CapnoVue capnography masks improve capnography performance with oral-nasal sampling for mouth breathers and upper GI cases. They provide higher oxygen delivery for patients who require aggressive oxygenation. Luer ports, located at both expiratory ports, separate CO2 from O2 for clean signals. The CapnoVue scope features a port for endoscopes and bronchoscopes. The standard mask is usable in all other cases.
