Sleep disorders are highly prevailing in majority of regions globally and is affecting the population health severely. Troublesome ill effects of the disorder are important cause for increase in rate of adoption for sleep apnea diagnostic systems. Sleep apnea is a chronic disorder that can be bifurcated in two different types- obstructive sleep apnea (OSA) and central sleep apnea. Among the two, obstructive sleep apnea is a common form of sleep apnea and around 3% – 4% of the population is affected.
Obesity and rapidly rising aging population play a crucial role in the growth of the global sleep apnea diagnostic system market
Obstructive sleep apnea (OSA) also called obstructive sleep apnea syndrome. It occurs when there are repeated episodes of complete or partial blockage of the upper airway during sleep. During a sleep apnea episode, the diaphragm and chest muscles work harder to open the obstructed airway and pull air into the lungs. Breathing usually resumes with a loud gasp, snort, or body jerk. These episodes can interfere with sound sleep. They can also reduce the flow of oxygen to vital organs and cause irregular heart rhythms.
Symptoms of OSA
Signs and symptoms of obstructive sleep apnea include:
· Excessive daytime sleepiness
· Loud snoring
· Observed episodes of stopped breathing during sleep
· Abrupt awakenings accompanied by gasping or choking
· Awakening with a dry mouth or sore throat
· Morning headache
· Difficulty concentrating during the day
· Experiencing mood changes, such as depression or irritability
· High blood pressure
· Nighttime sweating
Many people may not think that snoring as a sign of something potentially serious, and not everyone who snores has obstructive sleep apnea.
Be sure to talk to your doctor if you are experiencing loud snoring, especially snoring that's punctuated by periods of silence. With obstructive sleep apnea, snoring usually is loudest when you sleep on your back, and it quiets when you turn on your side.
Obstructive sleep apnea occurs when the muscles in the back of your throat relax too much to allow normal breathing. These muscles support structures including the back of the roof of your mouth (soft palate), the triangular piece of tissue hanging from the soft palate (uvula), the tonsils and the tongue.
When the muscles relax, your airway passage narrows or closes This may lower the level of oxygen in your blood and cause a buildup of carbon dioxide.
Your brain senses this impaired breathing and altering you from sleep so that you can reopen your airway. This awakening is usually so brief that you don't remember it.
You can awaken with shortness of breath that corrects itself quickly, within one or two deep breaths. You may make a snorting, choking or gasping sound.
This pattern can repeat itself five to 30 times or more each hour, all night long. These disruptions impair your ability to reach the desired deep, restful phases of sleep, and you'll probably feel sleepy during your waking hours.
People with obstructive sleep apnea may not be aware that their sleep was interrupted. In fact, many people with this type of sleep apnea think they slept well all night.
