Causes For Low Oxygen Levels
Hypoxia, is a condition in which the body as a whole or a region of the body is deprived of adequate oxygen supply. It is classified into 4 groups: - hypoxemic - oxygen is low - anemic - decreased ability for hemoglobin to carry oxygen. - ischemic - decreased blood flow. - histotoxic - oxygen is reaching the cells, but the cells are unable to use ...Read more
Other diseases: If you ask me what causes low o2 in a perfectly normal and healthy elderly it makes a difference. There is an alveolar to arterial ratio that changes with age, and o2 is lower in elderly by this notion alone but no to point of hypoxia. There is such thing as senile emphysema by age alone, with the changes like that of the skin. See the compressibility of finger as the machine could restrict pulse. ...Read moreSee 1 more doctor answer
Can Pfo cause low oxygen levels while exercise. My oxygen levels drops down to about 88 while i am walking, then at rest it goes up to 98?
No: No, certainly not directly. That is, stress can cause a lot of problems, but it would not in of itself cause you to have a low oxygen level. For example, stress could lower your immunity. You could then be more susceptible to getting a lung infection, and then the lung infection could cause a low oxygen level. ...Read more
Atelectasis: Sometimes, there can be parts of the lung not fully inflated called atelectasis. This could cause low oxygen levels and can be reversed by taking deep breaths. This type of lung exercise can be done using something called an incentive spirometer, and walking around. Hope this helps! ...Read more
What could cause low oxygen levels after a carotid artery surgery and then hematoma removal surgery? Dry esophagus from ventilator?
Yes: Think about americans who live in denver, sherpas that live in tibet, & the maya in south america. These are populations of people who have become accustomed in one way or another to a lower atmospheric oxygen level, and in the mayans a lower blood oxygen level. Another sea-level example would be a person with emphysema who may run a blood oxygen level of 88% and still be walking around home depot. ...Read more
Oxygen: The normal o2 in the blood is calculated as that which should be calculated by knowing the lung, the age, water vapor pressure, etc. Very complicated. For our purposes, we set at that oxygen which will give us a saturation of hemoglobin at least 90% in the arteries. If it is lower than that it is low. ...Read more
Yes: However, chronically low oxygen levels can cause changes in the heart. Figuring out why is important. Possible causes include chronic lung diseases, neuromuscular weakness or chest wall deformity, pulmonary vascular diseases, and of course sleep disordered breathing such as sleep apnea. Weight also plays a big role. ...Read moreSee 1 more doctor answer
Lung disease: Is the commonest reason for a low level of oxygen in the blood. It can also happen in heart disease if the heart is failing and fluid builds up in otherwise-healthy lungs, or if there is a hole in the heart, causing blood to bypass the right heart circulation into the lungs and skip picking up oxygen there. These are examples of some common causes. Smoking, high altitude=examples of lung reasons. ...Read more
Bronchospasm...: Wheezing typically is a result of bronchospasm which has many different causes. Possible etiologies include asthma, copd, pneumonia, acute or chronic bronchitis, etc. All of these can lead to low oxygen levels so you need to see your doctor for a precise diagnosis and treatment. Your oxygen level qualifies you for supplemental oxygen therapy and your doctor can prescribe this for you as well. ...Read more
If low oxygen levels are causing seizures would the best way to treat them be finding out why oxygen is dropping?
If that is the case?: When you experience a seizure, your oxygen level might dip and your carbon dioxide will also change. Many metabolic changes accompany seizures. I suspect that oxygenation due to seizure activity, not the reverse. You do not list your current anti-seizure meds, but i presume you are taking some medication. Altering your medicines may successfully control the seizures. ...Read more
