. Core Physiology & Definition Definition: Shock is inadequate tissue perfusion to meet metabolic demands and oxygenation needs1. Hypotension is not required for diagnosis; shock exists with normal, high, or low SBP1.Pediatric Focus: Infants have fixed stroke volume and depend on elevated heart rate to maintain CO3.Stroke Volume: Preload (volume), Contractility (pump force), and Afterload (resistance)34.2. Severity & Compensatory Continuum Compensated Shock: Body mechanisms (tachycardia, elevated SVR, venoconstriction) maintain normal SBP despite hypoperfusion56. Key signs: tachycardia, delayed refill, cool skin, oliguria67.Hypotensive Shock: Compensatory mechanisms fail, causing low SBP and imminent arrest7. Hypotension is a late finding...
