The Equipment CPAP consists of a blower unit, a mask, gear to hold the mask on, and a tube to connect the blower to the mask. A mask that covers only the nose, nasal pillows that fit into the nostrils and on occasion a full face mask that covers the nose and the mouth. For most patients the nose mask is the most comfortable.
Sizes vary from large to petite and from wide to narrow.
Nasal pillows are more comfortable for some but may cause problems at higher pressures because the air blows directly into the nose. Nasal pillows also come in different sizes and must be turned correctly to fit the shape of the nostril. A number of different styles of masks area available, making proper fit for individuals likely. Several different companies make CPAP machines. They all work on the principle that positive pressure holds the upper airway open.
