Clearly Comfortable
Reliably Mask-Free
The ProSoft® series of Hi-VNI® nasal cannulas offers a soft, safe, and reliable alternative for a wide patient acuity range.
Unlike commodity high flow oxygen devices (HFNC), Hi-VNI Technology is FDA cleared for use with respiratory distress patients, including high acuity hypercapnic patients.

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.
Learn Why Cannula Size Matters
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.

Soft on patient skin
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
