The O2/CO2 Nasal FilterLine breath CO2 sampling line enables continuous non-intubated monitoring of etCO2 when nasal - only sampling is preferred and oxygen delivery is required. Unique O2 delivery system (up to 5L/min) 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
