Smart CapnoLine H Plus and Smart CapnoLine H etCO2 breath sampling lines are designed for long duration monitoring for non-intubated patients who are either nose or mouth breathers. Patented Uni-junction™ design assures oral & nasal sampling even at low tidal volumes, with no dilution of waveform during O2 delivery Unique O2 delivery system enables effective oxygen therapy and reduces the O2 drying effect on sensitive mucus membranes Built in water-trap with hydrophobic filter prevents moisture from entering the monitor while maintaining the laminar flow and excellent waveform The filter design and small diameter of the circuit (1.0 mm I.D. microbore tubing) improve accuracy and response time For adult and pediatric patients Includes moisture reduction technology for long term use
