Please help docs! Is oxygen saturation the same things as oxygen uptake?

Please help docs! Is oxygen saturation the same things as oxygen uptake?

Not quite: Oxygen saturation reflects the proportion of red blood cell pigment - hemoglobin that is loaded ("saturated") with oxygen. It is unitless and shown as %. Oxygen uptake is the quantity of oxygen absobed/ consumed per unit time, usually in milliliters per min. ...Read more

Hypoxia (Definition)

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

What common medical conditions are associated with low oxygen saturation levels?

Lung & Heart Disease: Hypoxia (low oxygen saturations) are usually caused by lung disease (chronic obstructive pulmonary disease, asbestosis, pulmonary fibrosis, etc). Many heart conditions (especially congenital defects in the new born) may result in low oxygen saturation levels. Beware of false lows with pulse oximetry readingson cold hands, peripheral vascular disease or really callussed finger tips. ...Read more

How much does a low oxygen saturation level affect judgment?

Oxygen: A low oxygen saturation definitely affects judgment. Your brain is one of the organs that is heavily dependent on proper oxygenation. If you decrease the oxygen saturation, judgment may be impaired. ...Read more

Does bronchiolitis cause low oxygen saturation?

Does bronchiolitis cause low oxygen saturation?

It happends: Bronchiolitis causes a build up of secretions in the tiny airways and blocks transfer of oxygen into the tissues. It can and does cause a drop in blood oxygen in many cases. ...Read more

What damage does low oxygen saturation have on a childs brain?

What damage does low oxygen saturation have on a childs brain?

Depends on variables: Low saturations are a variable issue. In the womb, the baby draws oxygen from the mothers blood and during all of pregnancy, their oxygen saturation is below what we expect after their first hour of age. That said, when it is too low for the period, it forces the metabolism into a weaker method of supplying energy, starving brain cells of energy and could result in cell injury or permanent damage. ...Read more

Does the low oxygen saturation experienced on a commercial flight have a negative effect on a baby's developing brain?

Does the low oxygen saturation experienced on a commercial flight have a negative effect on a baby's developing brain?

Heaven forbid!: Can you imagine the class action lawsuit on that? And what about anyone else with chronic lung disease? No worries. The cabins are pressurized and oxygenated. If that is disrupted, that masks pop down. Air travel is much safer than the highways. ...Read more

What happens if I set a hyperbaric chamber to low oxygen saturation and used it would I still get altitude sickness?

Weird: Why do weird stuff? Altitude sickness is often prevented with diamox (acetazolamide). Hyperbaric chamber management should be entirely left to doctors. Do not selfexperiment with that stuff. ...Read more

Does asthma cause hypoxia? What is the oxygen saturation in people who have asthma?

Does asthma cause hypoxia? What is the oxygen saturation in people who have asthma?

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 causes low oxygen levels after surgery?

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 are the causes of low oxygen sat rates after surgery?

What are the causes of low oxygen sat rates after surgery?

Interpret right: It depends on the timing. Worst could be pulmonary embolus form immobility several hours after. But right after surgery, usually the or is cold and causes closing off of skin arterioles (response to cold temp) and since the monitor is dependent on pulses could read wrong. The best time to ask is when it is happening as the health officer can correlate with timing and symptoms. ...Read more

What helps the body maintain a healthy oxygen saturation levels?

O2 goes into lung: Traverse the interstitial to the blood vessel wall to the blood cells goes to tissues and be delivered. Normal saturation therefore depends on the oxygen source, healthy alveoli with enough surface area, thin and healthy interstitial and blood vessel wall and normal and adequate blood cells and healthy consumption of o2. That is the balance. ...Read more

Why when I get difficulties breathing or sob, yet my oxygen saturation is 99-98%. How and what could that be. What is the symptom of low oxg saturat

Dyspnea: Shortness of breath is largely unrelated to oxygen levels, except when very low. Work of breathing causes dyspnea (shortness of breath) and can occur with normal oxygen levels. When oxygen levels become very low dyspnea can occur. ...Read more

Is an oxygen saturation of 69% when sleeping dangerously low?

Yes: 69% saturation is quite low. Does the patient stop breathing at night (sleep apnea)? Do they have copd? Asthma or other lung disease?
These questions need to be answered. The primary care physician should be consulted and a sleep study ordered. ...Read more

How do I get my oxygen saturation level up?

Dr. Tony Su Dr. Su
2 doctors agreed:

Several factors: Several factors determine oxygen saturation. These include the amount of oxygen you breathe, the ability of the lungs to extract oxygen, the amount of red cells to carry oxygen, the ability of the heart and blood vessels to deliver oxygen to tissues, and efficiency of organ to use oxygen, any problems affecting these can cause low saruration. Treating a disease, exercise, supplemental o2 may help. ...Read more

Are oxygen saturation levels lower in the elderly?

Not necessarily: As we age, it may get a little harder for the oxygen to get into the blood through your lungs. But, as long as you have healthy lungs, the oxygen saturation levels can be normal well into one's 80s or 90s. ...Read more

Why can't I breath but my oxygen saturation level is good?

Why can't I breath but my oxygen saturation level is good?

Shortness of breath: ...Is caused by many abnormalities in the body, not simply low o2 levels. Some patients can have significant shortness of breath from copd, pneumonia, asthma and other illnesses without a low o2 level. If you continue to have trouble, you should see a doctor for evaluation to figure out why this is happening. ...Read more

How much can a low venous oxygen saturation affect judgement?

So, there is no general rule about that... ...Read more

Is 98 percent oxygen saturation level for a smoker who has been smoking for19 years good?

Smoking and Oxygen: Yes. But the test is deceptive. It does not mean you do not have lung damage. It does not measure how much carbon dioxide you have or how many of your red blood cells are no longer available to carry oxygen. It just tells me that you are still young enough that you have some ability to maintain good oxygen levels despite the nineteen years of trying to damage your lungs. ...Read more

For blood oxygen saturation level - what is the fatal and normal range?

Oxygen sat curve: If you look at the p50 or oxygen saturation curve, anything above 90% is ok for the hemoglobin to unload as it gets into the tissues and supply them. As the curve goes down to 75% about pao2 of 45, this nears the saturation in the veins where unloading of oxygen to the tissues including heart muscles becomes difficult and there will be eventual death as it gets lower than that. ...Read more

What is oxygen saturation (spo2) while sleeping that is dangerously low?

What is oxygen saturation (spo2) while sleeping that is dangerously low?

It all depends: Without knowing a detailed medical history to determine if "low" oxygen may be a chronic, well compensated issue, it is impossible to answer. Typically normal oxygen staurations are within 94-97% while sleeping. Patients with sleep breathing disorders, like sleep apnea may experience dips in this saturation. However, it is standard to try and keep saturation above 89%. Talk to your doctor. ...Read more
