End-tidal carbon dioxide monitoring for weaning patients: a pilot study.

This research pilot study evaluates the usefulness of capnography for patients being weaned from mechanical ventilation in a medical intensive care unit (MICU). The hypothesis that capnography would allow for more rapid weaning from mechanical ventilation, and require fewer arterial blood gases (ABGs) during the process, was found to be untrue. Several implications for critical care nursing practices were derived from the literature review and findings of this study.
