The Sunset high-flow soft nasal cannula delivers supplemental oxygen at 6 to 15 liters per minute, so it suits oxygen concentrators set to high-flow output. It maintains oxygen saturation without a mask, which many people find more comfortable for daytime use.
The 4 foot supply tube uses 6-channel safety tubing for steady delivery at higher flow rates. Sunset makes this cannula from a softer material, and it is made without natural rubber latex and without DEHP or phthalates.
The 4 foot length suits a bedside or close-range setup where you stay near the unit. If you want more room to move, a 7 foot version is also available.
High-flow output of 6 to 15 LPM is supported by higher-output units. You can see compatible equipment in our home oxygen concentrators collection. Most small portable concentrators do not reach 6 to 15 LPM.
