Effects of Orifice Plate as a Flow Sensor in an Endotracheal Tube on the Ability of Elimination CO2 during HFJV—Animal Study

High-frequency jet ventilators lacking flow monitoring systems, and information about supplied tidal volumes are still missing. This complicates the jet ventilator’s initial setting; at the same time, it complicates the line of the high-frequency ventilation itself. Therefore, an experimental flow sensor (orifice plate) was designed and placed in the ETC (endotracheal tube). Laboratory tests have confirmed the solution’s functionality, but it was necessary to verify the practical applicability for the clinical environment. The experiment shows that the flow sensor is used only for research purposes or when using functional monitoring of chest excursions.
