Several image-based technologies have been explored for vital signs monitoring, and it is our aim to provide a summary of their current availability and performance.
We aim to review non-contact, non-invasive image/video-based vital signs monitoring devices in health care and health-related fields.
Initial screening process will select any literature reviews to ensure all original studies are included.
Only human subject studies will be included, and no age limits will be set.
The primary goal is to summarise current image-based vital signs monitoring methods, limited to heart rate, respiratory rate, oxygen saturations and blood pressure.
Of particular interest will be the effectiveness of image-based methods compared to reference devices.Examples of their limitations include the following: Some of these limitations and complications may be avoided by using non-contact, non-invasive monitoring methods in the form of image/video-based monitoring.There is a huge potential for this type of monitoring in the current era of telemedicine, and the required technology has developed rapidly in the last decade.This proposed systematic review has been registered with PROSPERO (the International prospective register of systematic reviews): CRD42016029167.All papers looking at monitoring of HR, BP, RR or Sp O using image analysis with comparison to a clinically validated reference device will be included without limitation on the setting.Studies using projected markers but require image/video analysis for monitoring purposes will be included.No limitations will be set on the primary objective of the studies; for example, studies aiming to refine image analysis will be included as long as they measure one of the specified vital signs and compare it to a clinically validated reference device as part of the methodology.Date and language restrictions will not be applied.Authors of studies published in languages other than English will be contacted by email for assistance with data extraction.We will undertake a systematic review of still and video image-based monitoring methods.We will perform searches in multiple databases which include MEDLINE, Embase, CINAHL, Cochrane library, IEEE Xplore and ACM Digital Library.
