How to Improve Your AHI Score Overnight
Even when you are fully compliant with your CPAP therapy, you may notice over time that the frequency of your apneas may get worse. This can be frustrating when you have done all that you can to manage your sleep apnea. But there are some simple tips you can follow that can bring down your AHI score overnight.
What is AHI?
AHI, or apnea hypopnea index, is the number of apneas you experience per hour while you sleep. The AHI is used as a guide by sleep doctors to measure the severity of your sleep apnea. Your AHI will ultimately determine the pressure settings on your CPAP machine to minimize the frequency of apnea episodes.
How is AHI Measured?
When being tested for sleep apnea, this score is determined by a polysomnography test (PST). This test measures the number of paused breathing events, as well as the number of shallow breathing events and calculates them to determine your AHI.
During CPAP therapy, your CPAP machine will sense these events and record them to provide insight into whether or not your therapy is working.
What is the Ideal AHI Number?
- An AHI score under 5 is considered normal. That means you experience fewer than five apnea events per hour
- A score of 5-15 indicates mild sleep apnea
- Moderate sleep apnea is determined by an AHI score of 15-30
- AHI scores of 30 apnea events or more per hour indicate severe sleep apnea
How to Reduce Your AHI Score
While minor fluctuations in your AHI are normal, a consistent increase in the number of apnea events per hour is not. Review our list of tips and suggestions for improving your AHI score below. If these don’t help, you may want to speak to your sleep doctor about adjusting your CPAP pressure settings.
Change Your Sleeping Position
Laying in the supine position, (i.e., on your back) is one of the most popular ways to sleep. It is also one of the most common positions in which apneas occur. By changing your sleeping position and simply turning on your side, you may bring down your AHI score without having to change pressure settings or equipment.
Replace Your Mask Cushion and Headgear
Worn out equipment, such as mask cushions and headgear may be to blame for a higher AHI. Headgear straps get stretched out and cushions lose their ability to keep a secure seal over time. This normal wear and tear will contribute to leaks, which reduce pressure and make your CPAP therapy less effective.
Follow your manufacturer’s recommendations for replacing headgear and mask cushions.
Replace Your CPAP Mask
If you continue to see an increase in your AHI score after replacing worn out mask parts, it may be time to try a new mask. On average, it can take individuals 3 or 4 attempts to find the CPAP mask that works best for them. Using your first mask just because it is the only one you know may not be best for your therapy needs. Try experimenting with various other masks to see if they help improve your AHI.
A low AHI score means that your CPAP therapy is effective. Keeping that score low, however, may depend on a number of different factors. Use this list and monitor your sleep data to look for improvements. If you are still struggling, it may be time to contact your doctor about changing your prescribed pressure setting.
