| 目的 探讨基于成像式光电容积描记 (iPPG）技术的非接触式生命体征监测系统在重症监护室（ICU）重症康复的应用。 方法 选取2021年7月至2021年9月符合入选和排除标准的气管切开患者10例，分别采用基于iPPG技术的非接触式生命体征监测系统和24 h床旁监护仪采集每例患者在静息状态、翻身吸痰、采取重症康复治疗措施如运动治疗、作业治疗时的生命体征参数，包括心率、血氧饱和度和血压（舒张压和收缩压），连续采集3 d。将2种方式采集到的心率、血氧饱和度和血压（舒张压和收缩压）进行比较，分析基于iPPG技术的非接触式生命体征监测系统监测的准确性。 结果 基于iPPG技术的非接触式生命体征监测系统监测的血氧饱和度为（98.56±1.46）%，24 h床旁监护仪记录的血氧饱和度为（98.80±1.35）%，2种采集方式所得数值比较，差异无统计学意义（P>0.05）。非接触式生命体征监测系统监测的心率、舒张压、收缩压分别为（87.54±13.97）次/min、（130.93±11.47）mmHg、（87.43±7.01）mmHg，与24 h床旁监护仪记录的（84.78±11.88）次/min、（126.06±17.81）mmHg、（64.86±13.69）mmHg比较，差异均有统计学意义(P<0.05)。 结论 在重症康复环境中，基于iPPG技术的非接触式生命体征监测系统在血氧饱和度这个生理指标上准确性高，在心率、收缩压、舒张压这三项指标上仍有较大的提升空间。 |

| Objective To explore the application of photoplethysmography (iPPG) for contactless vital signs monitoring in the intensive care unit (ICU). Methods Ten tracheostomy patients in intensive care had their heart rate, oxygen saturation, and diastolic and systolic pressures monitored using iPPG technology and a 24-hour bedside monitor. The readings included periods at rest, during turning, during suctioning, and when undergoing vigorous physical therapy and occupational therapy. The monitoring lasted 3 consecutive days. The data collected by the two methods were compared to analyze the accuracy of the contactless vital signs monitoring system. Results The oxygen saturation readings of the two systems showed no significant differences. The heart rates, diastolic pressures, and systolic pressures did, however, differ significantly. Conclusions In the situations tested, contactless monitoring of oxygen saturation is effective, but there is still significant room for improvement in the three indicators of heart rate, systolic pressure, and diastolic pressure. |
