Weaning from mechanical ventilation

This document provides information about weaning patients from mechanical ventilation. It discusses the weaning process, criteria for determining readiness for weaning, procedures for gradual withdrawal of ventilator support, signs of successful or failed weaning, and causes of weaning failure. Weaning involves transitioning the work of breathing from the ventilator back to the patient. Readiness is determined based on clinical, ventilatory, oxygenation, and pulmonary criteria. Weaning methods include spontaneous breathing trials, pressure support ventilation, and synchronized intermittent mandatory ventilation. Close monitoring is needed to identify signs of weaning failure.
