CPAP therapy, which stands for Continuous Positive Airway Pressure therapy, is specifically designed to treat obstructive sleep apnea (OSA). This condition is characterized by repeated interruptions in breathing during sleep due to the physical blockage of the airway, often caused by the relaxation of throat muscles and tissues.

The therapy involves the use of a CPAP machine that delivers a constant stream of air through a mask that the patient wears while sleeping. This continuous airflow helps to keep the airway open, preventing apneas (pauses in breathing) and hypopneas (shallow breathing), ultimately improving the quality of sleep and reducing related daytime symptoms such as fatigue, irritability, and cognitive issues.

The other options describe incorrect or misleading concepts. "Constant Partial Airflow Pressure therapy" and "Cardiovascular Pressure Airways Prevention therapy" do not represent recognized therapies in the management of sleep disorders. Additionally, while the statement regarding "Constant Positive Airway Pressure therapy for central sleep apnea" implies a type of sleep apnea treatment, CPAP is primarily indicated for obstructive sleep apnea, and other treatment modalities may be needed for central sleep apnea.
