Small bore cannula

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.

Premature and neonate cannula sizes are not approved for use with HVT 2.0.

Pressure ulcers occur in 70% of patients receiving 48 hours of ventilation. [1] Nasal cannulas have up to a 47% incident rate of pressure ulcers. [2] Soft cannulas have been shown to reduce pressure ulcers. [3]
