Clinical Evidence for Single Prong Oxygen Technology


Oxygen therapy performance systems are dependent on the patient’s ventilation systems and the oxygen delivery methods and devices. The following articles look at the various oxygen delivery devices to determine the performance of those systems with primary observation of comparing single prong oxygen delivery devices to dual prong oxygen delivery devices.

We found evidence that the single prong technology provided equivalent POX performances. In a 121 patient study, we found that the single cannula devices provided higher statistically significant POX readings when compared to dual prong POX readings across flow rate categories within a defined patient population and across both continuous and pulse delivery type devices.
