Obstructive Sleep Apnea (OSA) is a common sleep disorder, and the CPAP machine (Continuous Positive Airway Pressure device) is the gold-standard treatment. With many brands and models available, how do you choose the best CPAP machine for you? This article offers the latest buying guide, including recommendations, price comparisons, usage tips, and cautionary advice, to help improve your sleep quality and regain a healthier life.
1. What a CPAP Machine Does & Who It’s For
1. How a CPAP Machine Works
- Delivers constant positive air pressure to keep the airway open
- Prevents airway collapse that causes breathing pauses during sleep
- Enhances blood oxygen saturation and reduces nighttime awakenings
2. Who Needs a CPAP Machine?
✅ Diagnosed moderate to severe OSA (AHI ≥ 15/hr)
✅ Loud snoring with daytime sleepiness
✅ Hypertension or heart disease coexisting with sleep apnea
✅ Post-operative recovery needing breathing support
⚠️ Note: A formal polysomnography (PSG) sleep study is required before use—do not purchase on your own!
