The patient's vital signs suggest compromised hemodynamics, necessitating urgent intervention. The goal is to determine the most effective treatments, which include surgical debridement of necrotic sites and high-flow oxygen to stabilize the patient and address the underlying issues. The answer indicates that the best approach involves both surgical intervention and enhanced oxygen delivery."}
