Summary

Respiratory distress is a common problem in an intensive care unit. There are multiple mechanisms that are used to help patients who are in respiratory distress including mechanical ventilation, continuous positive airway pressure (CPAP), bilevel positive airway pressure (BiPAP), high flow oxygen, and oxygen supplementation through nasal cannula or a facemask.

The purpose of this study is to evaluate the mechanism by which Vapotherm, a high flow oxygen system, provides breathing support. Vapotherm provides high flow oxygen at different flow rates, meaning one can increase the amount of oxygen flow to help with breathing support. The investigators believe that this high flow oxygen system may provide similar breathing support that a continuous positive airway pressure machine (CPAP) machine does.

Interventions

DEVICE

HFNC

Graded high flow nasal cannula oxygen at 10, 20 , 30, and 40 liters per minute (LPM) to each subject and end-expiratory lung volume measured by respiratory inductive plethysmography.

DEVICE

CPAP

Graded contiuous positive airway pressure at 5, 10 , 15, and 20 cm H2O applied to each subject and end-expiratory lung volume measured by respiratory inductive plethysmography.
