Capnography is undertaken by the two-in-one nasal cannula. It carries out pressure-monitoring, along with CO2 sampling. Color-coded tubing accounts for differentiation, for preventing misconnection. The latex-free and soft material offers greater relaxation and versatility, besides reducing irritation of skin. Kinking and tangling are eliminated, owing to designs of star lumen and twin tubing. Condensation and humidity is restricted from entering the equipment, owing to hydrophobic filter, thereby preventing infection and damage.
