What is a good sleep apnea score?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.
How many apnea episodes per hour is 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.

What is a good events per hour with CPAP?An ideal AHI is fewer than five events per hour. That rate is within the normal range. Some sleep specialists aim for one or two events per hour so you're getting better sleep. If the AHI on the sleep study is high, such as 100 events per hour, even lowering it to 10 events an hour may be a big improvement.
Can sleep apnea go away?Does sleep apnea go away? The answer is no, although it is a common question among people with a sleep apnea diagnosis. While there is no cure for this chronic condition, there are treatments and lifestyle changes that can reduce your sleep apnea symptoms.

Fifteen to 30 so-called “events” are rated as moderate sleep apnea, and the presence of more than 30 events per night is classified as severe sleep apnea.
What is a dangerously low oxygen level while sleeping?As a result of not breathing for 30 seconds or more during sleep, your sleep apnea oxygen level would drop to 80% or less. Anything below 90% oxygen level is dangerous to your body and require intervention.
Why am I having so many events on my CPAP machine?When patients return with breakthrough symptoms it is often an issue with the mask. Either the mask is not the proper size, not tightened with a good seal, or there is oral breathing while using a nasal mask.

How does a CPAP machine know when you stop breathing?Automatic CPAP machines vary slightly in that they can detect a collapse of the airway by measuring resistance and react by increasing the pressure as needed during the night to further resolve the sleep apnea. These devices will also test lower pressures and adjust downward if possible.
What is the lowest oxygen level for survival?Human beings must breathe oxygen . . . to survive, and begin to suffer adverse health effects when the oxygen level of their breathing air drops below [19.5 percent oxygen]. Below 19.5 percent oxygen . . . , air is considered oxygen-deficient.
What are the symptoms of low oxygen at night?
What are the symptoms of hypoxemia?

What is considered a low CPAP pressure?The lowest setting on CPAP machines may be 4 to 5 centimeters of water pressure (abbreviated as cm of H2O or CWP). Most people require more pressure than this low setting.
Do I need a CPAP if I have mild sleep apnea?While CPAP therapy is also used to treat mild sleep apnea, it's not always necessary. “It really depends upon what the patient is willing to do,” Khosla says. “CPAP is the most common treatment modality but it certainly isn't the only one.

For moderate to severe sleep apnea, these alternatives are rarely successful.

However, weight loss may help reduce sleep apnea symptoms for some people, but only if you have obstructive sleep apnea.
What is the newest treatment for sleep apnea?For years, the most common treatment for millions of people with sleep apnea involved wearing a continuous positive airway pressure (CPAP) mask. That is, until the U.S. Food and Drug Administration recently approved a new, maskless treatment option -- the Inspire upper airway stimulation device.
