Apnea: The complete absence of airflow through your nose and mouth. Your AHI level will likely fluctuate each night as sleep apnea can be worsened by many factors: Sleeping on your back Having more REM sleep Muscle relaxants Alcohol before bedtime Nasal congestion Since your AHI level can vary depending on the above factors, your doctor will likely average your AHI level over a few months of variations rather than relying on a daily number. If you begin to notice your AHI level increasing there are a few small changes you can focus on before taking the step to switch to a new machine: Sleeping Position: Many individuals with sleep apnea experience a higher AHI level when sleeping on their back as gravity works to pull your airway closed.

This simple adjustment will likely help decrease your AHI level naturally rather than making the decision to change equipment. Individuals who utilize CPAP machines are encouraged to keep track of when mask cushions and headgear are changed so that replacements can be ordered quickly. Headgear stretches out over time resulting in a faulty seal and possible mask leaks.

Advancements are continuing to be made on the design of CPAP masks, so if your current mask has given you issues, there are many others you can try. October 25, at pm Reply. October 25, at am Reply.

September 27, at am Reply. September 26, at pm Reply. Am I the only person who absolutely cannot sleep with the mask? I have had my machine for 3 months. I have both masks, the full face one and the nasal one. After a few hours I give up and pull them off. The longest I have made it is 4 hours twice. Usually average around 2. I know I should wear it, but when I have to get up to go to work in 3 hours and I need to sleep, I just give up.

The pressure seems too much and having hard time. I took both Tylenol PM and melatonin for bot parts of sleep studies since i get insomnia a lot. I have read many articles stating sleep aids can cause inaccurate results.

The pressure makes me panic. Using CPAP is also making me have severe flashbacks and nightmares from being on life support twice this year. I am going back and forth between 3 different mask — Dreamwear gel nasal, Dreamwear full face, and Amara View. I keep taking them off in my sleep so i have to stay awake to meet adherence requirements for insurance.

Anyone have an opinion of which of the masks is best or if anything will help my anxiety? I still worry about results since using sleep aids during testing. Your email address will not be published. Apneas and hypopneas, collectively called events, must last at least 10 seconds to count as events. The AHI is calculated by dividing the number of events by the number of hours of sleep. Gerald on October 7, at pm. Therese on January 11, at pm. Central apneas are indeed calculated in the AHI.

Central apneas are still apneas Reply. George on May 29, at am. Central apneas are indicated by the non-obstructive apneas. Bob on September 14, at pm. Liam O'donohoe on October 5, at pm. Liam Reply.

I have sleep apnea my machine is set on 8 but my air pressure was drying out my nose so i call where i pickrd up machine and she told me to turn it up and i put it on 4 the air pressure is this right Reply. You should never adjust your air pressure you should only be adjusting your humidity if your air pressure is set to 8 you should not change it you should discuss it with your doctor however if you called and they told you to turn it up they were more than likely speaking about the humidity level and that you can adjust on your own my machine comes set to 4 standard or by default I actually turned it up to 5 to get a little more humidity to stop B from drying out this is a good setting for me Reply.

I wake up my sinuses are horrible and puffy eyes Reply. Your CPAP provider should have advice. Mrs Gillian Boehm on June 5, at pm. Some researchers argue that hypopnea and apnea are almost identical events. To qualify as an apnea or hypopnea event, the change in breathing must last at least 10 seconds. The AHI counts both types of breathing disturbance.

The number is used to rate the severity of sleep apnea. It is also used to measure how well treatments such as CPAP machines are working. AHI is the average number of times your airflow is reduced or your breathing stops during one hour of sleeping.

It can be used to rate the severity of sleep apnea and measure how well treatment is working. The first place you may see an AHI is on a sleep study report.

To diagnose sleep apnea, specialists use a sleep study, also called a polysomnogram. These studies usually take place in a sleep disorder center. Sometimes sleep apnea is diagnosed using home sleep apnea testing. These studies track your breathing patterns through the night. They rely on sensors such as these:. The sensors show how many times you stop breathing or breathe shallowly during the night.

They also can detect changes in the oxygen levels in your blood. Some sleep facilities use other measures than the AHI. The respiratory-disturbance index RDI counts apnea and hypopnea events plus less severe breathing interruptions. This oxygen drop may raise your risk of long-term cardiovascular problems such as high blood pressure, heart attack, and heart failure. The oxygen drop could also lead to stroke, dementia, or other neurological problems.

If your sleep study does not contain these more specific measures, it's nothing to worry about. Your breathing can change from one night to the next. For that reason, it probably isn't useful to try to reach a specific daily number. Sleep apnea may be worsened by:. Because your AHI can be affected by these factors, it may be best to calculate your average results over 30 to 90 days.

The optimal goal for you may depend on how severe your condition is. Your goal could also depend on what's causing your breathing problem. 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 events per hour, even lowering it to 10 events an hour may be a big improvement.

More than one event per hour of sleep is considered abnormal. The AHI will be used to help choose the best treatment for you. To interpret your AHI, your health care provider will consider the big picture: your baseline sleep study, anatomy, medications, change in health status, and other factors.

If you have surgery or you use an oral appliance, you may need another test to make sure the treatment has been effective in lowering the AHI. The basic principle is that the machine pushes out air at a steady pressure. It can also send out short bursts of extra pressure. If your airway is partly blocked, the CPAP can measure how much the flow of air slows down.

The measurements of CPAP machines used at home aren't always accurate. If readings stay high without a good explanation, you may need a new sleep study. Modern CPAP machines track the number of breathing events occurring at your current pressure setting.

Each event means that you're waking up briefly or having a short-term drop in blood oxygen level. Using your CPAP will not necessarily prevent the sleep apnea entirely. It depends, in part, on the pressure set by your sleep specialist. Imagine trying to inflate a long, floppy tube by blowing air into it. With too little air, the tube will not open. It will remain collapsed. If the pressure is set too low on your CPAP machine, your upper airway can still collapse.

This could mean ongoing hypopnea or apnea events. Your symptoms could persist if your treatment doesn't go far enough.
