Short summary
In artificial ventilation of neonates uncuffed endotracheal tubes are commonly used. The unknown leakage hampers the detection of spontaneous breathing. A new method to measure respiration by using antennae has recently been presented. A respective setup is investigated numerically and experimentally. Both approaches show that the method seems capable of allowing a contactless triggering to synchronize ventilation. The results are compared to derive a better understanding of influencing factors.
