[Blood Transfusion for a Patient on ECMO]

This article describes the case of a middle-aged patient who, following cardiopulmonary resuscitation, was placed on veno-arterial extracorporeal membrane oxygenation (VA-ECMO) with subsequent hemodynamic stabilization. Given a low hemoglobin level and a family request for transfusion, a focused literature review was conducted to assess the appropriateness of blood transfusion in this context. Concurrently, the large language model ChatGPT was evaluated in its Deep Research configuration for its ability to address complex and urgent clinical questions, discussing its advantages and limitations. The case prompted broader consideration of the integration of artificial intelligence into clinical decision-making, the risks of automation bias, and the changing role of physicians in an era where algorithms retrieve information. Nonetheless the clinical responsibility remains on the shoulders of the human clinician.
