How can you be sure that a larger abdominal waveform, as compared with a smaller chest waveform, means that a client is breathing more abdominally than thoracically? Could this difference be due to discrepancies in the sensitivity of the sensors? This article describes a procedure for measuring the sensitivity of respiratory strain gauges and provides practical recommendations for accurate measurement and display of the relative expansion and contraction of the chest and abdomen.
