Respiratory - Oxygen Aids - Roscoe Medical Clear Comfort Cannula with 7' Kink : Nasal Cannulas from Roscoe are a comfortable and economical option for effective oxygen therapy. Made of extra-soft material and designed for adults, the Cannula provides comfort and maximum safety. When uncoiled, the supply tubing lies straight, minimizing pull on the cannula. Unlike traditional CPAP systems and tubes, there is no valve. Treatment with a Cannula is also considered a less invasive treatment than CPAP. Compared to CPAP, Cannula treatments are more suitable and better tolerated by patients and preferred by staff. This Cannula comes complete with 7' of supply tubing. This is one case of Cannulas which are packaged 50 per case. Less obtrusive than CPAP units, these fit comfortably over the ears. Cannula is disposable and intended for single patient use only. Tubing is crush-resistant, ensuring a safe and uninterrupted flow of oxygen. Not just for adults, the Cannula is also available in pediatric versions. All the tubing as well as the Cannula are Latex-free.
