What Causes Low Oxygen Levels At Night
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 more
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 ...Read more
Many things: Infection, poor air flow into the lungs, poor blood flow to and from the lungs, a heart problem such as a hole within the heart could all cause this. So could a lot of other things, all of which warrant thorough investigation. ...Read more
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?
It can: It can but it shouldn't. Talk to your cardiologist. PFO tend to be small and under low pressure so when you exercise it should not effect things as much. Sometimes there is a pressure reversal and this is not a good sign since it can mean weakening of the heart. ...Read more
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 more
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
Sometimes I can't seem to breathe right. At the ER I was told I had low oxygen levels. What should I do since I don't breathe right?
Depends: Once you have been cleared by your physician that you are safe to exercise. The best thing to do is to exercise with cardiovascular aerobic exercises. This is the best way to build up your stamina and therefore allow you to improve your breathing efficiently. ...Read more
Its hard for me to breathe. I get really bad headaches. Like all the time. And its really hard for me to remember stuff. Possible low oxygen levels?
Possibly: Difficulty breathing and headaches are potentially serious symptoms. I would get into your primary care as soon as you can. Testing oxygen levels is a simple matter of putting your finger in a probe that most offices have these days. That said, presuming you are typically healthy, low oxygen levels would not be the first thing to come to my mind as an explanation for your symptoms. ...Read more
Hard to say: The fetus has low oxygen levels compared to the rest of us for the duration of the pregnancy. Any lab value must be put in context with what is happening. How low, for how long and with what other abnormalities provides a better predictive value. For some premi's, they try to keep it in a lower zone to help prevent eye damage caused by too high oxygen levels while the eyes are developing. ...Read more
Complex question: It may be related to the low oxygen levels you had previously. Depending on the details of being beathless, your question is best answered by seeing a physician face-to-face. Potential causes includes- anemia, heart problems, respiratory issues (eg, . Asthma), infection and many others. Your young age makes heart issues less likely. ...Read more
What is atrial septal defect? Someone here mentioned it when I asked about low oxygen levels, mine was 89 when they checked it the other day,
Atrial septal defect, as the name implies, is a gap in the wall separating the upper chambers of the heart. You may consult this site for more info:

Transient issue: Fetal o2 generally runs low levels while they extract it from mom with the placenta but it is adequate for their needs. During the transition of labor & delivery it continues to remain low ~70 & generally will not come up to regular levels (95+) for several minutes or hours after birth. Scalp abg's @ birth document stress, but are less important than babies vigor & breathing effort @ delivery. ...Read more
I have copd, was put on oxygen due to a bad cold and low oxygen levels. Why am I short of breath while on this oxygen? It's set at 2.
Your shortness of breath can be due to inadequate oxygen getting into your blood. This is a function of gas exchange.
It might be manageable by increasing your oxygen, but you should check with your doctor first. Sometimes increasing the oxygen can actually make you breathe in and out less, resulting in the retention of carbon dioxide - which is bad.
Good luck and feel free to ask more. ...Read more
It can: Asthma can reduce the area of the lung available for co2/oxygen exchange and can do so with variable intensity during an asthma attack. Given a normal o2 % of 94-100, I have seen levels below 50% recorded but patients are usually quite symptomatic below 90%. When an attack is passed and the patient relaxed, the levels return to normal with work of breathing decreased to normal. ...Read more
What would be the cause for hypoxia in 41 yr old, tested oxygen sat., Went down to 78 while sleeping, took sleep study test doesn't seem to be apnea?
Mgt: It really depends on the extent and whether you have any underlying cardiopulmonary disease. ...Read more
Many things.,,: Hypoxia refers to a decreased level of oxygen in the body. Many conditions can result in hypoxia including, but not limited to, lung conditions like acute asthma, copd, pulmonary embolism, etc., cardiac conditions like congestive heart failure, acute mi, valve abnormalities, etc., musculoskeletal conditions like als, diaphragmatic paralysis, etc. Hypoxia can lead to anxiety! ...Read more
Drugs that inhibit cellular respiration? How do cells utilize oxygen and how do you counteract this side effect so patient doesn't die of hypoxia?
It is complex: Your questions are only relevant if you tell us why you are asking about such questions? Please tell us which drug/s you are taking or wanting to understand? . We can not deal with theoretical considerations such as you have posed. Life's physiology is quite complex. I had to study for 10+ years before I could understand questions like this! ...Read more
Hemoglobin: Hemoglobin has four ligands to carry o2, I believe usually 2 used. You give o2, has dissolubility, and membrane transport to enter the cells to the hemoglobin, bind and in tissues where there is acid and low o2 tension and other factors are released to those tissues for energy processing. You give more o2 and the o2 in the plasma increases but not in the saturation of the hemoglobin due to above. ...Read more
I have sleep apnea and a hypoxia index of 17. Is 17 bad or good? I am going on cpap and oxygen. Looking for an answer. Thanks!
Moderately bad: Apnea-hypopnea index of 17 means you obstruct (stop breathing) or partially obstruct an average of 17 times per hour (normal is <5). More important, however, is the degree of oxygen deprivation caused by the disruption. I have many patients who have ahi > 90. If your blood o2 levels are low, your regimen is great. If not low, you can use dental device, likely with good success. ...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
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
