The CPAP machine is made up of three main parts: a mask, a tube, and a blower unit. The mask is fitted over the nose and mouth to deliver the pressure to the throat while you sleep. The tube connects the mask to the blower unit which powers it. The blower unit is usually located near your bed but can also be mounted on ceilings or walls in some cases.
A typical CPAP machine weighs about 4 pounds and can be carried with ease from room to room or home to office depending on where you use it at night.
