What Is The Blood Oxygen Saturation Levels Are Supposed To Be After Tetralogy Of Fallot
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
Typically no: Typically no unless the stroke affects breathing. ...Read more
My blood oxygen saturation is 96% but can there be chances that my blood is not circulation properly to my skin?
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?
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
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
No: No, there is no correlation.Get a more detailed answer ›
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
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
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
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
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
Normal: I believe you are talking about newborns with a pectus who is on the ventilator. If this is the case, the saturation should be normal 99%, unless there is something else affecting the oxygenation level. ...Read more
Home sleep study said moderate sleep apnea w/severe oxygen saturation <70 & in-clinic study said no sleep apnea & perfect oxygen levels. Which right?
My reaction: Advise you to sit down with your doctor and go over both studies in full detail, as one of these is clearly WRONG. Although I would favor a clinic outcome due to presence of skilled personnel, I cannot clarify the outcomes from this perspective. Good luck with this. ...Read more
Lungs are clear (ct scan) heart is okay (echocardiogram, ekg) then why oxygen saturation levels are low?
Please: Have evaluation by a pulmonologist.Get a more detailed answer ›
No: 92% is not severely abnormal but is abnormal for someone who is otherwise healthy and as young as you. Note that pulse oximetry is not perfect technology, however, and may not always be accurate. ...Read more
