	Dr. Koop - Sleep Apnea- Health Encyclopedia and Reference
		Apnea is defined as a cessation of oronasal airflow of at least 10 seconds in duration.
		In a third type of apnea, mixed apnea, a brief period of central apnea is followed by a longer period of obstructive apnea.
		Polysomnography, a technique used to diagnose obstructive sleep apnea, records the number and duration of apnetic episodes, determines the stage of sleep and oxygen saturation and observes when the patient awakens.

	Apnea - Wikipedia, the free encyclopedia
		Apnea (British spelling - apnoea) (Greek απνοια, from α-, privative, πνεειν, to breathe) is a technical term for suspension of external breathing.
		During apnea there is no movement of the muscles of respiration and the volume of the lungs initially remains unchanged.
		Apnea can be voluntarily achieved (i.e., "holding one's breath"), drug-induced (e.g., opiate toxicity), mechanically induced (e.g., strangulation), or it can occur as a consequence of neurological disease or trauma.

	Sleep apnea - Wikipedia, the free encyclopedia
		Sleep apnea (alternatively sleep apnoea) is a common sleep disorder characterized by brief interruptions of breathing during sleep.
		People with sleep apnea partially awaken as they struggle to breathe, but in the morning they may not be aware of the disturbances in their sleep.
		Sleep apnea also appears to put individuals at risk for stroke and transient ischemic attacks (TIAs, also known as “mini-strokes”), and is associated with coronary heart disease, heart failure, irregular heartbeat, heart attack, and high blood pressure.

	Apnea
		A common type of apnea in children, obstructive apnea is caused by an obstruction of the airway (such as enlarged tonsils and adenoids).
		Mixed apnea is a combination of central and obstructive apnea and is seen particularly in infants or young children who have abnormal control of breathing.
		Apnea of infancy occurs in children who are younger than 1 year old and who were born after a full-term pregnancy.

	The Apnea Board - Sleep Apnea forum, helps, advice
		Central sleep apnea, which is less common, occurs when the brain fails to send the appropriate signals to the breathing muscles to initiate respirations.
		People most likely to have or develop sleep apnea include those who snore loudly and also are overweight, or have high blood pressure, or have some physical abnormality in the nose, throat, or other parts of the upper airway.
		For many sleep apnea patients, their bed partners or family members are the first ones to suspect that something is wrong, usually from their heavy snoring and apparent struggle to breathe.

	Sleep Apnea - symptoms, causes, and treatment of central and obstructive sleep apnea on MedicineNet.com
		Sleep apnea is a disorder characterized by a reduction or cessation (pause of breathing, airflow) during sleep.
		Like apneas, hypopneas are associated with a 4% or greater drop in the saturation of oxygen in the blood and usually occur during sleep.
		Sleep apnea is formally defined as an apnea-hypopnea index of at least 15 episodes/hour in a patient without medical problems that may be related to the sleep apnea.

		Brief periods of apnea are normal during the sleep of newborns.
		Babies suspected of being at risk for more serious apnea, that is to say SIDS, are placed on an apnea monitor, which senses respirations as well as heart rate and gives a loud alarm sound if heart rate or breathing rate limits are violated.

		As a result, people with sleep apnea frequently feel tired during the day because their rest is interrupted by this struggle to breathe.
		Sleep apnea is a condition where the flow of air during breathing decreases or is completely blocked during sleep.
		Sufferers of sleep apnea will get up to urinate after they've been awakened by their snoring or struggle to breath but because they are unaware of the apnea, they assume the awakening was due to the need to urinate.

	Sleep Apnea Information - American Sleep Apnea Association - ASAA
		Obstructive sleep apnea (OSA) is caused by a blockage of the airway, usually when the soft tissue in the rear of the throat collapses and closes during sleep.
		In central sleep apnea, the airway is not blocked but the brain fails to signal the muscles to breathe.
		With each apnea event, the brain briefly arouses people with sleep apnea in order for them to resume breathing, but consequently sleep is extremely fragmented and of poor quality.

	Sleep Apnea (Site not responding. Last check: 2007-11-06)
		Sleep apnea is a disorder in which a person stops breathing during the night, perhaps hundreds of times, usually for periods of 10 seconds or longer.
		Apnea decreases the amount of oxygen in the blood, and eventually this lack of oxygen triggers the lungs to suck in air.
		Evidence suggests, however, that the effect of apneas on coronary artery disease and heart attack is not as significant as it is on heart failure and stroke.

	Sleep Apnoea FAQ / Sleep Apnea FAQ
		Apnea specialists generally agree that there are three different types of sleep apnea: obstructive, central, and mixed.
		Obstructive sleep apnea is characterized by repetitive pauses in breathing during sleep due to the obstruction and/or collapse of the upper airway (throat), usually accompanied by a reduction in blood oxygen saturation, and followed by an awakening to breathe.
		Central Sleep Apnea is defined as a neurological condition causing cessation of all respiratory effort during sleep, usually with decreases in blood oxygen saturation.

	Apnea
		To accurately diagnose apnea, doctors monitor a baby's breathing rate in the NICU and may order a pneumogram, which involves attaching the baby to several monitors and observing him for about 8 to 12 hours.
		The word apnea comes from the Greek word meaning "without wind." Although it's perfectly normal for everyone to experience occasional pauses in their breathing, apnea can be a problem when breathing stops for 20 seconds or longer.
		Most cases of apnea can be treated or managed with surgery, medications, monitoring devices, or sleep centers.

		One measure of sleep apnea is that the person must stop breathing for a period of at least ten seconds or more, five times within an hour.
