Study Notes
Building Schemata with Major Haemorrhage
- Oxygen Loss and Respiration: Loss of oxygen (O2) can lead to anaerobic respiration, or respiratory alkalosis, not aerobic respiration or ATP production.
- Altered PH in Major Haemorrhage: Changes in blood pH during major haemorrhage can impair treatment responses, affect enzyme function, and cause cardiac arrhythmias.
- Normothermia Impairment: The body's ability to maintain normal temperature is impaired in major haemorrhage, due to peripheral vasoconstriction, preventing O2-rich blood and clotting factors from reaching the peripheries.
- Fluid Replacement: Fluid replacement during major haemorrhage, while waiting for blood products, should involve restricted crystalloid fluid replacement aiming for a lower blood pressure target, not baseline.
- Treatment Goal: Treatment for major haemorrhage aims to eliminate the lethal triad, comprising coagulopathy, metabolic acidosis, and hypothermia, not other variations of the triad.
- Cryoprecipitate Function: Cryoprecipitate is used to increase fibrinogen levels and manage clotting, not produced from platelets or as an oxygen carrier.
- Massive Transfusion and Calcium: Calcium is administered during massive transfusion to activate clotting, not potassium for its cardiac effects.
