The resulting symptoms include morning headache, trouble concentrating, forgetfulness, irritability, anxiety. These people may be affected with a disorder called sleep apnea. The statistics shows that 9% of middle-aged males and 4% of middle-aged females are affected with this disorder in US. 1/4 of people who snore are sleep apnea patients. In Japan, about 1% of the population have sleep apnea. PAP is a common medical appliance for treating sleep apnea. The treatment is effective is up to 95%. It delivers a stream of compressed air via a face mask and hose, splints the airway (keeping it open under air pressure) so that unobstructed breathing becomes possible, reducing and/or preventing apneas and hypopneas. The fixed type is powered by wall socket, and the portable type can be powered by wall socket as well as battery. Portable PAP usually used Lead-Acid battery. However, the size is too bulky to build into PAP, so the user has to carry it separately. In addition, because of low energy density, the user has to prepare additional batteries. On the other hand, LiCoO2 battery can't be used under high temperatures because its potential explosion risk. The latest Aleees HIBS battery is high capacity, slim and compact, and it is also functional under various circumstances because of its high safety.
