Mast cell and basophil degranulation = increased cap permeability, bronchospasm and reduced vascular tone

Question 20

Anaphylaxis presentation?

Answer 20

Airway = angioedema of throat, swelling and stridor
Breathing = SOB, increased RR decreased O2
Circulation = SHOCK -> low bp, high hr, decreased consciousness

Skin mucousal = urticaria and angioedema, flushing
