Clinical Comparison of Flow Regulated Nasal Oxygen Delivery System (FRNDS) Cannula and Plethysmography Belts

"FRNDS is a novel cannula device that can both measure tidal volume (VT) in real time while simultaneously delivering air to the test subject.~After collecting data without any flow through the FRNDS cannula for 2 minutes, varying amounts of medical air ( 21% Fio2) starting with 2 Liters for two minutes , 4 liters for 2 minutes, 6 liters for two minutes and 8 liters for two minutes would be delivered while monitoring and recording data previously described with the FRNDS device."
