tracheal tube cuff manometry
Pronunciation: man-OM-eh-tree
Measurement technique for monitoring endotracheal tube cuff pressure to prevent tracheal injury in pediatric patients.
Full Definition
Tracheal tube cuff manometry is the practice of measuring and monitoring endotracheal tube cuff pressures using a calibrated pressure gauge or monitor. In pediatric anesthesia, this technique is particularly critical because children are more susceptible to tracheal injury from excessive cuff pressures due to their smaller, more compliant airways. The goal is to maintain cuff pressures between 15-25 cmH2O to provide an adequate seal while preventing mucosal ischemia, tracheal erosion, or stenosis. Regular monitoring is essential as cuff pressures can change due to patient positioning, surgical manipulation, or temperature changes.
Usage
Usage note: Do not hyphenate the compound noun form.
