A cannula is a slender, flexible tube designed for delivering or removing fluids or gases from the body. This often involves external applications, such as providing supplemental oxygen. Proper application and consistent wear of a cannula are important for its effectiveness and for maintaining user comfort.
Preparing for Cannula Use
Before applying a cannula, ensure all necessary supplies are readily available and in good condition, including the cannula, connecting tubing, and oxygen source or pump. Inspect equipment for damage like kinks, cracks, or blockages. Thoroughly wash your hands with soap and water to minimize microbe transfer. For nasal cannulas, gently clean and dry the skin area where it will be placed.
Step-by-Step Cannula Application
First, ensure the cannula is connected to its oxygen source or associated device. For a nasal cannula, insert the two prongs into your nostrils, ensuring they curve downward. Guide the tubing from each side of your face over your ears, similar to wearing eyeglasses. A sliding adjuster, or bolo, positioned under your chin helps secure the tubing. Adjust this slider for a snug fit that keeps the cannula in place without feeling overly tight.
Achieving a Secure and Comfortable Fit
Once in place, fine-tune the cannula’s position to prevent irritation and dislodgement. The tubing should rest comfortably over your ears, jaw, and chin, allowing enough slack to fit two fingers between the tubing and your chin. If tubing causes pressure or rubbing behind the ears, consider using soft padding or specialized ear wraps. For irritation around the nostrils, a water-based moisturizer can provide relief; avoid petroleum-based products as they can degrade materials and interfere with oxygen delivery. Tubing clips can also secure the long oxygen line to clothing, reducing tangling and pulling on the cannula.
Cannula Care and Maintenance
Consistent cannula and skin care is important for hygiene and equipment longevity. Daily cleaning of nasal prongs with mild soap and water prevents bacterial buildup. For weekly cleaning, soak some components in a mixture of ten parts water to one part vinegar, then rinse thoroughly and air dry. Cannulas are disposable; replace every two to four weeks, or sooner if discolored, stiff, or damaged. If you have a cold or flu, replace the cannula after symptoms resolve to prevent reinfection.
Safety and Troubleshooting
Safety guidelines are important when using a cannula, especially with oxygen delivery systems; always ensure tubing is free from kinks or blockages that impede gas flow. If using oxygen, observe fire safety precautions: avoid open flames, smoking, and heat sources near the equipment. Keep the cannula and tubing away from pets and young children to prevent damage or entanglement. If you suspect an issue with oxygen flow, such as a lack of sensation from the prongs, check the connection to the source and inspect for visible damage or kinks. Should you experience symptoms like increased shortness of breath, changes in breathing, or bluish lips or fingertips, contact a healthcare provider immediately.
