What are the advantages of OSA therapy?
The targets of OSA therapy are to alleviate indicators and signs, enhance sleep high quality, and normalize apnea-hypopnea index (AHI) and oxygen saturation ranges. The potential advantages of profitable therapy of OSA embody improved scientific efficiency (e.g., lowered daytime sleepiness), lowered well being care service use and associated prices, and probably lowered cardiovascular complication charges and mortality.
