Title
Validity of volumetric capnography for the quantification of dead space during flow-controlled ventilation with active expiratory flow
Author
Abstract
Flow-controlled ventilation (FCV) is an emerging method of controlled mechanical ventilation characterized by constant, active expiratory flow.1-3 The inspiratory flow pattern during FCV is similar to volume-controlled ventilation (VCV). During early expiration, gas flow is limited, while during late expiration, flow is expedited. In contrast to passive expiratory flow limitation, the expiratory time during FCV is controlled and generally shorter. FCV may result in improved CO2 clearance and a more homogeneous distribution of ventilation. Reduced dead space ventilation might explain these observations. Volumetric capnography (Vcap) has been validated for dead space measurements during passive expiration, but its use during active expiration has not been studied. We assessed the validity of volumetric capnography for the quantification of dead space ventilation during active, constant expiratory flow in a bench test.
