Final answer:
A CPAP machine can be useful for treating sleep apnea, a sleep disorder characterized by pauses in breathing during sleep.
Step-by-step explanation:
A CPAP machine can be useful for treating sleep apnea. Sleep apnea is a sleep disorder characterized by pauses in breathing during sleep, usually due to physical blockage of the airway. CPAP machines work by pumping pressurized air into the airway to keep it open and allow for normal ventilation. Other treatment options for sleep apnea include lifestyle changes, such as weight loss and avoiding alcohol, as well as surgery in severe cases.
