Is Sleep Apnea And Hypoxemia The Same Thing
Sleep apnea has two causes. It may be 'central' or 'obstructive'. Central apnea occurs as a disorder in the way the brain controls breathing. Obstructive sleep apnea is much more common and involves an anatomical blockage of the airway. Usually, the tongue blocks the airway, preventing the passage of air between the a sleep study is needed to diagnose particular ...Read more
Obstruction vs CO2: Central apnea is caused by the brain's inability to respond to elevated co2 (carbon dioxide) levels in the blood. Obstructive sleep apnea is caused by the collapse of the airway when the muscles of the throat, tongue, and possibly the palate when they are flaccid/paralyzed during the deeper stages of sleep. Osa responds well to CPAP and dental devices. Central may not. ...Read moreSee 1 more doctor answer
Apnea: Obstrutive due to dynamic narrowing of upper airway (nose/throat/wind pipe) by a large tongue, jaw deformities, obesity. Pt usually snores. Central apnea there is no obstruction, usually no snoring . Conditions like heart-kidney failure, stroke, sedatives cause brainstem to decrease respiratory drive when sleeping. Need to treat the conditions. ...Read moreSee 4 more doctor answers
Unrelated: Obstructive sleep apnea is more of a physical problem. There is an obstruction in the airway during sleep (excess weight, collapsed tongue, enlarged tonsils, small pharynx, etc. Central sleep apnea is where the brain does not control breathing properly during sleep. Neither is related to PTSD. PTSD and sleep apnea can co-exist, but one does not cause the other or increase risk of the other. ...Read more
Several: Being over weight is probably the biggest risk factor. A loss of muscle tone in neck muscles as we get older. Heredity undoubtedly plays a role. Having a large tongue. Other contributing factors are an underdeveloped lower jaw, a narrow upper jaw and a high palate. These all tend to block the airway and lead to obstructive sleep apnea. In central sleep apnea the brain doesn't say to breath. ...Read moreSee 1 more doctor answer
Reduced breathing: Sleep apnea is when you stop breathing while you are asleep. This results in waking up at night many times over and/or having reduced blood oxygen levels. The primary symptom is sleepiness called "excessive daytime somnolence." you can take a simple questionairre here: http://www.Umm.Edu/sleep/epworth_sleep.Htm if you believe that you have sleep apnea, see a sleep specialist right away. ...Read moreSee 1 more doctor answer
2 different condtion: sleep apnea is when there is a cessation of airflow with sleep and breathing. The most common type of sleep apnea is obstructive sleep apnea when the upper airway gets blocked. Nocturnal hypoxia is a general term for low oxygen with sleep. Sleep apnea can cause nocturnal hypoxia, though many other conditions can cause nocturnal hypoxia without sleep apnea such as copd or heart disease. ...Read more
Depends: There are a lot of reasons for sleep apnea starting from birth allergies, to ill formed nasal passages, high vaulted palates, ill formed dental arches, nasal patency , enlarged tongue , high bmi to name a few and these are for obstructive apnea of corse it could be central and that is a different ball game. ...Read moreSee 1 more doctor answer
Different problems: Sleep apnea is a breathing-related sleep disorder involving brief periods that a person stops breathing while sleeping. This triggers an alarm system in the brain to wake the person up so he/she will start breathing again. Nocturnal panic attacks are discrete periods involving extreme anxiety associated with physiological changes in heart rate, breathing, sweating, etc. That occur at night. ...Read moreSee 1 more doctor answer
In a person with sleep apnea, what causes the rises and falls in oxygen saturation of arterial blood during sleep?
Sleep apnea: Sleep apnea is defined as stopping breathing for 10 seconds. During that time, the body is not getting any oxygen. In addition , there can be instances that last less than 10 seconds, or where a less than adequate effort to breath is attempted. These also reduce the oxygen intake. ...Read moreSee 2 more doctor answers
Overlap: Nocturnal hypoxia is a drop in oxygen in the blood when sleeping. It's associated with sleep apnea, but also with hypoxic chronic bronchitis pulmonary hypertension and emphysema. Sleep apnea can be due to airway obstruction or of central origin. It causes reduced oxygen, often dangerously, and arousal from sleep, leading to daytime fatigue. ...Read moreSee 1 more doctor answer
What is the definition of sleep depravation? Ex: how many days (hrs) of no sleep defines someone as sleep deprived.
Various: The gold standard for treatment of obstructive sleep apnea is nasal cpap, or continuous positive airway pressure. However, this is sometimes poorly tolerated. Some case of sleep apnea are treated with oral appliances to advance the mandible and open the airway. Some patients are good candidates for surgical correction to move the jaws forward to open the airway. Treatment depends on many factors. ...Read moreSee 3 more doctor answers

This is the cessation of breathing for 10 seconds or more. Most apnea is obstructive being caused by collapse or obstruction of the airway leading to lack of air flow. However, it can be a central process, where the respiratory center of the brain fails to signal the respiratory respiratory system to initiate a breath. Lastly, some apnea is mixed central ...Read more
This really depends on the patient. For normal patient who does not smoke very low oxygen level could be defined as an oxygen saturation less than 88% or a partial pressure of oxygen measured in blood gas less than 60 mmhg. For an active smoker these numbers may be different. For someone with underlying lung disease again these ...Read more
