Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In this trial the investigators will evaluate blood flow in common carotid artery of healthy subjects treated with Continuous Positive Airway Pressure (CPAP) Ventilation, comparing two different devices: oronasal mask versus Helmet. The hypothesis is that Helmet CPAP reduces carotid flow compared to oronasal mask.
