Has anyone used them for a period of time?What has been the results with your patients? What are the percentages with each liter flow used?Can you titrate a pt's liter flow down past 6 liters or do you have to switch over to a regular cannula ( low flow )

Hi Wheezer, are you referring to the vapotherm product for high flow gas delivery? We have honestly had great results with this type of system. COPD pt's love it! You can dial in exact FIO2's and flow rates up to 40 lpm (heated and humidified) We have had patients with low sats on Non-Rebreather masks, switched them to the vapotherm and within minutes saw an improvemnent in Sat's and WOB. Although the liturature does not state it, at flows near 40 lpm, a small amount of CPAP is applied. It seems like this CPAP helps to ventilate and oxygenate difficult patients.

Robin, you should absolutely be using heated humidity with the high flow nasal cannula. This is what makes their use both well tolerated and acceptable. Remember that this becomes a high flow device if it it exceeds one's minute ventilation and they are breathing primarily through the nose, particularily in the neonate population with the obligate nose breather.

With the super high liter flows, the fact that these cannulas more resemble high flow devices becomes apparent when you increase the delivered flow and are then able to wean the fiO2. The funniest/scariest thing that I've ever heard was while switching a 7 d.o. infant on a peds floor from a 2 l nc at 100% O2 to a VTNC @ 12lpm and 40% O2 was the therapist that was on said " why does this kid now require 40% O2 on the vapotherm when he only required 28% since he was on a 2l NC?"
