Purpose

Mechanical ventilation of ICU patients universally involves titration of the fraction of inspired oxygen (FiO2) to maintain arterial oxygen saturation (SpO2). Despite decades of ICU practice, however, the optimal SpO2 target remains unknown. Current guidelines offer divergent recommendations as to the optimal SpO2 target. Therefore, we propose a 2,250-patient cluster-randomized cluster-crossover trial comparing a lower SpO2 target (90%; range 88-92%), an intermediate SpO2 target (94%; range 92-96%), and a higher SpO2 target (98%; range 96-100%) with regard to the outcome of days alive and free of invasive mechanical ventilation.

Intervention Model
Crossover Assignment
Intervention Model Description
In the PILOT trial, the entire study ICU will be assigned to a single SpO2 target (cluster-randomized) and the ICU will switch between lower, intermediate, and higher SpO2 targets every two months in a randomly generated sequence (cluster-crossover).

Single (Outcomes Assessor)
Masking Description
Observer bias will be minimized by use of objective endpoints collected in duplicate by [1] study personnel blinded to group assignment and [2] automated data extraction from the electronic health record.

Active Comparator
Intermediate SpO2 Target
During invasive mechanical ventilation in a study location, the fraction of inspired oxygen will be titrated to target an arterial oxygen saturation of 94% (range 92-96%).
  • Other: Intermediate SpO2 Target
    SpO2 target 94% (range 92-96%)
Active Comparator
Higher SpO2 Target
