Comparison of Portable Oxygen Concentrators and Inspired Oxygen Levels in a Model of Respiratory Failure
Wall oxygen and standalone concentrators consistently outperformed POCs across most breathing conditions. While the CAIRE FreeStyle<sup>®</sup> Comfort<sup>®</sup> with autoSAT<sup>®</sup> offered relative advantages at high respiratory rates, most POCs may not adequately sustain oxygenation during exertion or stress. These findings inform home oxygen therapy decisions, emphasizing the importance of device selection based on respiratory demand. Clinical validation of these bench findings is warranted.
