Shock is clinically best assessed by -: (A) Urine output, (B) CVP, (C) BP, (D) Hydration
Answer is A. • Shock: Inadequate delivery of oxygen and nutrients due to poor tissue perfusion to maintain normal tissue and cellular function
• Mean arterial pressure <60 mm Hg in previously normotensive patients
• Systemic vascular resistance rises leading to decreased cutaneous blood flow and autoregulation is critical in sustaining cerebral and coronary blood flow.
