Webb6 feb. 2024 · IDENTIFYING PATIENTS SUITABLE FOR WEANING Many studies show that a spontaneous breathing trial (SBT) is a good method of identifying patients ready to be weaned from mechanical ventilation. This is commonly done using a pressure support ventilation (PSV) mode or a T-piece trial. WebbInstead, gradual support reduction (true weaning) strategies using either synchronized intermittent mandatory ventilation (SIMV) or pressure support ventilation (PSV) was the approach. As noted above, the potential exists that this gradual support reduction approach might have actually prolonged the ventilator discontinuation process in some patients.

Webb9 nov. 2024 · The original intent of SIMV was to rest the respiratory muscles during the mandatory breaths and to work the muscles during the spontaneous breaths. Weaning is achieved by decreasing the mandatory breath rate, requiring more spontaneous breathing effort to maintain the minute ventilation. What is the most common ventilator mode?
