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? WebbWeaning from mechanical ventilation is the process of decreasing the amount of ventilatory support, with the patient gradually assuming a greater proportion of the overall work of ventilation. As mentioned in Chapter 15, weaning and extubation at the earliest possible time are among the a priori goals of mechanical respiratory support.
