What is a good ahi number?

An AHI less than 5 is considered normal, and some patients with severe sleep apnea may be told by their doctor that they can accept even higher numbers so long as they’re feeling more rested each morning, experiencing fewer symptoms and their AHI is progressively decreasing.

What is a good ahi number with CPAP?

What does AHI mean?

The apnea-hypopnea index (AHI) is a scale that tells whether you have a sleep disorder called apnea and, if so, how serious it is. Sleep apnea is when you stop breathing for 10 seconds or more while you’re asleep.

Why is my ahi so high?

There are three reasons that your AHI may rise. First is mask leak. If air is escaping your CPAP mask, you’re not getting all the air pressure needed to keep your airway open and as a result AHI rises. Second is consumption of alcohol, narcotics and drugs which increases obstruction and as a result AHI.

How do I lower my ahi with CPAP?

How to Reduce Your AHI Score

  1. Change Your Sleeping Position. Laying in the supine position, (i.e., on your back) is one of the most popular ways to sleep.
  2. Replace Your Mask Cushion and Headgear. Worn out equipment, such as mask cushions and headgear may be to blame for a higher AHI.
  3. Replace Your CPAP Mask.

How accurate is CPAP ahi?

Auto-CPAP AHI of eight events per hour yielded the optimal sensitivity (0.94, 95% CI 0.73 to 0.99) and specificity (0.90, 95% CI 0.82 to 0.95) with a positive LR of 9.6 (95% CI 5.23 to 20.31) and a negative LR of 0.065 (95% CI 0.004 to 0.279) to identify patients with a PSG AHI of > or = 10 events per hour.

Does sleep apnea shorten life span?
