Position of Esophageal Balloon in Patients With Mechanical Ventilation

NCT02446938 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 20

No results posted yet for this study

Summary

Transpulmonary pressure is frequently monitored in patients with mechanical ventilation. Right position of the catheter balloon is the key factor in accurate measurement. A simple method for confirming the balloon position will be validate in this study.

Conditions

  • Mechanical Ventilation

Interventions

PROCEDURE

Esophagus balloon catheter insertion.

Esophagus balloon catheter will be inserted and the position of the balloon will be confirmed by a air injection test.A bolus of 30 ml of air was injected to the gastric lumen of the catheter just next to the distal edge of the balloon, during the onset of end-expiratory phase. The presence of a positive disturbing wave (PDW) in esophageal pressure waveform to this air injection will be the indicator of the right balloon position.
