C. Correct response: Two large randomized trials of weaning conducted in the 1990s both showed that commonly used assessments and ventilator weaning techniques were often associated with several days of delayed ventilator discontinuation. Moreover, recent trials of protocol-driven ventilator discontinuation procedures have clearly demonstrated that traditional standard care is often associated with significant delays in ventilator withdrawal.
