Tachycardia
🟡 Tachycardia is an expected early sign of hypovolemic shock because the body tries to compensate for reduced circulating volume by increasing the heart rate.
🟡 Major burns cause large fluid shifts out of the vascular space, which lowers effective perfusion.
🟡 The heart responds by beating faster to maintain cardiac output.
🟡 This compensatory response is common in early shock.
🟡 Therefore, tachycardia is an expected finding.
Restlessness
🟡 Restlessness is an early indicator of decreased cerebral perfusion and hypoxia in shock states.
🟡 Clients may become anxious, restless, or confused before more obvious signs of decompensation appear.
🟡 This finding should never be dismissed because it may signal worsening tissue perfusion.
🟡 In burn-related hypovolemia, reduced oxygen delivery to the brain contributes to this symptom.
🟡 For these reasons, restlessness is an expected manifestation.
Cool, clammy skin
🟡 Cool, clammy skin occurs because the body shunts blood away from the skin to preserve perfusion to vital organs.
🟡 Vasoconstriction is a classic compensatory response in hypovolemic shock.
🟡 Even though burns affect the skin, systemic shock still produces peripheral vasoconstriction in less-injured areas.
🟡 This finding supports worsening circulatory compromise.
🟡 Therefore, cool, clammy skin is anticipated.
Tachypnea
🟡 Tachypnea is common in shock because the body attempts to improve oxygen delivery and compensate for metabolic acidosis.
🟡 As tissue perfusion decreases, anaerobic metabolism increases, leading to lactic acid buildup.
🟡 Faster breathing helps compensate for this metabolic imbalance.
🟡 It also reflects physiologic stress and oxygen demand.
🟡 For these reasons, tachypnea is expected in hypovolemic shock.
Decreased urine output
🟡 Decreased urine output is an important sign of reduced renal perfusion in shock.
🟡 As circulating volume falls, the kidneys receive less blood flow and urine production decreases.
🟡 Oliguria is one of the clearest indicators that organ perfusion is being compromised.
🟡 In burn shock, strict urine output monitoring is essential.
🟡 Therefore, decreased urine output is an expected manifestation.
Hypertension
🟡 Hypertension is not expected in hypovolemic shock.
🟡 The blood pressure typically trends downward as circulating volume is lost.
Hyperglycemia
🟡 Hyperglycemia may occur with stress responses, but it is not one of the hallmark bedside manifestations used to identify hypovolemic shock initially.
🟡 The more classic findings are changes in perfusion, pulse, breathing, skin, and urine output.
