To assess the feasibility of using an ordinary digital video camera to measure heart rate and detect oxygen desaturations in healthy infants. Heart rate and oxygen saturation were measured with a video camera by detecting small color changes in 28 infants’ foreheads and compared with standard pulse oximetry measures. Multivariable regression examined the relationship between infant characteristics and heart-rate measurement precision. The average bias of camera heart-rate measures was −4.2… Expand

Non-contact heart rate monitoring utilizing camera photoplethysmography in the neonatal intensive care unit - a pilot study.
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,Expand
Reflectance pulse oximetry in neonates.
TLDR
As a feasible and reliable method of non-invasive oxygen saturation monitoring in neonates, RPOX has potential applications in fetal scalp monitoring. Expand
Calibration of Contactless Pulse Oximetry
TLDR
For healthy adults, the results present strong evidence that camera-based contactless pulse oximetry is fundamentally feasible because long-term error stemming from variation among individuals expressed as A*rms is significantly lower than that required by the International Organization for Standardization standard. Expand
Non-contact video-based vital sign monitoring using ambient light and auto-regressive models.
TLDR
This work has devised a novel method of cancelling out aliased frequency components caused by artificial light flicker, using auto-regressive (AR) modelling and pole cancellation, and has been able to construct accurate maps of the spatial distribution of heart rate and respiratory rate information from the coefficients of the AR model.

Availability and performance of image-based, non-contact methods of monitoring heart rate, blood pressure, respiratory rate, and oxygen saturation: a systematic review.
TLDR
Heart rate and respiratory rate monitoring using images is currently possible and performs within clinically acceptable limits in experimental conditions and camera-derived estimates were less accurate in the proportion of studies in clinical settings. Expand
Non-contact detection of oxygen saturation based on visible light imaging device using ambient light.
TLDR
This is the first demonstration of an accurate video-based method for non-contact oxygen saturation measurements by using ambient light with their respective visible wavelength of 660nm and 520nm which is free from interference of the light in other bands. Expand
Non-contact, automated cardiac pulse measurements using video imaging and blind source separation.
TLDR
This is the first demonstration of a low-cost accurate video-based method for contact-free heart rate measurements that is automated, motion-tolerant and capable of performing concomitant measurements on more than one person at a time. Expand
Development of a baby friendly non-contact method for measuring vital signs: First results of clinical measurements in an open incubator at a neonatal intensive care unit
TLDR
Non-contact monitoring of vital signs has proven to be feasible and can be developed into a real time system and Besides the application on the NICU non-contact vital function monitoring has large potential for other patient groups. Expand
Continuous non-contact vital sign monitoring in neonatal intensive care unit
TLDR
It is shown that continuous estimates of heart rate, respiratory rate and oxygen saturation can be computed with an accuracy which is clinically useful, and the authors have shown that clinically important events such as a bradycardia accompanied by a major desaturation can be identified with their algorithms for processing the video signal.

Early Postnatal Heart Rate Variability in Healthy Newborn Infants
TLDR
The hypothesis that HRV is a good indicator of overall wellbeing of a baby and is sensitive to detect birth-related stress and monitor its resolution over time is supported. Expand
