a safe， non-invasive， low cost， feasible and reasonable detection technology. And it plays an important role in early detection and early treatment of disease. It is worthy of clinical use in the department of chronic diseases.

氧對于人体生命活动而言是必不可少的，缺氧会给机体带来严重影响。在低氧条件下，患者首先会发生心率加快以及心排量上升，同时出现血流的再分配、脑血管以及冠状血管扩张从而保障供血充足[1]。严重低氧条件下，因为心内膜乳酸堆积会诱发心肌抑制，使得患者出现心动过缓问题，心排量以及血压持续下降，威胁患者的生命健康[2]。因此动脉氧浓度监测在临床救护过程当中有重要的价值。我院将指夹式测量血氧饱和度纳入入院流程，现报道如下。

1 资料与方法

1.1 一般资料

2016年1～7月我院内二科共收住患者848例，其中男406例，女442例，年龄27～104岁，平均63岁。罹患疾病：慢性呼吸系统疾病420例，神经系统疾病150例，循环系统疾病150例，消化系统疾病76例，内分泌类疾病35例，其他17例。将患者均分为两组分别进行传统缺氧评估及指夹式血氧仪测量血氧饱和度。患者均知情同意本研究，并经过医院伦理委员会批准。

1.2 方法

1.2.1 传统评估缺氧方法 患者入院后，让其处于安静平卧状态，检测血压、脉搏、呼吸、体温，观察面色、口唇颜色、呼吸运动情况，评估其是否缺氧[3，4]。……
