The primary objective of the study is to describe the pressure patterns during esophageal and tracheal ventilation and to validate the diagnostic algorithm.

Condition Intervention
Esophageal Intubation
Other: tracheal ventilation with regular tube
Other: ventilation after intubation with special tube

Study Type: Observational
Study Design: Observational Model: Case Control
Time Perspective: Prospective
Official Title: Analysis of the Spirometry Pattern in Esophageal Intubation

Further study details as provided by University Medical Centre Groningen:
