Algorithm analyzes head movements to measure heart rate

http://web.mit.edu/newsoffice/2013/seeing-the-human-pulse-0620.html MIT researchers have developed an algorithm that gauges heart rate by measuring tiny head movements in video data.  A subject’s heart rate was consistently measured within a few beats per minute when compared to results from electrocardiograms. The algorithm was also able to provide estimates of time intervals between beats, which can be used to identify […]

Machine learning in the ICU

http://www.technologyreview.com/news/515461/machine-learning-and-risk-prediction-in-the-icu/ Etiometry is building a clinical-decision support system to interpret large volumes of real-time patient data and guide diagnosis and treatment.  It integrates and analyzes information from heart monitors, ventilators, and pressure sensors and plugs the data into predictive models that have been built on prior patient outcomes.

Medical device data shared via ultrasound, real-time treatment enabled

http://www.buffalo.edu/news/releases/2013/05/0570.html Navy sonar technology is being miniaturized by University at Buffalo professor Tommaso Melodia to be applied inside the human body to treat diseases like diabetes and heart failure in real time. A network of wireless body sensors that use ultrasounds could be used to wirelessly share information between medical devices implanted in or worn by diabetic/heart failure patients. Previously, researchers focused […]

Flexible “skin” heart monitor

Stanford professor Zhenan Bao has developed a flexible, skin-like heart monitor, worn under an adhesive bandage on the wrist.  This non-invasive method could replace intravascular catheters, which create a high risk of infection, making them impractical for newborns and high-risk patients.  An external monitor could give doctors a safer way to gather information about the heart, especially […]

Medical monitoring via webcam

http://www.economist.com/blogs/babbage/2013/03/remote-monitoring A team of researchers at Xerox is working on technology that would allow doctors to obtain patients’ vital signs using a simple webcam. Already, the team is testing use of the technology to monitor the pulse rate of premature babies and to track irregular heartbeats in patients suffering from arrhythmia. By applying further signal-processing […]

Fujitsu facial imaging technology measures pulse

http://www.sys-con.com/node/2582171 A Fujitsu research lab has developed software that can accurately measure a subject’s pulse using the small digital cameras attached to smartphones and tablets. The technology is based on the fact that the brightness of an individual’s face changes slightly as their heart beats, due to their blood flow. Hemoglobin, which carries oxygen around […]

A move toward aggregating health data from various devices and apps

http://gigaom.com/2013/03/15/tictrac-emerges-to-help-make-health-tracking-more-mainstream/ It seems that every day a new app or device promising the ultimate in health or fitness monitoring enters the market.  A startup has created a personal analytics dashboard which gives people a big picture view of their own aggregated data and underlying patterns, helping them make sense of the numbers.

Doctors use smartphones to save lives

http://appleinsider.com/articles/13/01/25/doctors-see-apples-iphone-as-life-saver-in-the-future-of-medicine A doctor recently used his iPhone, in combination with AliveCor, a mounted sensor capable of delivering clinically accurate electrocardiograms, while in flight, to measure the vital signs of a passenger experiencing severe chest pains at 30,000 feet. The results indicated that the passenger was having a heart attack.  The doctor recommended an urgent landing, […]
