Researchers complete first human trial on viability of enteral ventilation

If this was enough to temporarily replace breathing I wonder how that would feel if you were otherwise healthy. I imagine not breathing would instinctively feel quite strange and even distressing.

From the littlei know from a breath holding workshop I did awhile ago (for trying to get into freediving) it's the carbon dioxide build up in our blood that gives us the urge to breath, and not the lack of oxygen. If this method allowed for the removal of carbon dioxide from the blood then holding your breath might not even be discomforting.

Edit: goodells explained it better!
