What is a normal oxygen saturation level?
Your depth of breathing and rate of breathing is adjusted by your body to keep your arterial blood oxygen saturation level about 95+% (this can be checked with a simple oximeter) and the arterial carbon dioxide at 40 mm Hg (this usually requires an arterial blood sample to check).
Causes for low oxygen saturation level?
It could be any number of things. Pneumonia, Emphysema, COPD, Pleural Effusion. Basically anything that will block the alveoli from absorbing oxygen when inhaling. Your doctor will probably order chest x-rays and lab work to see what could be the cause. They can't do a surgery while sats are low because the risk of complicaiton is too high. Think of it like this: if you can breathe normally, then they will have an even harder time keeping your vitals normal. Low O2 sats can lead to respiratory arrest - meaning stopping breathing, and thats definitely not something you want to happen during surgery.
What blood oxygen saturation is normal?
Now for some reason this question was deleted before because i asked "what O2 sat would someone pass out at" and i honestly asked it in the most medical meaning possible. My grandmother is currently dying of pulmonary anemia and her oxygen level is somewhere between 75 and 85. My question is what happens at different O2 sats. What level is normal, what causes confusion, fainting, coma, and death... I honestly hope this question wont be deleted, because i feel that i have done nothing wrong in posting it, i am just wondering about anatomy.
Blood Oxygen Saturation level - what is the fatal and normal range?
This is about my son. He is on hospice care, and is terminal. He is 1 year old, 9 pounds 8 ounces. This is a good weight for him due to proportion. He has a disease called rhizomelic chondrodysplasia punctata. He almost passed in july and barely beat an rsv infection that weakened him significantly. He is on a nasal cannula @ 1l. His oxygen sat level is now in in the high 80s with the 1l nasal cannula delivery. It drops to low 80s or worse at times when he cries or strains, or even urinates. Before these recent episodes he was in the low 90s with no oxygen. We have also put him on a feeding pump, which works with ng tube, to spread out his feeds and avoid fluid shock to his sytem. We will no hospitalize him. He was on oxygen only supplemental until 4 days ago when he had some respiratory episodes and needed to go back on oxygen permanently. I'm trying to get a realistic picture from someone who is no bias.
My oxygen level is 91% Is that too low?
Medical professionals generally consider an O2 sat of 91% too low - but keep in mind that various factors can affect oxygen saturation and a person's "normal" level. COPD patients frequently have O2 sats around 93-94% that we do not treat because their bodies have become accustomed to that level and raising it too much can be detrimental for them. As a young, healthy person with asthma, 91% is too low and should be evaluated. As Chelsea Meissner said, it's not an "emergency" but it is urgent and should be treated to avoid further complications. Now, if your O2 sat was 91% at the time that you were having surgery, that is nothing to be concerned about. Your vitals were closely monitored during that time by a medical team. It's not uncommon for O2 sats to drop when a patient is under anesthesia/sedation, and that's why we place those patients on supplementaly oxygen.
Toddlers oxygen level 83?
This oxygen saturation levels are a cause for concern, yes. This is not normal. It should be in the high 90's if not 100%. However, it's not a fatal situation, but will tell the doctor's that there is something to look for. If she has lung issues, it could likely have to do with that, that her lungs are not drawing in enough oxygen to her body. Often it is a heart related issue, but again, these things can often be fixed, so don't stress too much. Having the levels that low for a very long time would be a problem, but at this very second, it's not critical, however, I'd call the doctors now unless they gave you a particular number to watch for (ie if it drops below 80%, call us). I remember 80% being an important range when my son was in the NICU with heart issues.
What is the lowest oxygen level before the body shuts down?
This is NOT a TRAVEL question. some people with serious cardiac problems have an oxygen level in the 70s all the time...for example, babies born with heart defects. They can survive like this for a long time if corrective measures cannot be done promptly. Babies often stay in the hospital for months on special medication waiting for a heart transplant and their best oxygen level is in the 70s. adults.... are in a bad way with an o2 level of 72. Usually, that patient would be on oxygen nasally or on a ventilator. Most people will faint with an oxygen saturation level that low. that does not mean they are near death if the period of time their level is low is brief. how near death is depends on the reason for the low oxygen level. You may get additional answers if you place your question in the HEALTH category.
How long can you have a blood oxygen level in the mid-high 70s before signifigant brain damage occurs?
How long can you have blood oxygen levels in the mid-high 70s without significant brain damage?? Lol, my older sister just peered over my shoulder, read your question and walked off yelling "That explains a lot!" (!!!) Yep, I love her too. Due to my congenital heart disease (hlhs and tapvd) and my reconstructed cardio-pulmonary circulation, my sats (blood oxygen levels) are always around 75%. I don't think they've gone any higher than 75% for at least the past year. Having only "half a heart" and having (ahem) a pretty unique, surgically-built circulation, I'd be in *big* trouble (with lung damage) if my oxygen sats were to go above 85%. Talking of low oxygen sats, I've known other heartkids with sats as low as the 50s who hadn't got brain damage on the back of it. I think if a person's blood oxygen levels are consistently low * for any substantial length of time (so that their body has had a chance to try to adjust) they are far more likely to develop multi-organ failure than brain damage. I think brain damage is more associated with a sudden, sharp drop in blood oxygen levels. * (lowest I've heard of was 48%)
How long can a person survive with low oxygen levels?
Short Answer: It depends on the situation, the adaptations of the person, and the mechanism of hypoxia.Long answer:Hypoxia, or low blood oxygen, is probably the fastest and deadliest killer I know, but it does depend on the situation. Whether you’re at sea level or in the Death Zone above 20,000 feet, air contains 21% oxygen. Below 20%, we start to see hypoxia, which, if not corrected, can easily be fatal. Below 15%, we’re seeing serious acute hypoxia, and someone is really risking serious injury or death. Below 10%, survival is measured in minutes to seconds. Usually, these kinds of oxygen levels are seen in confined spaces or industrial applications; something external to the body is causing the amount of oxygen in the air to be low (CO2, CO, pure nitrogen, etc).More frequently, hypoxia is caused by injury/illness, or by altitude. Altitude means that the air is thinner, the molecules spaced more widely, meaning that the body must work harder to find oxygen. Injury or illness affects the body’s ability to process oxygen, through a pretty wide range of mechanisms. In both cases, anything that gets in the way of the oxygen getting into the body, or into the bloodstream, or through the bloodstream, or into the cells, can and will kill. Rapid hypoxia, as with choking or irreversible shock, can kill within seconds to minutes. Hypothermia, or low body temperature, may increase the amount of time that a patient remains viable.However, people can adapt to and survive pretty low oxygen levels. The Sherpa of Nepal and the various ethnic groups in the Andes are the most extreme examples I can think of; basically, these are human beings living their entire lives at extreme altitude. Himalayan climbers, especially those who climb without supplemental oxygen, also come to mind. Given the oxygenation numbers found during the medical testing during the Cauldwell Xtreme Everest Expedition, given the right physiological changes, the right amount of time, and the right person, humans can adapt to survive for hours or even days at blood oxygen levels that would kill someone at sea level. Exactly how this happens, and whether it is true for all humans, is still being studied.
