AirLife Adult EtCO2/O2 Filtered Divided Cannula with Nafion Tubing

Nafion is a selective polymer tubing used in the EtCO2 sample path for moisture management. Water vapor moves through the Nafion wall toward drier surrounding air, while the CO2 sample continues down the lumen to the monitor.² That reduces condensate forming inside the line (rainout) during extended monitoring, humidified oxygen, high-humidity environments, and longer ground or air transport—conditions where standard sample tubing is more likely to collect water and degrade the EtCO2 waveform. AirLife specifies Nafion options for extended use and high-humidity applications.²

Exhaled gas carries water vapor. On extended monitoring, humidified oxygen, or long transport, moisture can condense in the sample tubing (rainout) and impair the EtCO2 signal. AirLife specifies Nafion tubing for moisture management in high-humidity and extended-use applications.²

Use Nafion configurations for longer ground or air transports, humid environments, and longer continuous monitoring intervals. Use standard divided cannulas for shorter, routine EtCO2/O2 needs.²

Yes. It remains a divided EtCO2/O2 cannula; Nafion adds moisture management on the sample path.¹

This is the AirLife Reflective Series EtCO2 connector (SalterSTAT reflective), used with sidestream monitors that require a reflective gas-sample connection—not a standard Luer-only sample port.^C1 Common reflective-compatible platforms include:

• Stryker / Physio-Control LIFEPAK 12, 15, 20, 20e, and 35
• ZOLL Propaq and X Series
• Philips Tempus (and other Philips reflective-port configurations)
• Other reflective-port monitors in the AirLife compatibility set, including selected Philips, Medtronic / Covidien Microstream, Mindray, Datascope, HP, and Respironics systems

Always confirm your monitor’s sample-inlet type and cable before stocking; reflective lines will not fit a plain Luer inlet without the correct adapter path.
