Continuous non-invasive monitoring of tidal volumes by measurement of tidal impedance in neonatal piglets.
BACKGROUND: Electrical Impedance measurements can be used to estimate the content of intra-thoracic air and thereby give information on pulmonary ventilation.Conventional Impedance measurements mainly indicate relative changes, but no information concerning air-volume Sculptures is given.The study was performed to test whether a 3-point-calibration
