Small Bore Compressor

Vapotherm’s small bore cannula was designed with high velocity in mind

A smaller diameter cannula increases velocity to more efficiently flush CO2 at lower and more comfortable flows.

A Variety Of Sizes Ensures the Perfect Fit For Your Patients

8 sizes are available from neonate to adult long with 4 inches of added lariat length to improve fit and comfort for larger patients. Each size is clearly color-coded for fast identification. No proprietary adhesive support is required.
