Oxygen deprivation can cause serious complications and brain damage in newborns, and sometimes it is fatal. Known as hypoxic ischemic encephalopathy, this oxygen deprivation can arise from pregnancy complications such as a twisted umbilical cord and from birth injury suffered during delivery. Approximately 50 percent of newborns developing this condition do not survive, and the remaining newborns frequently suffer from cerebral palsy and other forms of brain damage.The effects of hypoxic ischemic encephalopathy can be reduced by cooling techniques that reduce the newborn's core body temperature. The cost of providing this cooling care has been too expensive or unavailable for medical practitioners in poor, developing or remote areas of the world. In these areas, medical professionals have resorted to the use of fans, cold water bottles and other rudimentary techniques to achieve the extended cooling necessary to save lives and reduce brain damage.
