From the Research

CPAP therapy is the most effective treatment for reducing mortality risk in patients with Obstructive Sleep Apnea (OSA), as it can decrease the risk of death by approximately 30-40% in OSA patients who adhere to therapy. The use of CPAP has been consistently shown to improve outcomes in patients with OSA, including reducing the risk of cardiovascular disease, hypertension, and metabolic dysfunction 1. According to the most recent evidence, CPAP is recommended as the first-line therapy for patients with OSA to improve excessive daytime sleepiness (EDS) 1.

Some key points to consider when implementing CPAP therapy include:

  • Proper mask fitting and gradual pressure adjustment to ensure patient comfort and adherence to treatment
  • Regular equipment maintenance to ensure optimal functioning of the CPAP machine
  • Encouraging patients to use their CPAP machine for at least 4 hours per night on 70% of nights, though greater benefits occur with longer usage
  • Monitoring patients for any comfort issues or side effects and addressing them promptly to ensure consistent CPAP use and maximize its life-saving benefits

It's also important to note that while other treatments, such as oral appliances and surgical interventions, may be effective for some patients with OSA, CPAP remains the most widely recommended and effective treatment for reducing mortality risk in patients with OSA 2, 3, 4. Overall, the evidence suggests that CPAP therapy is a crucial component of OSA management and can significantly improve outcomes in patients with this condition.
