Somnetics out of New Brighton, MN received European CE marking for its Transcend CPAP (continuous positive airway pressure) sleep apnea system. The device weighs less than a pound (1/2 Kg), making it the world’s smallest CPAP.
The system features a waterless humidification system that employs a disposable hygienic heat moisture exchanger cartridge that doesn’t use any electricity to do its job. It captures moisture and heat from exhaled air as the user breathes out, but releases the carbon dioxide out the vents. Upon breathing in, the cartridge heats and humidifies inhaled air using reserves from the previous breath.
