Masimo - NomoLine


Moisture-wicking sampling lines for intubated and non-intubated patients in low- and high-humidity applications

Designed for low-flow applications, NomoLine sampling lines can be used in a variety of clinical scenarios for all patient populations. NomoLine sampling lines are compatible with Masimo ISA™ gas analyzers , which provide capnography and anesthetic gas measurements. Available in both low- and high-humidity configurations, these sampling lines can be used on both intubated and non-intubated patients.



NomoLine-O - Split-flow pathways cannula

Split-flow cannula design

  • Reduces gas mixing, facilitating accurate EtCO2 measurements
NomoLine-O - Moisture-wicking tubing

Patented moisture-wicking technology

  • Water-free sample provides accurate gas measurements
NomoLine - Single-twist connector

Low-flow Sampling Rate

  • Allows for capnography measurements on patients with small tidal volumes and high respiratory rates
NomoLine-O - Ergonomic Cannula

Ergonomically designed cannulas

  • Fits the contours of the face to minimize pressure, for patient comfort
NomoLine-O - Close-up of hydrophobic bacterial filter

Hydrophobic bacterial filter

  • Prevents contamination of the gas analyzer and extends the life of the module by preventing water intrusion
NomoLine-O - Close-up of star-shaped lumen tubing

Star-shaped lumen O2 delivery tubing

  • Allows for continuous, accurate O2 supply even if kinked

How NomoLine Works

How NomoLine Works

  • Gas and condensed moisture from the patient’s expired breath enters the Nomo Section through the gas sample tube
  • Condensed moisture and aspirated water are separated and collected using a hydrophilic absorbent
  • Water molecules are diffused from the hydrophilic absorbent through the Nomo polymer cover
  • Long-term use is possible as the water diffused through the Nomo polymer cover continuously evaporates into the surrounding air
  • A hydrophobic bacteria filter protects the gas module from water intrusion and cross-contamination
