Implication

Centroid frequency enables stable diaphragmatic EMG quantitation; leaves open clinical translation in respiratory monitoring.

Structured PICO

P
Population
6 normal subjects
I
Intervention
Recording of inspiratory diaphragmatic EMG via esophageal electrodes and power density spectral analysis before and after band-pass filtering (20-1,600 Hz)
O
Outcome
Spectral characteristics of EMG and ECG signals and stability of power and frequency parameterssurrogate

Centroid frequency is a stable and reproducible parameter for quantitating the inspiratory diaphragmatic EMG spectrum, unaffected by tidal volume or inspiratory flow rate.
