This pillow helps CPAP users feel more comfortable using their equipment and helps to prevent mask leaks and soreness. Sleep apnea refers to a temporary cessation of breath during sleep. Patients with sleep apnea often report chronic headaches, drowsiness, memory lapses, and dysfunction during daily activities. Sleep apnea occurs when a patient's airwaybecomes blocked during sleep by relaxed throat muscles, excess weight, enlarged tonsils, or a very small throat. There is no known cure for sleep apnea, but it is highly treatable with CPAP.
