Accuracy of acoustic respiration rate monitoring in pediatric patients.

Background: Rainbow acoustic monitoring (RRa) utilizes acoustic technology to continuously and noninvasively determine respiratory rate from an adhesive sensor located on the neck.

Objective: We sought to validate the accuracy of RRa, by comparing it to capnography, impedance pneumography, and to a reference method of counting breaths in postsurgical children.

Methods: Continuous respiration rate data were recorded from RRa and capnography.
