Pneumonia Leads To Hypoxemia Due To
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
Low oxygen at night: Many causes like sleep apnea, copd, emphysema, heart disease etc. Can cause nocturnal hypoxemia or low level of oxygen at night. It is important medical condition. For its evaluation one may need overnight pulse oximetry to diagnose and if present needs use of home oxygen. Saturation below 87% or less is significant on room air. Consider evaluation by lung doctor if present. ...Read moreSee 1 more doctor answer
Tissues vs. Blood: Hypoxia is low oxygen in the tissues. Hypoxemia is low oxygen in the arterial blood. Hypoxemia caused by low oxygen in air (such as high altitude), low ventilation (slow breathing oversedation), lung disease or blood clots in lung. Low oxygen in arterial blood leads to low oxygen in tissues but hypoxia can also be due to anemia (less oxygen carrying capacity by blood), carbon monoxide poisoning. ...Read more
Related but..: Usually if there is hypoxemia the the body shuts down peripheral perfusion and prefrential flow directed cetrally to vital organs. ...Read more
Hypoxemia...: Refers to low levels of oxygen in the arterial blood which can lead to hypoxia (low levels in the tissues). This information is obtained by lab-ABG. If the patient is having symptoms-respiratory distress, difficulty breathing, increased rate of breathing a nurse should start oxygen and immediately alert the doctor. If no symptoms the nurse should make sure the doctor is aware of the abnormal lab ...Read more
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
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
If someone has 'hypoxemia' and is receiving oxygen, why would they need to be tested for sleep apnea? Wouldn't the oxygen take care of the apnea?
I recently had to have a sleep study done. It cam back that I have obstructive sleep apnea & significant nocturnal hypoxemia. Should I consider cpap or look into things further & see my other options?
Depends: Having sleep apnea is significant, but how severe was your ahi. Moderate to severe osa carries a significant cardiovascular risk and should be treated. The gold standard would be a CPAP and this would be what your insurance generally covers first line. If your osa is more mild to moderate, you could consider alternative treatment options. ...Read moreSee 4 more doctor answers
