Gas Supply, Demand and Middle Ear Gas Balance -- Preliminary Protocol

Completed · Not applicable

Conditions studied: Middle-ear Function

In brief

The purpose of this study is to gather more information on Eustachian tube function and middle-ear pressures during flying. Ten subjects with tympanostomy tubes (plastic tubes inserted in the eardrums) in their ears or holes in their ear-drums will undergo flight simulation in a pressure chamber. Their middle-ear pressures and Eustachian tube function will be monitored at various chamber pressures.
