CLINICALLY RELEVANT DISCOVERY RECOGNIZED DURING SIMULATOR TRAINING SESSION - FREESTANDING PEEP VALVE SOLVES PROBLEM OF INCOMPETENT EXHALATION UNIDIRECTIONAL VALVE IN AN ANESTHESIA CIRCLE BREATHING SYSTEM

While conducting a case-based teaching session using a full-scale simu lator, the authors discovered that placement of a unidirectional PEEP valve in the expiratory limb corrects the gas flow pattern, despite an exhalation valve failure.
