Abstract/OtherAbstract:
It is recommended to maintain cuff pressure (CP) within a defined range of 20 to 30 cm H₂O. Excessive cuff inflation is a recognized risk factor for tracheal injury and stenosis. Insufficient CP can increase the leakage of colonized sub-glottic secretions above the cuff, contribute to air leak, and increase the risk for accidental extubation. Techniques such as palpation of the pilot balloon or performing routine checks using the minimal occlusive volume (MOV) technique, have not provided protection against these risk factors. Cuff pressure must be monitored to ensure that the pressure remains within the recommended range. Unfortunately the existing techniques and devices for monitoring CP are inadequate and do not lessen the risk factors associated with artificial airways. We designed a novel device to continuously measure and display CP and evaluated its effectiveness in laboratory models. We describe a device that is designed to comply with the American Thoracic Society and Infectious Disease Society's ventilator associated pneumonia (VAP) Level II Recommendation for maintaining CP above 20 cm H₂O.
