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, […]

NASA technology benefits cardio-pulmonary patients

http://www.azosensors.com/news.aspx?newsID=5350 PUMA measures six components to evaluate metabolic function: oxygen and carbon dioxide partial pressure, volume flow rate, heart rate, and gas pressure and temperature. From those measurements, PUMA can compute the oxygen uptake, carbon dioxide output and minute ventilation (average expired gas flow rate). A small, embedded computer takes readings of each sensor and relays […]

Genetically modified virus produces heart’s own pacemaker in animals

http://technorati.com/technology/article/viruses-helped-to-make-the-natural/ Researchers at the Cedars-Sinai Heart Institute had another idea. They knew a gene called Tbx18 is normally activated during the sinoatrial node’s development, when an embryo is forming. So they set out to add Tbx18 into a functioning, fully grown heart. To do it, they inserted the code for this gene into a virus, […]
