An accurate SpO2 value is critical in order to optimally titrate oxygen delivery to patients and to follow oxygenation guidelines. Limited prospective data exist on real-world performance of pulse oximeters in critically ill patients. The objective of this study was to assess accuracy and bias of the SpO2 values measured by several oximeters in hospitalized subjects. ⋯ We found significant bias and moderate accuracy between the tested oximeters and the arterial blood gases in the studied population. These discrepancies may have important clinical impact on the detection of hypoxemia and management of oxygen therapy.

The optimal spontaneous breathing trial (SBT) duration is not known for children who are critically ill. The study objective was to evaluate extubation outcomes between cohorts exposed to a 1- or 2-h SBT. ⋯ A 1-h SBT may be a viable alternative to a 2-h version for the average child who is critically ill. Further, a 1-h SBT may better balance extubation outcomes and duration of invasive ventilation for the general pediatric ICU population.
