背景：目前，新生儿重症监护室使用接触式传感器监测心率：心电图或脉搏血氧饱和度。这些技术可能会导致受伤和感染，特别是对于皮肤脆弱的早产儿。基于摄像头的体积描记法最近在成人中被证明是一种确定心率的非接触式方法。目的：研究该技术对 NICU 患者的可行性并确定具有挑战性的条件。研究设计和参与者：仅使用环境光对加利福尼亚和荷兰两个 NICU 的 19 名婴儿进行视频记录。心率可以从这些记录中得出，因为每个心血管脉冲波都会引起微小的脉动皮肤颜色变化，肉眼看不见，但可以用相机测量。结果：在所有婴儿中，心跳引起的光电体积描记信号足够强，可以测量。低环境光水平和婴儿运动有时会妨碍成功测量。结论：使用环境光通过摄像头进行非接触式心率监测首次在 NICU 人群中得到证实，并且似乎是可行的。需要更好的硬件和改进的算法来提高鲁棒性。 (C) 2013 Elsevier Ireland Ltd. 保留所有权利。
Background: Presently the heart rate is monitored in the Neonatal Intensive Care Unit with contact sensors: electrocardiogram or pulse oximetry. These techniques can cause injuries and infections, particularly in very premature infants with fragile skin. Camera based plethysmography was recently demonstrated in adults as a contactless method to determine heart rate.Aim: To investigate the feasibility of this technique for NICU patients and identify challenging conditions.Study design and participants: Video recordings using only ambient light were made of 19 infants at two NICUs in California and The Netherlands. Heart rate can be derived from these recordings because each cardiovascular pulse wave induces minute pulsatile skin color changes, invisible to the eye but measurable with a camera.Results: In all infants the heart beat induced photoplethysmographic signal was strong enough to be measured. Low ambient light level and infant motion prevented successful measurement from time to time.Conclusions: Contactless heart rate monitoring by means of a camera using ambient light was demonstrated for the first time in the NICU population and appears feasible. Better hardware and improved algorithms are required to increase robustness. (C) 2013 Elsevier Ireland Ltd. All rights reserved.
