Pilot Evaluation Comparing Regional Distribution of Ventilation During Lung Expansion Therapy

Completed · Not applicable

Conditions studied: Ventilation, Breathing, Atelectasis

In brief

The primary purpose of this study is to determine if there is a significant difference in regional distribution of ventilation when comparing eupneic tidal ventilation with Incentive Spirometry (I.S.) and EzPAP® lung expansion therapy in healthy adult human subjects. Electrical impedance tomography (EIT) will be used to measure regional distribution of ventilation during resting tidal ventilation and during lung expansion therapy.
