Comfort Plus™ oxygen nasal cannulas with curved nasal prongs are clear, lightweight and designed to ensure a comfortable fit for long-term use. The over-the-ear, "bolo-style" adjustable slide moves smoothly, yet provides a secure fit and allows maximum freedom of movement. The curved nasal prongs promote alignment of the cannula to fit naturally on the patient’s face, eliminating the irritating flap required with conventional-style cannulas. The Comfort Plus Soft Tip models come standard with 6-channel safety tubing to ensure uninterrupted flow of oxygen to the patient.
