Abstract

Embodiments disclosed herein are directed to a dynamic pressure response system for fully automated clearing of dependent loops from a fluid drainage system. Fluid drainage systems include a flexible drainage tube providing fluid communication with a collection container. Dependent loops can form within the tube leading to pooling of urine and provide an increased risk in CAUTI. Dynamic pressure response systems can automatically detect the presence of dependent loops and provide a low-rate positive air pressure to clear the columnized fluid. Further, the system can automatically detect mixed fluid states when a noise level of pressure signals increases, the system can then provide high-rate positive air pressure to clear mixed fluid state liquid from the tube lumen.
