This case report describes an 83-year-old male with multiple comorbidities who was intubated after his negative inspiratory force dropped below -30 cm H₂O and treated with plasmapheresis, leading to partial improvement. Despite not meeting standard extubation criteria, he was successfully extubated, maintained stable respiratory function, and was safely discharged. This case highlights the challenges of extubation in GBS patients, where advanced age, decreased physiological reserve, and comorbidities increase the risks of prolonged intubation and complications. This case also highlights the need for individualized extubation strategies in GBS, particularly in elderly patients who may not meet standard criteria.
