Which set of signs would indicate performing an escharotomy?

• A. SpO2 below 95% with labored breathing and circulatory compromise
• B. SpO2 below 92% with no respiratory distress
• C. SpO2 above 99% with stable vitals
• D. SpO2 below 90% with no symptoms

Answer: (A)

Escharotomy is performed to relieve a constrictive burn eschar on the chest that limits chest expansion and venous return, which can rapidly impair both breathing and circulation after a circumferential full-thickness burn. When the patient is hypoxic (SpO2 dropping below normal) and shows labored breathing along with signs of circulatory compromise, the chest wall obstruction from the eschar is an active threat to life, and an escharotomy is indicated to restore ventilation and improve perfusion. The combination of reduced oxygen saturation with breathing difficulty and circulatory instability points to chest wall restriction as the cause, making this the scenario where the procedure is appropriate. If SpO2 were low but there was no respiratory distress, or if oxygen saturation was normal with stable vitals, or if there was hypoxia but no symptoms suggesting chest restriction, escharotomy would not be the indicated action.
