Our goal this semester is to develop a pressure-regulating system for an endotracheal tube cuff that will not allow intracuff pressure to exceed 25 cm H2O pressure. Overinflation of the cuff (which provides a tight seal between the endotracheal tube and the patient’s trachea) is a common problem. The excess pressure can cause many complications, especially in children.
We have finished production of the prototype and have completed testing. We are finishing the final paper and notebooks.
