A comparison between two methods of measuring pressure in the pharyngeal airway: transducer probe versus open catheter

Abstract: A new multi-transducer probe system for measuring pharyngeal pressures was compared with an established open catheter system. Pharyngeal pressure measurements were made at the same time, and site, in subjects awake, at unmodified and with artificially increased nasal airway resistances, and during sleep documented by polysomnography. The two systems yielded almostidentical results. It is anticipated that the multi-transducer probe system will prove of clinical value.

“…Dies war zu Beginn der Messungen von untergeordneter Bedeutung, da die untersuchten Patienten alle unter einem schweren Schlafapnoesyndrom litten und trotz Ballonsonde ohne Schwierigkeiten schliefen. Die Zuverlässigkeit der Mikrotip-Katheter wiesen Panizza und Finucane für die Ösophagus-und Tvinnereim et al für die Pharynxmanometrie sowohl im Wachzustand als auch im Schlaf nach [106,107]. Chervin et al und Skatvedt et al zeigten anhand guter Studien, dass ca.…”
