esophageal pressure monitoring
Pronunciation: /ɪˈsɒfəʤiəl/
A technique using a balloon catheter placed in the esophagus to measure pleural pressure, providing accurate assessment of respiratory mechanics in mechanically ventilated patients.
Full Definition
Esophageal pressure monitoring involves the placement of a specialized balloon catheter in the patient's esophagus to measure esophageal pressure, which closely approximates pleural pressure. This technique provides respiratory therapists and clinicians with precise measurements of transpulmonary pressure, enabling more accurate assessment of lung compliance and chest wall mechanics. It is particularly valuable in patients with obesity, chest wall abnormalities, or acute respiratory distress syndrome, where traditional ventilator parameters may not accurately reflect lung mechanics. The data obtained helps optimize PEEP settings and ventilator strategies to improve patient outcomes.
Usage
Usage note: Always use 'esophageal' (American spelling) rather than 'oesophageal' in clinical documentation.
In Context
- "Esophageal pressure monitoring revealed that the optimal PEEP was 14 cmH2O to maintain positive transpulmonary pressure." — Critical care assessment
- "The respiratory therapist recommended esophageal pressure monitoring to guide ventilator management in this obese ARDS patient." — Clinical consultation note
