Correlation Between PaO2/FIO2 and Peripheral Capillary Oxygenation/FIO2 in Burned Children With Smoke Inhalation Injury.

Objectives: Determine whether the peripheral capillary oxygenation/FIO2 ratio correlates with the PaO2/FIO2 ratio in burned children with smoke inhalation injury, with the goal of understanding if the peripheral capillary oxygenation/FIO2 ratio can serve as a surrogate for the PaO2/FIO2 ratio for the diagnosis of acute respiratory distress syndrome. Design: Retrospective chart review. Setting: Shriners Hospitals for Children-Galveston. Patients: All burned children with smoke inhalation injury who were admitted from 1996 to 2014 and had simultaneously obtained peripheral capillary oxygenation, FIO2 and PaO2 measurements. Interventions: None. Measurements and Main Results: Two hundred seventy-three patients (63% male, 8 +/- 5 yr, 53% +/- 24% total body surface area burns) were analyzed. Peripheral capillary oxygenation/FIO2 ratios were divided into four subgroups based on peripheral capillary oxygenation values (
