Westmed was the first company to provide a total solution for maximizing patient comfort while virtually eliminating ear and facial ulcers resulting from high interface pressure from hard PVC (polyvinylchloride) nasal cannulas. Westmed product development engineers created a unique and proprietary elastomeric polymer.
Comfort Soft Plus® is highly elastic and relieves pressure on and behind the ears, thereby preventing pressure ulceration. Conventional PVC cannulas are hard and create considerable friction and shear forces when dragged across the skin causing breakdown.
