Tracking tidal volume noninvasively in volunteers using a tightly controlled temperature-based device: A proof of concept paper.

Introduction: There is a paucity of noninvasive respiratory monitors for patients outside of critical care settings. The Linshom respiratory monitoring device is a novel temperature-based respiratory monitor that measures the respiratory rate as accurately as capnography.

Objectives: Determine whether the amplitude of the Linshom temperature profile was an accurate, surrogate and qualitative metric of the tidal volume (V ) that tracks V in healthy volunteers.
