What is nocturnal hypoxemia?

What is nocturnal hypoxemia?

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 more

Very Low Oxygen Level (Definition)

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

What's the difference between sleep apnea and nocturnal hypoxemia?

What's the difference between sleep apnea and nocturnal hypoxemia?

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 more

What are the differences between sleep apnea and nocturnal hypoxemia?

What are the differences between sleep apnea and nocturnal hypoxemia?

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

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?

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 more

Explain hypoxia vs hypoxemia?

Explain hypoxia vs hypoxemia?

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

Can you tell me about nursing intervention for patient with hypoxemia?

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

Is there any cure for hypoxemia in chronic bronchitis?

What does severe hypoxemia affect the heart's electrical system?

Can laryngectomee patients suffer from hypoxemia during the winter season?

Can laryngectomee patients suffer from hypoxemia during the winter season?

Not necessarily: It is dependent on the ability of air to get, which should not be a problem and the ability of the lung to transfer oxygen into the blood. The problem is that if you look at people who undergo laryngectomy, many were smokers who also had bad lungs. ...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?

Perhaps.: The hypoxemia may be related to sleep apnea. No, if you have sleep apnea, either the airway is blocked (obstructive) or you don't breath (central). In either case, sleep studies are indicated. ...Read more

I have just been diagnosed with hypoxemia with a sleep study. A sleep study 2 years ago showed significant RLS with legs moving 76 times a hour. Can it be related to the RLS? I also move my arms 12 times an hour. I am on CLonazepam 0.5 mg and Mirapex 0.75

I have just been diagnosed with hypoxemia with a sleep study. A sleep study 2 years ago showed significant RLS with legs moving 76 times a hour. Can it be related to the RLS? I also move my arms 12 times an hour. I am on CLonazepam 0.5 mg and Mirapex 0.75

What else did study: Show? RLS is a cause of poor sleep and daytime somnolence, but it should not be associated with hypoxia. Did the study show any evidence of either central or obstructive sleep apnea? While your clonazepam is a very low dose, if you have underlying lung disease or other causes of hypoxia, it may be contributing to it. You need to talk to the physicians who ordered and interpreted your study. ...Read more

Why do I only have seizires at night?

Why do I only have seizires at night?

Several reasons: It is hard to come up with a definitive answer without more information. It is possible that your seizures are sensitive to light so if you spend time on the computer or tv at night, the flickering lights may precipitate your seizures. There are also some types of seizures that tend to occur more or even only at night (and are called nocturnal seizures). Some of these are inherited conditions. ...Read more

Why might someone keep coughing at night?

Depends: Depends on the causes: pneumonia, sinusitis, bronchitis, allergy... You can cough all day or more at night. At night when you lie down, your airway tends to be more collapsed and narrow. You also don't clear your throat of drainage or mucus as much as during the day. For those reasons, your airway is more irritated at night making you cough more. ...Read more
