What Is Transdiaphragmatic Pressure?

The transdiaphragmatic pressure is measured by placing a thin-walled balloon transnasally at the lower end of the esophagus, allowing reflection of the changes in pleural pressure. Then, a second balloon manometer is placed in the stomach to measure changes in intra-abdominal pressure.

How is Transdiaphragmatic pressure measured?

The test is performed by placing an esophageal catheter with an esophageal balloon and a gastric balloon. The difference between the pressures measured at the 2 balloons is the transdiaphragmatic pressure. Patients with diaphragmatic dysfunction and paralysis have a decrease in maximal transdiaphragmatic pressure.
