In the previous issue of Critical Care, Rose and colleagues report the results of a survey on the frequency with which ICU nurses are involved in decision-making in ventilator management. About 63 to 88% of the decisions were made by nurses in collaboration with physicians, and as much as 68% of ventilator adjustments were performed by nurses independent of physicians. Nurse involvement in decision-making was twice as likely in ICUs that use weaning protocols. The ICU nurse performs many roles, the most important being the continuous observation of a patient. The diversion of a nurse's attention from constant vigilance by performing tasks of no benefit, such as the use of weaning protocols, would be a most unfortunate turn of events.
