Description

The measurement of cardiopulmonary vital signs is fundamental to understanding the health status and cognitive capacity of the subject. These measures can give the observer crucial data to enable assessment of general health and fitness, physical and mental stress or fatigue, autonomic function, respiratory distress, or impending cardiac events. Vital signs are typically determined using contact-based sensors which are inappropriate for a number of operational use cases because they are physically restrictive or are overly distracting from the task at hand.Photoplethysmography (PPG) generates physiological response waveforms from contact-based sensors. Using advanced signal processing methods, a large number of physiological parameters may be extracted from these waveforms. Imaging photoplethysmography (iPPG) is a technique whereby similar waveforms may be obtained from remote video images of the subject. InteloMed has commercialized an FDA-cleared PPG analysis device, and is currently developing methods for video-based iPPG analysis. In this project, they will leverage this expertise to develop a complete iPPG analysis pipeline for advanced remote cardiopulmonary vital sign monitoring which may be implemented in a variety of hardware embodiments, as defined by the operational use case. The resulting devices will have commercial applications in telemedicine and remote crew monitoring.
