一个新的口内氧计在低氧症期间准确测量动脉氧和度 (SpO2). 这种设备为长期的睡眠呼吸暂停监测提供了潜力.
科学领域:
- 生物医学工程 生物医学工程
- 医疗器械 医疗器械
- 生理监测 生理监测
背景情况:
- 对睡眠呼吸暂停和肺部疾病患者来说,对动脉氧红蛋白和 (SaO2) 监测至关重要.
- 当前的氧度测量解决方案往往不是个性化或适合延长的多夜监测.
- 缺乏易于获得的,长期的SpO2监测设备阻碍了有效的患者管理.
研究的目的:
- 开发和评估一个定制的口腔粘膜口内氧计,用于准确的,长期的SpO2监测.
- 为了评估氧计在一系列临床相关的低氧度水平的性能.
- 为患有睡眠诱导低氧血症的患者提供个性化的监测解决方案.
主要方法:
- 一个反射脉冲氧计被封装在牙上层内,用于口腔内放置.
- 在诱导低氧条件下,在12名参与者身上测试了准确性,与CO-oximeter (黄金标准) 相比.
- 同时测量脉率和心电图衍生的心率也进行了比较.
主要成果:
- 与黄金标准相比,口内氧计在测量SpO2 (r=0.95,A_RMS=2.94%) 中表现出非常高的准确性.
- 脉冲率测量也显示了高准确度 (r=0.99,A_RMS=2.08 bpm). 脉冲率测量也显示了高准确度 (r=0.99,A_RMS=2.08 bpm). 脉冲率测量也显示了高准确度 (r=0.99,A_RMS=2.08 bpm).
- 该设备在广泛的动脉低氧症中可靠地执行.
结论:
- 口腔粘膜氧度仪在测量SPO2和脉冲率方面表现出强大且在临床上可接受的准确性.
- 这种新型设备对睡眠诱导的低氧症患者的SaO2长期监测有希望.
- 口腔内氧计可以成为管理呼吸系统疾病的宝贵工具,这些疾病会影响睡眠期间的氧气水平.
