Simple device can help babies with tragic heart flaw
A new cheap device could help monitor blood oxygen
levels in babies caused by congenital heart defects. Thirteen new studies which
included almost 230,000 neonatal children were testing this new device. The
device works by comparing the differences in red light, which is
absorbed by oxygenated blood and infrared light, which is absorbed by
deoxygenated blood. The device is called a Pulse Oximetry which detected 76.6%
of congenital heart defects and had a rate of just 0.14 percent of "false
positives," a term meaning the times when the device wrongly signaled a
problem when in fact the infant was healthy. This device could be a life saver
for many children in the future and is a useful non invasive early warning
system for doctors to use.
