Summary

The goal of this study is to determine the relationship between esophageal pressure (Pes) and superimposed pressure (SP) in subjects with morbid obesity.

Conditions

Interventions

RADIATION

low-dose chest CT scan

The low-dose chest CT scan is now commonly used as a quick, painless, and non-invasive approach to screen for lung cancer. The radiation exposure from one low-dose CT scan of the chest (1.5 mSv) is comparable to 6 months of natural background radiation for a person living in the US.

DEVICE

insertion of esophageal balloon

The esophageal catheter is a flexible thin plastic tube with an air-filled balloon at the distal end. The tube will be placed through the nasopharynx after local anesthesia.
