ENDOTRACHEAL TUBE PRESSURE MONITORING SYSTEM AND METHOD OF USING SAME

摘要

An endotracheal tube pressure monitoring system (10) for an endotracheal tube (20) having at least one pressure line (50) in fluid communication with a major lumen (23) of the endotracheal tube; a purging subsystem (80) in fluid communication with at least one of the pressure lines; and a pressure monitoring subsystem (60) in operative communication with each respective pressure line to monitor the pressure of fluid within each respective pressure line. Each pressure line that is in fluid communication with the purging subsystem being selectively purged when the pressure monitoring subsystem determines the respective pressure line has become obstructed. Purging the pressure line maintains the patency of the pressure line so that accurate pressure measurements within the endotracheal tube can be obtained for calculation of parameters in lung mechanics.
