DESCRIPTION (provided by applicant): There are 3.7 million neonatal deaths and 2.6 million stillbirths in the world each year, and 98% of these occur in developing countries. Some of these deaths are the result of birth attendants not recognizing that unresponsive neonates at birth are alive and can be resuscitated. The goal of this proposed effort is to develop and evaluate a simple instrument, known as a cardiac annunciator that can be placed on a newborn infant's chest to sense its electrocardiogram and produce a sound and a light flash for each detected heart beat. Such a device can help to confirm that the infant is alive and that resuscitation should be attempted. It can also serve to confirm improvement in heart rate as the resuscitation proceeds. The proposed effort is directed at developing the device including electronics, sensing electrodes, and packaging and then to evaluate the device in clinical facilities domestically and in India. Further engineering improvements of the device will be made based upon these evaluations, and if successful the device could be used in a larger clinical study in the developing world to demonstrate its overall impact on reduction of worldwide infant mortality rates. An investigative team of a biomedical engineer, clinical physiologist in India, and neonatologist will ensure that the developed cardiac annunciator will be designed to meet clinical needs of the developing world as well as follow good engineering practices.

描述（申请人提供）：全球每年有 370 万新生儿死亡和 260 万死产，其中 98% 发生在发展中国家。其中一些死亡是由于接生员没有认识到出生时反应迟钝的新生儿还活着并且可以复苏的结果。这项工作的目标是开发和评估一种简单的仪器，称为心脏信号器，可以放置在新生儿的胸部来感知其心电图，并在每次检测到的心跳时发出声音和闪光。这样的设备可以帮助确认婴儿还活着并且应该尝试复苏。它还可以用来确认随着复苏的进行心率的改善。拟议的工作旨在开发该设备，包括电子设备、传感电极和包装，然后在国内和印度的临床设施中评估该设备。将根据这些评估对该设备进行进一步的工程改进，如果成功，该设备可以用于发展中国家的更大规模的临床研究，以证明其对降低全球婴儿死亡率的总体影响。由生物医学工程师、印度临床生理学家和新生儿学家组成的研究小组将确保开发的心脏信号器的设计能够满足发展中国家的临床需求，并遵循良好的工程实践。
