The oxygen dissociation curve (not affected by Hb concentration)

The L rule

Shifts to L → Lower oxygen delivery, caused by

• Low [H+] (alkali)
• Low pCO2
• Low 2,3-DPG
• Low temperature

Another mnemonic is 'CADET, face Right!' for CO2, Acid, 2,3-DPG, Exercise and Temperature

Metabolic acidosis secondary to high lactate levels may be subdivided into two types:

• lactic acidosis type A: shock, hypoxia, burns
• lactic acidosis type B: metformin

Anorexia features

• most things low
• G's and C's raised: growth hormone, glucose, salivary glands, cortisol, cholesterol,carotinaemia

Causes of Hypercholesterolaemia rather than hypertriglyceridaemia:

• nephrotic syndrome,
