Obstructive Sleep Apnea
So what is obstructive sleep apnea (OSA)? Apnea means a total cessation of breathing and this happens only when one is sleeping. So a person with sleep apnea can stop breathing from 10 to 50 to even over 100 times every hour with each episode lasting anywhere from 10 to 30 seconds. Using strict criteria, it is estimated that about 4% of men and 2% of women have this condition, but using looser criteria, it can be up to 25% in men and up to 10% in women (via sleepeducation.com).
The scary statistic is that OSA is not diagnosed in about 80-90% of people who have it (via sleepfoundation.org); so instead, they are being treated for the end result which can be diabetes, depression, high blood pressure, etc. It is also significant that OSA happens in about 35% of chronic snorers. It is also important to note that you don’t need to snore to have sleep apnea, as well.
Obstructive Sleep Apnea Symptoms
- Snoring
- Daytime sleepiness/falling asleep at the wheel
- Chronic dependence on caffeine or energy drinks
- Depression/irritability
- Poor concentration/memory/focus problems
- Morning headaches
- Poor job performance/attention deficit disorder
- Obesity
Diagnosing OSA
So how is OSA diagnosed? To diagnose OSA you should undergo a formal sleep study at the comfortable Woodinville Sleep Improvement Center. The overnight test is easy and preliminary results for the test are available as soon as the following day. We analyze different parameters like breathing, heart rate, brain waves, limb movements etc. while you sleep. This way we can determine what is fragmenting your sleep.
Speech and OSA Diagnosis
If you’re human, and you can talk, then you’re susceptible to breathing problems at night, even if you don’t suffer from any apneas. The reason is that complex speech and language development unprotected our upper airways, and everyone’s tongue can fall back and obstruct your breathing at night, especially when you’re in deep sleep, due to muscle relaxation.
Associated Medical Conditions
- 50% greater incidence of high blood pressure (HTN)
- 1½ times more likely to have heart disease
- Diagnosed depression- 18 times more likely have OSA
- Increased risk of Type II Diabetes
Central and Complex Sleep Apnea
Besides insomnia, obstructive sleep apnea (OSA) is the most common sleep issue for men and women. However a significant number of people with obstructive sleep apnea (OSA) may also have central sleep apnea or complex sleep apnea (CSA) which is a combination of the two. CSA is thought to be a condition that’s associated with a number of different neurologic problems, as well as heart or kidney failure.
During the night, people with CSA stop breathing when signals in the brain that tells the body to breathe do not work properly. Exhaling during sleep could also become problematic and may result in dangerous Co2 retention. To make matters worse for those who have CSA, no effort is even made to inhale. In contrast, with OSA, an effort is made to breathe in and out, but because of collapse in the upper airways, air can’t get into the lungs.
Treatment
Unfortunately, treating some cases of CSA is more of a challenge than treating OSA. The most effective method of treating challenging CSA conditions is to use a variation of CPAP as a respirator. This breathing machine is called an assisted servo-ventilator (ASV). When the ASV senses that you’re not breathing, it literally breathes for you, rather than applying constant positive pressure for obstructive events.
Falling asleep at the wheel
It is estimated that about 800,000 car accidents occur every year due to sleep apnea and of these, there are about 1,400 fatalities. In addition, it is estimated that of all the commercial truck drivers in America, about 28% of them have OSA(via sleepjournal.com).
