Acid Base Disorders See, Primary disturbance & Secondary response have the same Arrow directions

HIT Type 2 (Immune-mediated, “true HIT”) Mechanism: IgG antibodies form against platelet factor 4 (PF4) + heparin complex → platelet activation, aggregation, consumption.

HIT Type 1 (Non-immune) Mechanism: Direct effect of heparin on platelet activation → mild, transient thrombocytopenia.

HIT type 1 vs 2

What else? 🤔

▪︎ Attacks usually occur at night (rest after exercise, high-carb dinner) ▪︎ Muscle strength returns once potassium normalizes.

Thyrotoxic Periodic Paralysis: ▪︎ Hyperthyroidism → increased Na⁺/K⁺-ATPase activity in muscles → shift of potassium into cells → hypokalemia. ▪︎ Hypokalemia is due to shift, not depletion → aggressive potassium replacement can cause rebound hyperkalemia.
