Pragmatic Investigation of optimaL Oxygen Targets Trial
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.

Study Design
- Phase
- N/A
- Study Type
- Interventional
- Allocation
- Randomized
- 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).
- Primary Purpose
- Treatment
- Masking
- 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.
Arm Groups
Arm | Description | Assigned Intervention |
---|---|---|
Active Comparator Lower 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 90% (range 88-92%). |
|
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%). |
|
Active Comparator Higher 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 98% (range 96-100%). |
