Abstract

The authors have advanced an algorithm that can use measurements of pressure and flow entering a standard flexible patient tubing circuit during clinical ventilation and predict pressures and flows actually delivered to a patient. For volume ventilation and step, ramp, or sinusoidal waveforms, predictions are within 5% of truth for most of the inspiratory cycle. From these data, the authors can then accurately track respiratory dynamic resistance and elastance
