Treatment of Obstructive Sleep Apnea

Primary Treatment Algorithm

The American College of Physicians recommends continuous positive airway pressure (CPAP) as the first-line treatment for all patients diagnosed with obstructive sleep apnea (OSA), regardless of severity, with moderate-quality evidence showing it improves symptoms, normalizes traffic accident risk, reduces sympathetic activity, decreases cardiovascular morbidities, and normalizes mortality in severe OSA 1, 2, 4
CPAP or automatic positive airway pressure (APAP) are equally effective and should be prescribed as the primary treatment option for OSA, with patients recommended to use CPAP for the entirety of their sleep period, though even partial use provides benefits 1, 3, 4
Nasal or intranasal masks are preferred over oronasal masks to minimize side effects and maintain efficacy, and heated humidification should be used with CPAP devices to reduce dry mouth/throat, nasal congestion, and nosebleeds 3
Educational interventions at CPAP initiation improve adherence, and all overweight and obese patients with OSA must be encouraged to lose weight as obesity is the primary modifiable risk factor, despite low-quality evidence 1, 2, 3, 5

Mandibular advancement devices (MADs) are recommended as an alternative therapy for patients who prefer them or experience CPAP adverse effects, with evidence supporting MAD use in mild to moderate OSA, but they are less effective for severe OSA 1, 2, 4, 5
Hypoglossal nerve stimulation should be considered for patients with AHI 15-65/h and BMI <32 kg/m² who cannot adhere to PAP therapy, representing a newer option for select CPAP-intolerant patients 3
Maxillomandibular advancement surgery appears as efficient as CPAP in patients who refuse conservative treatment, and should be considered for severe OSA patients who cannot tolerate or are not appropriate candidates for other recommended therapies 3, 4

Positional therapy is clearly inferior to CPAP with poor long-term compliance, and drugs, nasal dilators, and apnea-triggered muscle stimulation cannot be recommended as effective OSA treatments 3, 4, 5
Oxygen therapy is not recommended as stand-alone treatment, and pharmacologic agents lack sufficient evidence and should not be prescribed for OSA treatment 3, 5

Adequate follow-up with troubleshooting and monitoring of objective efficacy and usage data is essential following PAP therapy initiation, and address adherence issues proactively with education, mask adjustments, and humidification before abandoning CPAP 1, 3
