Differences in lung function after the use of 2 extrication systems: a randomized crossover trial.

Objectives: The main purpose of this study in healthy volunteers was to compare the lung function effects of 2 extrication devices that use spinal vests: the Kendrick Extrication Device (KED) and the Ferno KED-XT board.

Material And Methods: Randomized crossover trial in 50 healthy adult volunteers. The subjects were placed in the KED and KED-XT devices for 5 minutes each and rested for 10 minutes between devices.
