In order to determine what kind of sleeping disorders a patient may have, our specialists may schedule a sleep study at one of our sleep centers.

The most common type of sleep apnea is obstructive sleep apnea, caused by relaxation of soft tissue in the back of the throat that blocks the passage of air.

Note: the U.S. census treats Hispanic/Latino as an ethnic category. This table excludes Latinos from the racial categories and assigns them to a separate category. Hispanics/Latinos may be of any race.

The NHLBI is the nation's leader in the prevention and treatment of heart, lung, blood and sleep disorders.

As you sleep, the airstream from the CPAP machine pushes against any blockages, opening your airways so your lungs receive plenty of oxygen.

CPAP machines only push out air at one rate, which is calibrated by the doctor to the average rate needed by the sleeper. Since some people have trouble tolerating this continuous level of air pressure, other options are available.

Since an APAP machine can detect when a person has stopped or slowed their breathing, it can also provide an estimate of how many abnormal breathing events a person experiences per night and per hour. The machine can also detect when the mask is leaking air.

As sleep study doctor surrounding communities grew or were constructed, they came to require access to waterlines, which was under the sole control of the municipal water system. Rhodes told these communities that if they wanted water, they would have to submit to assimilation into Columbus.[76] Neighborhoods

APAP (automatic positive airflow pressure) machine. This kind checks your breathing throughout the night. It automatically adjusts the air pressure to compensate for changes in your sleep position or medications that may have changed your breathing.

CPAP stands for continuous positive airway pressure. Air is applied through a mask that will fit over your face. The air splints the airway open so that you will be able to breathe continuously.

Obstructive sleep apnea is often treated with nonsurgical intervention first. Some of those less-invasive treatments include: Lifestyle changes – Avoiding alcohol or smoking, as well as losing weight, can help manage your sleep apnea.

The mask conducts pressurized air through your nose, or through your nose and mouth, to your throat. The added pressure in your throat then keeps it from collapsing while you sleep, so you can breathe normally.

CPAP is considered the most effective OSA treatment, but it must be used nightly. CPAP therapy is less effective at treating central sleep apnea. 

Mouthpieces and other devices – A continuous positive airway pressure (CPAP) machine is a common treatment recommended for sleep apnea.
