apnea /ap·nea/ (ap´ne-ah) cessation of breathing.apne´ic
central sleep apnea sleep apnea from failure of stimulation by medullary respiratory centers. obstructive sleep apnea sleep apnea from collapse or obstruction of the airway during sleep, such as in the obese. sleep apnea transient attacks of apnea during sleep, resulting in acidosis and pulmonary arteriolar vasoconstriction and hypertension.
Apnea The temporary absence of breathing. Sleep apnea consists of repeated episodes of temporary suspension of breathing during sleep.
apnea [apnē′ə, ap′nē·ə] Etymology: Gk, a + pnein, not to breathe an absence of spontaneous respiration. Types of apnea include cardiac apnea, deglutition apnea, periodic apnea of the newborn, primary apnea, reflex apnea, secondary apnea, and sleep apnea. Also spelled apnoea. -apneic, adj. apnea [ap´ne-ah] cessation of breathing, especially during sleep. The most common type is adult sleep apnea. Central apnea in which there is failure of the central nervous system drive to respiration sometimes occurs in infants younger than 40 weeks after the date of conception. adult sleep apnea frequent and prolonged episodes in which breathing stops during sleep. Diagnosis is confirmed by monitoring the subject during sleep for periods of apnea and lowered blood oxygen levels. Sleep apnea is divided into three categories: (1) obstructive, resulting from obstruction of the upper airways; (2) central, caused by some pathology in the brain's respiratory control center; and (3) mixed, a combination of the two (see above). Treatment. Obstructive and mixed types are amenable to therapy. Since many sleep apnea patients are overweight, weight loss improves the symptoms. Central sleep apnea is the most difficult to control. Medications to stimulate breathing have not proven beneficial. Mechanical ventilation or administration of oxygen during the night may help some patients. The most common treatment for obstructive sleep apnea is nasal continuous positive airway pressure, which the patient uses during sleep; the positive pressure exerted prevents the airway from obstructing. Another method that may be tried is a dental appliance to move the jaw forward during sleep. In the most refractory cases, such as when an anatomical airway obstruction can be demonstrated, surgery to remove it may be performed after consultation with a surgeon experienced in evaluating and treating such obstructions. Another treatment that is occasionally used is insertion of a special type of tracheostomy tube that can be plugged during the day for normal use of the upper airway and opened at night to bypass upper airway obstruction central apnea (central sleep apnea) see adult sleep apnea. deglutition apnea a temporary arrest of the activity of the respiratory nerve center during an act of swallowing. initial apnea a condition in which a newborn fails to establish sustained respiration within two minutes of delivery. late apnea cessation of respiration in a newborn for more than 45 seconds after spontaneous breathing has been established and sustained. mixed apnea see adult sleep apnea. obstructive apnea (obstructive sleep apnea) see adult sleep apnea. primary apnea cessation of breathing resulting when a fetus or newborn infant is deprived of oxygen; exposure to oxygen and stimulation usually restore respiration. prolonged infantile apnea sudden infant death syndrome. secondary apnea a period of time following primary apnea during which continued asphyxia of the fetus or newborn, with a fall in blood pressure and heart rate, necessitates artificial ventilation for resuscitation and reestablishment of ventilation. sleep apnea transient periods when breathing stops during sleep; see adult sleep apnea.
apnea (apˑ·nē· n cessation of breathing; arrested respiration.
apnea (apnē´ n a temporary cessation of respiratory movements.
apnea 1. temporary cessation of breathing. 2. asphyxia. sleep apnea
transient attacks of failure of autonomic control of respiration, becoming more pronounced during sleep and resulting in acidosis and pulmonary arteriolar vasoconstriction and hypertension. apnea Sleep disorders A cessation of airflow of ≥ 10 seconds Grading Mild-obstructive apnea-hypopnea index of ≤ 20; moderate 20–40; severe ≥ 40.

Just been there for the test for both and they said ‘yes’. It looks like I have them. Just need to know what to expect. Thanks a bunch in advance. A. untreated sleep apnea can: Increase the risk for high blood pressure, heart attack, stroke, obesity, and diabetes Increase the risk for or worsen heart failure Make irregular heartbeats more likely Increase the chance of having work-related or driving accidents so here's a list of things you can do: http://www.sleepapnea.org/resources/pubs/treatment.html Q. my ears do not hear well especially when it's cold. i hear my breath and heart beat. what's my prolem? Denis when i breathe it feels like the breath goes through the ear when the weather is cold or when i do some excercise like jogging A. what you hear is the pulse of the arteries in your ear. the cold thing might be because of pressure differences between inner ear and outer environment. this can pressure the ear drum from the inside, leaving you hearing only your thoughts...

It used to be thought that apnoeic snoring had absolutely no acute effects on brain function but this is plainly not true," said New South Global Professor Caroline Rae, the lead author of the study. Her son Oliver suffered from the start from deafness and respiratory problems, including apnoeic attacks, which halted breathing up to 60 times a day. |
