Moderate Sleep Apnea: Treatment Choices at AHI 15–29
At 15 to 29 events per hour, breathing is disrupted every two to four minutes all night — moderate disease where treatment clearly helps and both machines and appliances are on the table. The choice usually turns on symptoms, anatomy, and what you will genuinely use.
Key takeaways
- Moderate OSA carries measurable cardiovascular and daytime-function risk, so guidelines consistently recommend active treatment rather than watchful waiting.
- CPAP remains first-line therapy for moderate disease because it reliably drives the AHI back toward normal when used consistently through the night.
- Custom mandibular advancement devices are a guideline-endorsed alternative for moderate OSA, particularly for patients who refuse or fail CPAP.
- Combination approaches such as an appliance plus weight loss or positional therapy often outperform any single measure in moderate cases.
- Success is verified objectively: a follow-up home test on therapy should show AHI back under 5, not just quieter nights.
What This Guide Covers
At 15 to 29 events per hour, breathing is disrupted every two to four minutes all night — moderate disease where treatment clearly helps and both machines and appliances are on the table. The choice usually turns on symptoms, anatomy, and what you will genuinely use. This guide walks you through what matters most, why it happens, and the practical steps with the best support behind them.
First, the foundation: moderate OSA carries measurable cardiovascular and daytime-function risk, so guidelines consistently recommend active treatment rather than watchful waiting.
Next, the details: cPAP remains first-line therapy for moderate disease because it reliably drives the AHI back toward normal when used consistently through the night.
Then, the practical side: custom mandibular advancement devices are a guideline-endorsed alternative for moderate OSA, particularly for patients who refuse or fail CPAP.
Another angle worth knowing: combination approaches such as an appliance plus weight loss or positional therapy often outperform any single measure in moderate cases.
Finally, the big picture: success is verified objectively: a follow-up home test on therapy should show AHI back under 5, not just quieter nights.
Frequently Asked Questions
What exactly is moderate sleep apnea?
At 15 to 29 events per hour, breathing is disrupted every two to four minutes all night — moderate disease where treatment clearly helps and both machines and appliances are on the table. The choice usually turns on symptoms, anatomy, and what you will genuinely use.
How long until I see improvement?
Most of the strategies in this guide start showing effect within one to two weeks of consistent practice. Supplement- and device-based approaches vary more, so track your nights in a simple sleep diary and judge by weekly trends rather than single nights.
When should I see a doctor?
If the problem lasts more than a few weeks, disrupts your daytime functioning, or comes with warning signs such as breathing pauses, gasping during sleep, chest discomfort, or severe daytime sleepiness, it is time to consult a qualified healthcare professional rather than self-treating.
