What is a good apnea-hypopnea index?
From the rating chart here, we see that an index less that 5 is considered normal. For an Apnea-Hypopnea Index from 5 to 15 denotes mild sleep apnea. Fifteen to 30 is moderate, while a greater than 30 is considered severe.
What AHI is considered severe sleep apnea?
Severe obstructive sleep apnea means that your AHI is greater than 30 (more than 30 episodes per hour) Moderate obstructive sleep apnea means that your AHI is between 15 and 30. Mild obstructive sleep apnea means that your AHI is between 5 and 15.
How many hypopneas in an hour is normal?
None or minimal: Less than 5 events per hour. Mild: Between 5 and 15 events per hour. Moderate: Between 15 and 30 events per hour. Severe: More than 30 events per hour.
What does a high AHI mean?
If your AHI increases over time, or remains elevated, this could also be an indicator of other sleep disorders, such as central sleep apnea or complex sleep apnea. These may require alternative treatment, such as a BiPAP or auto-cpap (APAP) to ensure that your therapy can maintain the proper oxygen levels.
How many apnea events per night is normal?
Normal: Fewer than 5 breathing events per hour of sleep. Mild sleep apnea: 5 to 14.9 breathing events per hour of sleep. Moderate sleep apnea: 15 to 29.9 breathing events per hour of sleep.
How does a CPAP machine know when you are asleep?
How does my CPAP machine know when I fall asleep? Your AirSense 10 will know you’re asleep no more than three minutes after. That’s because the moment you turn on your machine, AutoRamp is looking for three things: 30 breaths of stable breathing (roughly 3 minutes)

Do I have to Use CPAP Forever? It’s important to understand that using your CPAP machine won’t cure your sleep apnea. But CPAP therapy will help you achieve a restful sleep despite having this condition. As long as you have sleep apnea, you will continue to need to use CPAP therapy.
Should I use my CPAP if I have a cold?
It’s never easy to sleep when you have an upper respiratory tract infection, a cold or flu, but for people on CPAP therapy, it is more difficult to tolerate treatment at this time. Stopping using your CPAP when you have a cold is not advised as it can make other cold symptoms such as a sore throat a lot worse.
How many apnea events per hour are normal?
That’s because it’s considered normal for everyone to have up to four apneas an hour. It’s also common if your AHIs vary from night to night. For some CPAP users, even higher AHIs are acceptable, depending on the severity of your sleep apnea.
How often should you change the tubing on a CPAP machine?
Replace CPAP tubing, whether it is heated or standard, every three months. Tubing gets dirty over time, with condensation increasing the risk of contaminants that could enter your lungs. Small holes that form as the plastic of the tubing breaks down reduce the treatment’s efficacy.
