Working with respiratory waveforms: how to use bedside graphics.

Abstract

Respiratory waveform graphics packages are available on many ventilators. Despite the prevalence of the waveforms, accurate interpretation and clinical application are not widespread. In fact, many clinicians find the waveforms confusing and choose to ignore them. This article provides a straightforward description of how to interpret the waveforms and suggests ways that the information might be used to improve clinical outcomes.
