This adult nasal cannula combines oxygen delivery with simultaneous CO2 sampling through a Pull N' Peel design that resists tangling and maintains sampling accuracy. The super-soft PVC construction minimizes pressure and friction on ears and cheeks, protecting skin integrity during extended use. The 7-foot tubing features a universal O2 connector compatible with most flowmeters, plus male or female Luer connectors for flexible setup. Latex-free for patient safety.
