Versatile Sampling Line Technology for Existing Compatible Third-party Capnography Monitors

The NomoLine-O family of sampling lines shares all the advantages of NomoLine® “no moisture” sampling technology with the addition of a single-twist luer connector. This addition delivers out-of-the-box compatibility with existing compatible third-party capnography devices — making conversion easy and efficient while reducing the costs associated with new monitoring equipment. Like NomoLine sampling lines, NomoLine-O lines are available for intubated and non-intubated patients in low- and high-humidity applications and for all patient populations, including neonatal patients.
