Which of the following criteria for weaning a patient with Guillain-Barré syndrome from mechanical ventilation have shown to be predictive of weaning success?
1) VC greater than 18 ml/kg
2) Transdiaphragmatic pressures greater than 31 cm H₂O
3) PImax greater than 30 cm H₂O
4) Cardiac output above 2.0 L/min

Question

Quizplus · Accepted Answer

1) A vital capacity (VC) greater than 18 ml/kg indicates sufficient respiratory muscle strength for weaning. 2) Transdiaphragmatic pressures greater than 31 cm H2O suggest adequate diaphragm function. 3) A maximal inspiratory pressure (PImax) greater than 30 cm H2O is indicative of good respiratory muscle strength, essential for successful weaning. Cardiac output, while important for overall patient status, is not directly predictive of weaning success from mechanical ventilation in the context of Guillain-Barré syndrome.
