Abstract

The usual method of weaning mechanically ventilated patients from high FIO2 in our ICU, in which housestaff ordered all ventilator changes in an unstandardized manner (control group), was compared to a nurse-directed protocol that used a single arterial blood gas (ABG) analysis and multiple pulse oximetry measurements. The protocol required an ABG to be obtained upon the initiation of intubation/mechanical ventilation, followed by pulse oximetry measurements obtained in accordance with a standardized timetable. Decreases in FIO2 were guided by these results. It was concluded that a nurse-directed oxygen weaning protocol utilizing a combination of a single ABG and multiple pulse oximetry measurements was safe, reduced the need for ABGs, and decreased the duration of patient exposure to toxic oxygen concentrations.
