what is the formula for calculating the percentage saturation of haemoglobin with oxygen. Oxygen content is calculated by estimating the oxygen carrying capacity of the patients blood as haemoglobin bound oxygen. The pulse oximeter measures the haemoglobin providing a mean saturation percentage SpO2.

Oxygenated hemoglobin divided by msimum saturation and then times by 100. Percentage saturation of haemoglobin with oxygen oxygenated haemoglobin maximum saturation x 100 When fully saturated each molecule of haemoglobin is bound to four molecules of oxygen. Give the formula for calculating the percentage saturation of haemoglobin with oxygen.
Pulse oximeters are generally accurate in measuring oxygen saturation between 70 and 100 percent.
Solubility of gases increases by an amount equal to the surface saturation concentration for about every 10 m increase in depth. For a compound to be saturated there is one more hydrogen in a molecule when nitrogen is present. Hb Hct MCHC Assuming a normal MCHC of 32-36 gdl Ive chosen 35 for convenience then the first patients Hb is about 7 and the second patients Hb is about 14. Use this information and information from the graph to calculate the volume of oxygen released to the muscle from 1 dm3 of blood.
