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

Oxygen (Definition)

Oxygen is a gas that the cells in your body need to work properly. The air we breathe normally has 21% oxygen. A maximum of 100% oxygen can be given. Babies with heart or lung problems may need ...Read more

What is o2 saturation level?

What is o2 saturation level?

Oxygen in the blood: Oxygen saturation is the percentage of the hemoglobin ( the part of the red blood cell that carries oxygen through the blood)that is carrying oxygen. ...Read more

Can atrial flutter cause o2 saturation to be lower?

Can atrial flutter cause  o2 saturation to be lower?

Maybe: If the atrial flutter impairs the filling of the ventricles it can lead to decreased cardiac output which in turn can lead to pulmonary edema which, when severe enough, can impair gas exchange and decrease o2 saturations. ...Read more

82 yr old o2 saturation level was more than 95% on ventilater but after removeing ventilater her o2 saturation drop up to 30% will she recover?

82 yr old o2 saturation level was more than 95% on ventilater but after removeing ventilater her o2 saturation drop up to 30% will she recover?

Depends: The cause of desaturation is the main way to tell the prognosis. She is on a ventilator so she is sick. But what is the cause? It also depends on the length of time she has been ill, the degree of settings of the ventilator. It is difficult to make a prediction without these informations. ...Read more

Would low O2 saturation levels at night below 90 for 2 to 3 hours with Cpap result from breast cancer radiation ? Normal lung function , chest X-ray

Would low O2 saturation levels at night below 90 for 2 to 3 hours with Cpap result from breast  cancer radiation ?  Normal lung function , chest X-ray

Probably not: Radiation damage to the lung can be detected functionally on pulmonary function tests. If your pulmonary function tests are completely normal, it would be unlikely that radiation lung damage was the cause of the fall in 02 saturation. ...Read more

Does an av canal cause decreased o2 saturation in the blood?

Does an av canal cause decreased o2 saturation in the blood?

Yes, it can.: Yes, atrioventricular canal (av canal) defects can result in decresed oxygen saturation if there is a residual shunt (mixing of blue and pink blood) which can happen in presence of elevated pressures in the lung (pulmonary hypertension). Decresed oxygen saturation can also result from lung disease and other conditions. ...Read more

O2 saturation 0.93 mol, pc02 5.6 kpa, po2 8.8 kpa, std bicarb 24.0 mmol/l are these normal results? If no what can cause this?

O2 saturation 0.93 mol, pc02 5.6 kpa, po2 8.8 kpa, std bicarb 24.0 mmol/l are these normal results? If no what can cause this?

It depends: We use lab test to help characterize the underlying condition, and to try to determine what to do next. When they are presented in the absence of the clinical situation, we can't make any conclusions one way or another. ...Read more
