A Flow Sensor Suitable for Use With Split‐flow Ventilation—First Preclinical Data

Abstract: Volutrauma caused by artificial ventilation represents a major morbidity risk for premature infants. Our working group has recently developed an innovative "split-flow ventilation" system aiming at the reduction of tidal volumes (TVs). The main problem for the practical use of this system is the fact that conventional measurements of commercially available flow sensors are distorted by the split flow. In this study, we present the first preclinical data from testing an adapted flow sensor combination recognizi… Show more

“…As a result, the expiratory tidal volume is either significantly over‐ or underestimated, respectively. In principle, a flow sensor can be calibrated to a washout flow 11 . To enable such calibration, the washout flow should remain virtually constant; however, without a pump, such flows fluctuate greatly over the course of the breathing cycle in response to pressure changes.…”

“…Martin Wald et al. (50) of the University of Vienna (Vienna, Austria) described their work on a split‐flow ventilation system aiming at the reduction of tidal volumes to reduce volume overload trauma in particular in premature infants. With appropriate sensors, exact flow measurements were possible in the clinical setting.…”
