The actual value of SaO2, or arterial oxygen saturation, typically ranges from 95% to 100% in healthy individuals. It measures the percentage of hemoglobin molecules in the blood that are saturated with oxygen. Values below 90% may indicate hypoxemia and could require medical attention. However, specific values can vary based on individual health conditions and environmental factors.
90%
SaO2 stands for arterial oxygen saturation, which represents the percentage of hemoglobin in the arterial blood that is saturated with oxygen. It is an important parameter in assessing the oxygen-carrying capacity of the blood and is commonly measured using a pulse oximeter.
Then the measured value is larger than the actual value.
%error = (Actual value- Measured value) / actual value *100
To estimate the partial pressure of oxygen in arterial blood (PaO2) when the oxygen saturation (SaO2) is 53%, you can use the oxygen-hemoglobin dissociation curve. At an SaO2 of 53%, the corresponding PaO2 is typically around 30-40 mmHg, although this can vary depending on factors such as pH, temperature, and the presence of other conditions. It's important to consult specific clinical guidelines or tools for precise calculations in a medical setting.
The difference between the Actual Value & Earned Value is the Project Cost Variance
Depending on whether you subtract actual value from expected value or other way around, a positive or negative percent error, will tell you on which side of the expected value that your actual value is. For example, suppose your expected value is 24, and your actual value is 24.3 then if you do the following calculation to figure percent error:[percent error] = (actual value - expected value)/(actual value) - 1 --> then convert to percent.So you have (24.3 - 24)/24 -1 = .0125 --> 1.25%, which tells me the actual is higher than the expected. If instead, you subtracted the actual from the expected, then you would get a negative 1.25%, but your actual is still greater than the expected. My preference is to subtract the expected from the actual. That way a positive error tells you the actual is greater than expected, and a negative percent error tells you that the actual is less than the expected.
You do not add the percentage error but the actual error.
The closeness to the actual value is called the accuracy. The reproducibility of the measurement is call the precision.

This is termed the accuracy of the measurement.
Accuracy describes how close measurements are to the actual value. It is a measure of how well the results agree with the true value of the quantity being measured.
