Dynamics of carbon dioxide elimination following ventilator resetting.


BACKGROUND Carbon dioxide elimination (VCO2) at steady state corresponds to the metabolic rate. A change in tidal ventilation will lead to a transient response in VCO2 if other determinants of VCO2 are constant. This principle may be applied in the critical care unit to reset ventilators. OBJECTIVE To define and characterize the transient response of VCO2… (More)
