When people lose weight, their hemoglobin and hematocrit (the ratio of red blood cell volume to total blood volume) both go up. But does it work the other way around?

Using Hgb and Hct as a Guide to Hydration Status Both the hemoglobin and the hematocrit are based on whole blood and are therefore dependent on plasma volume. If a patient is severely dehydrated, the hemoglobin and hematocrit will appear higher than if the patient were normovolemic; if the patient is fluid overloaded, they will be lower than their actual level.

In this StickEnote I go over the connection of Hemoglobin and Hematocrit. Hgb – Hemoglobin = 10 – 14 Females 12-16 Males • Hemoglobin carries oxygen so it’s about perfusion • Low is Acute and it is…
