Snoring Obstructive Sleep Apnea and Treatment Animation
Snoring and sleep apnea.In normal breathing, air enters the nostrils and goes through the throat and the tracheato the lungs. In people who snore this airway is partiallyobstructed by excess tissue of the throat, such as large tonsils, large soft palate ortongue. Another common cause of obstruction is the dropping of the tongue into the throatdue to over relaxation of tongue muscles during sleep. Air currents competing throughnarrow spaces in the throat cause the soft palate essentially a piece of soft tissuehanging in the throat to vibrate. This vibration is the source of the noise we hear when someoneis snoring.
Sleep apnea happens when the airway is completelyobstructed, no air can go through and the person stops breathing. This cessation ofbreathing triggers the brain to respond by waking up the person just enough to take abreath. This repeats itself again and again during the course of the night and may resultin sleep deprivation. Snoring and mild sleep apnea may be treatedwith a mandibular advancement device. This device is designed to move the lower jaw andthe tongue slightly forward and thus making the space in the back of the throat larger.
Obstructive Sleep Apnea
MUSIC Obstructive sleep apnea. 30 million Americans may sufferfrom obstructive sleep apnea, or OSA. It is more common thanadult diabetes and asthma, affecting 24% of men and 9% of women between the agesof 30 to 60 years of age. OSA is even more commonin overweight people and
persons older than60 years of age. It is a major risk factor for the development ofcardiovascular disease. Studies show that 80%of difficult to control hypertension, 50% ofcongestive heart failure, and 60% of strokes are relatedto undiagnosed OSA. Apnea means without breath, ifyou have obstructed sleep apnea you literally stop breathingwhile you're asleep.
The apnea can last fora few seconds to a minute or more, as many as 100 oftimes during the night. Forms of sleep apnea includeobstructive, central and mixed with obstructivebeing the most common type. OSA prevents you from reachingdeep stages of sleep, which the body needs to rest andreplenish itself. Causes ofObstructive Sleep Apnea. Even though the exact causeof OSA remains unclear,
the sleep disorderfollows a pattern. During the day muscles keepthe airway passages wide open. When a person withOSA falls asleep, these muscles relax to a pointwhere the airway collapses and causes a breathing pause. These breathing pauses occurbecause of a blockage in the upper airway. Usually when the soft tissuein the upper airway or
rear of the throat collapses. When the airway closes,breathing stops and the sleeper wakes upto open the airway. The sleeper thenreturns to sleep and the breathing pauseoccurs again. This pattern is repeated untilyou wake up for the day. Symptoms ofObstructive Sleep Apnea. OSA is most commonlyseen in overweight
people with loud snoring,breathing pauses, usually noticed by the bedpartner, daytime sleepiness, thrashing around in bed,morning headaches, a dry mouth in the morning, andgasping for breath at night. Loud snoring and daytime sleepiness are the mostcommon of these complaints. Other symptoms of OSAinclude memory problems, as well as difficultyconcentrating and thinking.
