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

Lung (Definition)

Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more

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

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

My blood oxygen saturation is 96% but can there be chances that my blood is not circulation properly to my skin?

My blood oxygen saturation is 96% but can there be chances that my blood is not circulation properly to my skin?

Yes.: At your age chances of lack of circulation is unlikely unless there are preexisting conditions like diabetes or rheumatologic problems like sle, etc. Smoking can also cause it as do some drugs that cause vasoconstriction or closing off of blood vessels. ...Read more

My oxygen saturation fluctuates when standing vs reclining following a whiplash. Heart and lungs are normal. Is phrenic nerve likely causing it?

My oxygen saturation fluctuates when standing vs reclining following a whiplash. Heart and lungs are normal. Is phrenic nerve likely causing it?

Details?: Everyone's oxygen saturation fluctuates regardless of position. When it's being tested, you must remember to keep breathing. This may sound overly simple, but people have a normal tendency hold their breath. An easy way to screen for phrenic n damage is to do a simple chest x-ray. Radiation dose is trivial. The hemidiaphragm will be elevated on the side that has damage, if present. ...Read more

Oxygen saturation drops to 83 to 87 when my new born baby sleeps. Lungs X-Ray and eco screening has shown normal study. What would be the reason.

Oxygen saturation drops to 83 to 87 when my new born baby sleeps. Lungs X-Ray and eco screening has shown normal study. What would be the reason.

Birth History?: Are you testing your baby's oxygen level at home? How many days old is the baby? Was the birth vaginal? Were there any complications? What was the birth weight? How is the baby feeding? How frequent are his stools? Does he show signs of respiratory distress? Does he have a heart murmur? The answer to your question definitely depends on all of the above answers! ...Read more

In a person with sleep apnea, what causes the rises and falls in oxygen saturation of arterial blood during sleep?

In a person with sleep apnea, what causes the rises and falls in oxygen saturation of arterial blood during sleep?

Sleep apnea: Sleep apnea is defined as stopping breathing for 10 seconds. During that time, the body is not getting any oxygen. In addition, there can be instances that last less than 10 seconds, or where a less than adequate effort to breath is attempted. These also reduce the oxygen intake. ...Read more

Why do I get daily attacks of shortness of breath when my peak flow, oxygen saturation, pulse, temperature, blood test and EKG results are all normal?

Why do I get daily attacks of shortness of breath when my peak flow, oxygen saturation, pulse, temperature, blood test and EKG results are all normal?

Breath: Many things can cause you to feel short of breath. One of the most common is a panic attack. Are you prone to them? Other medical conditions such as congestive heart failure with volume overload are frequently seen in elderly patients. Other heart conditions and pulmonary conditions can cause this as well. In a young healthy person such as yourself a panic attack seems more likely. See your Dr ...Read more

Does sepsis usually cause oxygen saturation levels to fall?

Does sepsis usually cause oxygen saturation levels to fall?

It can: Sepsis can cause acute inflammation and swelling in the lungs making it harder to breathe, and causing oxygen levels to drop. Compromised heart and kidney function, as well as fluid resucitation can make matters worse. ...Read more

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

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

I had half of a lung removed due to cancer. Now my blood oxygen level is very low. Will exercise help it?

Confusing: Removing half of one of your lungs should not have severe effects on your blood oxygen level is there are not other problems. See your doctor and ask for a more complete explanation of your functional status and whether or not there are other diseases affecting your blood oxygen level. ...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

What is the likelihood of a blood clot in my lungs if my blood oxygen level is 95%-97%?

What is the likelihood of a blood clot in my lungs if my blood oxygen level is 95%-97%?

Risks: Calculating the risks of a blood clot in your lungs is difficult to do when given only the information of oxygen saturation. A saturation between 95-97% is at or very close to normal, hence it would be impossible to speculate on presence of clot or not. In fact, blood clots to the lung can occur and still result in a normal oxygen saturation between 97-100% clinicians use other factors for risk. ...Read more

Will panic normally cause sudden drop in oxygen saturation levels? With sudden pulse of 144, oximeter went from 95% to 83%. Is that a normal reaction?

Not normal!: I don't know of "normal" reactions to panic. But something was not right to have those vital sign extremes. See a doctor to for an exam and report those stats. A feeling of panic can be a symptom itself, especially if there was no environmental or pre-cursor emotional horror to cause it. If your cardio system is ok, get a referral to a psychotherapist w/ excellent anxiety-panic tx skills. Best wis. ...Read more
