Why is CPAP therapy commonly necessary for many patients?

CPAP therapy, which stands for Continuous Positive Airway Pressure, is commonly necessary for many patients because it effectively alleviates the symptoms of obstructive sleep apnea (OSA). OSA is characterized by repeated episodes of airway obstruction during sleep, leading to disrupted sleep and multiple health issues, including daytime fatigue, cardiovascular problems, and impaired cognitive function.

The mechanism of CPAP involves the use of a machine that delivers a steady stream of air through a mask, keeping the airway open during sleep. This prevents the collapses that characterize OSA episodes, thus enabling patients to experience uninterrupted sleep. As a result, many patients report significant improvements in sleep quality, daytime alertness, and overall quality of life once they begin CPAP treatment.

The other options do not align with the key purpose or benefits of CPAP therapy. It's important to understand that while cost and invasiveness are factors in patient care, they do not define why CPAP is a necessary treatment. The focus on its effectiveness in treating and managing the symptoms of OSA is what makes it a commonly chosen therapy.
