Sleep Apnea is part of the spectrum of what is called “Sleep Disordered Breathing” or “SDB.” The condition Sleep Apnea is commonly broken into three main categories. The three main categories of Sleep Apnea are as follows:

Obstructive Sleep Apnea (OSA)

Central Sleep Apnea (CSA)

Mixed Sleep Apnea (MSA)

The three main categories, or types, of Sleep Apnea will be discussed in more detail below. Sleep Apnea is commonly and effectively treated with CPAP therapy (Continuous Positive Airway Pressure). Keep in mind that this is not a comprehensive treatment on the subject of Sleep Apnea. For more information please reference the citations at the end of the article or speak with your doctor.

Obstructive Sleep Apnea (OSA)With Obstructive Sleep Apnea, the soft tissue of the upper airway collapses during the night and slows air intake, eventually eliminating air intake altogether. When oxygen intake is reduced or eliminated and blood oxygen levels fall significantly, the brain sends an emergency signal to wake up and resume a normal breathing pattern. This process can happen as many as a few hundred times a night for some people with severe OSA. The use of a CPAP machine either drastically reduces these “apneic” events or eliminates them altogether. This results in the restoration of a normal breathing pattern and the CPAP user is able to achieve deep, REM(3) sleep, allowing the body to do routine maintenance and restore many healthful functions in the body.Central Sleep Apnea (CSA)Central Sleep Apnea is similar to OSA in its final effect on the sufferer, however, the mechanism of oxygen reduction is different. The principal mechanism of oxygen reduction in CSA is due to a failure of the brain to send a proper breathing “signal” to the muscles that control the breathing process. This type of Sleep Apnea is more rare than OSA and according to the Mayo Clinic accounts “for less than 5 percent of sleep apneas.”(4) Even though CSA is different in function than OSA, the outcome for the sufferer is the same–reduced oxygen intake through out the night, failure to reach deep sleep cycles and general fatigue throughout the day. Fortunately, in most cases, CSA can be treated with the same equipment that is used for those that suffer with OSA. Most CPAP, BiPAP and APAP machines have sophisticated circuitry which allows for the detection of different types of apneas, allowing the machine to adjust to the needs of the user throughout the night.Mixed Sleep Apnea (or Complex Apnea)According to the National Institutes of Health, Mixed Sleep Apnea is defined as a combination of both Obstructive Sleep Apnea and Central Sleep Apnea. The technical explanation for Mixed Sleep Apnea according to the NIH is as follows: “intervals of ten seconds or longer during which there was a complete cessation of airflow accompanied by an absence of respiratory effort in the early part of the apneic episode and a resumption of respiratory effort in the latter part.” Basically, this means that a CSA-related apneic event occurs, followed by an OSA-related apneic event. Interestingly, according to the study by the NIH, the sequence of events is always from CSA to OSA and never in reverse. In other words, the brain fails to send a signal to breath, resulting in an apneic event, followed by a collapse of the airway that further impedes oxygen flow. This makes sense, as it would not seem vary likely that an airway collapse related to an OSA-type event would cause the brain to misfire a breathing signal, however, a misfire by the brain would include the muscles involved in breathing and may lead to a loss of good muscle tone in the upper airway.

Obstructive Sleep Apnea is an illness that many people fail to recognize until after the symptoms have caused grief to the family and employers. In fact, the spouse is often the first one to realize that there may be a physical reason for the odd behaviors and symptoms of someone suffering from sleep apnea (OSA).

Someone suffering from this sleep disorder will often snore very loudly. The snoring may be so loud, in fact, that his or her partner gets little sleep. Someone with OSA will also appear to stop breathing for a second or two during sleep, which looks like they’re temporarily holding their breath. The subsequent lack of oxygen causes them to be startled awake, but often they are completely unaware that they wake up many times during the night. Since the individual usually drops back to sleep almost immediately, and then begins snoring again, partners often believes they are the only ones missing sleep. This can be a severe strain on the relationship, especially if the person with OSA refuses to seek treatment.

It may look as though an individual with this sleep disorder is getting lots of sleep, so it seems strange to others if the individual has difficulty staying awake during the daytime, even dropping off to sleep at inappropriate times. They may have difficulty concentrating, and appear depressed. Because they really aren’t getting quality sleep during the night, they may also have a reduced interest in sex, and other personality changes can also occur. Some of these symptoms are similar to common mental health disorders, and others are seen by friends and coworkers as symptoms of laziness or sloth. This judgement can add to the individual’s stress, and can make relationship problems even worse.

