The oxygenhemoglobin dissociation curve also called the oxyhemoglobin dissociation curve or oxygen dissociation curve ODC is a curve that plots the proportion of hemoglobin in its saturated oxygen-laden form on the vertical axis against the prevailing oxygen tension on the horizontal axis. The shunt equation can now be used to determine how much mixed venous blood one would need to add to the capillary blood to create the systemic arterial oxygen content which is 117mlL. The oxygen content calculator uses the haemoglobin levels in gdL the percentage of oxygen saturation and O 2 arterial pressure in mmHg to determine the arteria oxygen content.
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.
You could assume certain things though to make an estimate of the bloods oxygen content. Where percent saturation. Hb 3 O2 75 saturation. P50 of myoglobin 28 torr.
