Learn how to clean, inspect, and store your ETCO2 nasal cannula to ensure accurate readings and patient comfort. Follow these simple steps.

Quick Answer

Proper ETCO2 cannula care involves gentle cleaning after each use, thorough drying, and storing in a clean, dry place to prevent contamination and maintain accurate readings.

Why Care Matters for Accuracy

A clean ETCO2 cannula is essential for reliable capnography readings. Dirt, moisture, or blockages can interfere with gas sampling, leading to inaccurate CO2 measurements. Regular care helps ensure patient safety and extends the life of the device.

While many cannulas are single-patient use, proper maintenance between uses is important for home care or extended monitoring situations. Always follow your facility's infection control guidelines and the manufacturer's instructions.

Know Your Cannula Type

The Salter Labs® ETCO2 nasal cannula features a 3-channel tube design that resists kinking, reducing the risk of oxygen or EtCO2 flow loss. This design requires careful handling to preserve the internal channels. Avoid bending or twisting the tubing during cleaning and storage.

Different cannula models may have specific care requirements. For example, the Salter Labs® Adult Curved Prongs with Tubing Low Flow Rate includes a non-flared tip and trumpet connector, which should be cleaned gently to avoid damage.

Step-by-Step ETCO2 Cannula Care

Rinse with warm water: Immediately after use, rinse the cannula prongs and tubing under warm (not hot) running water to remove mucus, debris, and secretions. Avoid using hot water as it can damage the plastic. Check that water flows freely through the tubing; if not, gently squeeze to clear blockages.
Clean with mild soap: Use a mild dish soap or medical-grade cleaner. Gently rub the prongs and tubing with your fingers or a soft cloth. Do not use harsh chemicals, alcohol, or abrasive brushes, which can degrade the material. Rinse thoroughly to remove all soap residue, which could irritate the patient's skin or nasal passages.
Disinfect if needed: For home use, a diluted bleach solution (1 part bleach to 10 parts water) can be used, but only if recommended by your healthcare provider. Soak for 5 minutes, then rinse thoroughly with sterile or distilled water. For clinical settings, follow your facility's disinfection protocol. Always air-dry completely after disinfection to prevent moisture buildup.
Air-dry completely: Hang the cannula or lay it flat on a clean, dry towel. Allow it to air-dry completely before storage. Do not use a hairdryer or place it in direct sunlight, as heat can warp the tubing. Ensure no moisture remains inside the tubing; shake out any droplets before drying.
Inspect for damage: Check the prongs, tubing, and connectors for cracks, kinks, or blockages. If the cannula is damaged, discard it and replace with a new one. Do not attempt to repair it. Regular inspection helps catch issues early and ensures accurate readings.
Store in a clean, dry place: Place the dry cannula in a sealed plastic bag or its original packaging. Store it away from direct sunlight, heat sources, and chemicals. Keep it out of reach of pets and children. Label the bag with the patient's name and date if storing for reuse.
