Abstract:
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.
