What adjustment should be made for a patient on SIMV prior to extubation?

Explanation:
The goal is to support the patient through the weaning process by allowing adequate spontaneous breathing with the least necessary ventilator assistance. In SIMV, mandatory breaths are delivered by the ventilator and spontaneous breaths between them are unassisted, so the patient has to generate most of the work of breathing on their own. Switching to pressure support ventilation provides positive pressure during each spontaneous breath, reducing the work required to take a breath while keeping the same PEEP and FiO2. This helps the patient tolerate an extubation trial and demonstrates readiness for extubation.