If someone you know who suffers from these symptoms, it would be wise to encourage them to see their doctor. The snoring and obstructed breathing during sleep usually have a physical cause, which may vary from one individual to another. There may be an obstruction in the upper airway due to excess tissue caused by obesity, or the tonsils or tongue may be too large. In addition, the airway muscles are usually relaxed or collapse during sleep.

Some of the causes of sleep apnea are also associated with other life-threatening conditions. A proper diagnosis is important, because if the individual goes without treatment he or she will have an increased risk of heart attack, stroke, irregular heartbeat, and other forms of heart disease. In addition to the physical risks of this sleep disorder, relationships with families, friends and employers may continue to suffer. Productivity at work will go down because the individual is so abnormally sleepy, and it can become dangerous to work with heavy equipment or drive an automobile.

There are a number of ways that obstructive sleep apnea can be treated, including the use of a C-PAP (continous positive airway pressure) machine. This machine has a nose mask that is worn during sleep. The C-PAP machine keeps air blowing into the nose, which will keep the airway open. If obesity is a causitive factor in sleep apnea, as it often is, the patient will be advised to slim down. Weight loss is almost always accompanied by a complete cessation of sleep apnea symptoms, and for this reason some obese OSA patients are opting for gastric bypass surgery.

Because sleep apnea may be caused by a variety of factors, and because the symptoms could also be caused by sleep disorders other then OSA, a diagnosis by a qualified professional is needed before treatment can begin. Your doctor will usually prescribe a sleep test, which is done by a specialized clinic. This test is usually covered by medical insurance, but it is always a good idea to call your insurance carrier to see if they require you to visit a clinic that is contracted with them. The results of the sleep test will tell your doctor if any form or respiratory equipment is required, or if surgery is indicated. Experimental treatments, such as the Radio Frequency Procedure developed by Stanford University, will probably not be covered by your insurance.

Do you snore, or do you sleep with someone who snores so loudly that you can’t get any sleep? It’s time to see a doctor to find out if sleep apnea is to blame.

Adjustable Beds May Improve Sleep Apnea Symptoms

Getting a diagnosis of obstructive sleep apnea scares a lot of people. They wonder how they will ever sleep with peace of mind, but getting good sleep isn’t as hard as you think. There are many things you can do to improve your sleep.

One tip doctors give patients is to raise the head of the bed to help prevent the tongue from falling back and blocking the airway. An adjustable bed helps sleep apnea sufferers get quality sleep by readjusting the airway naturally.

In obstructive sleep apnea, the airway collapses and/or gets blocked by the tongue. Lying flat promotes the collapse in sleep apnea sufferers. The tissues gets pulled to the lowest point by gravity. This narrows the airway or completely cuts off airflow through the passages. The apnea patient’s body then must arouse itself to reestablish breathing. Raising the head of the bed allows gravity to work in a positive manner and will help keep the tongue and airway in an open position.

Overweight people tend to have more issues sleeping due to painful pressure points and airway compromise. The tissues in and around the neck gain weight just like the rest of the body. This weight gain makes the airway smaller and harder to breathe through. An adjustable bed can relieve areas of tenderness and increase the airway size by adjusting to a position that is comfortable for the user. The beds are sturdy and most are rated to adjust a weight of up to 650 lbs. Some studies claim that using adjustable beds for sleep apnea have shown positive results.

Adjustable beds are perfect for people who need to keep the head higher than the feet. These beds are automatic, no more hand cranking, and they can also be bought as split units. These units allow both sides of the bed to be adjusted differently. This keeps both people in a relationship happy. They can also be purchased with memory foam mattresses which will increase the comfort level of the user(s).

Most of these beds now take up less room with a wall hugging frame. They are a lighter weight so average people can move the bed if needed. Most of them come in sizes ranging from twin to king. Prices have come down tremendously and are now affordable. Insurance companies sometimes cover the cost of an adjustable bed when sleep apnea is a diagnosis and a doctors prescribes it.

An adjustable bed can be a lifesaver for sleep apnea sufferers. They come in many sizes and are available with several options from massage and heat to split frame and memory foam mattresses. These beds raise the head and increase airway passages by utilizing gravity in a positive manner.

Some insurance companies may cover the cost of adjustable beds for sleep apnea sufferers if a doctor clearly states the need. Check with your doctor to see if he or she believes an adjustable bed will help, and ask your insurance company if they cover the cost partially or in full.
