Abstract:
The survey results of the VIPs membership described in this article add qualitative information to the growing body of scientific knowledge on weaning patients off ventilators. Clearly, quantitative studies exploring the efficacy of different weaning practices across the continuum must be done if we are to accurately compare practices and prescribe the "when" and "how" of weaning. To this end, the Third National Study Group is revising the proposed weaning model and model in order to further elucidate the state of the art and science of weaning.
