Surely air perfusion gives an unreliable pressure recording?
Yes, if you want to measure pressure accurately, as air is too compressible to transmit large pressures faithfully to an external transducer. For swallow monitoring though, all that is needed is recognition of the occurrence of a pharyngeal pressure wave. Our unique air perfusion feature, developed by us, detects pharyngeal peristalsis and is the best way to monitor swallowing.
