What is a RAM Cannula and How is it Used?
A RAM cannula is a specialized medical device designed for delivering oxygen or non-invasive ventilation, especially for infants, children, and sometimes adults who require respiratory support. Unlike traditional nasal cannulas, the RAM cannula features soft, flexible prongs and a unique design to optimize patient comfort and the effective delivery of oxygen or air from various respiratory devices.
Understanding how to use a RAM cannula properly can make a significant difference in the quality of respiratory support provided and the comfort of the patient. Let’s break down everything you need to know about the RAM cannula—its purpose, usage, benefits, challenges, and best practices.
How the RAM Cannula Works
The RAM cannula acts as an interface between the patient and the oxygen or ventilatory support system. Its design enables both low and high flow oxygen therapy, as well as non-invasive positive pressure ventilation (NIPPV). Here’s how it functions in simple terms:
- Oxygen or air is delivered through soft nasal prongs into the patient’s nostrils.
- The prongs are positioned gently to minimize irritation or trauma.
- The cannula is connected to an oxygen or ventilation source using standard tubing.
- The flexible body and lightweight design promote comfort, allowing better tolerance, especially in pediatric patients.
Key Benefits of RAM Cannula
Some reasons why clinicians and caregivers choose the RAM cannula include:
- Comfort: Soft, flexible prongs reduce risk of skin breakdown and are gentle on sensitive noses.
- Versatility: Suitable for both low-flow and high-flow therapy, as well as use with various ventilation machines.
- Secure Fit: Different sizes and a close fit minimize air leaks.
- Reduced Mouth Leaks: Designed to minimize air leakage that can compromise therapy effectiveness.
- Improved Tolerance: Smaller, lighter, and less obtrusive than many alternatives, making it ideal for neonates and infants.
Step-by-Step Guide: How to Use a RAM Cannula
Here’s a simple process for effectively using a RAM cannula:
- Choose the Correct Size
- Available in multiple sizes for prematures, infants, children, and adults.
- Size selection is based on nostril width and patient age/weight.
- Inspect the Cannula
- Check for any defects or blockages before use.
- Ensure the nasal prongs are soft and intact.
- Attach to Oxygen or Ventilator Source
- Connect the tubing from the drive source (oxygen concentrator, wall supply, or ventilatory device) securely.
- Follow manufacturer instructions for connection.
- Prepare the Patient’s Nose
- Gently clean the child’s or patient’s nose to reduce the chance of irritation.
- If needed, use a thin layer of barrier cream to protect skin around nostrils.
- Insert the Cannula
- Position the breathing prongs just inside the nostrils—do not force deeply.
- The prongs should “float” at the entrance, providing a good seal without pressure.
- Adjust and Secure
- Use the built-in ear loops or an adhesive to secure the cannula.
- Check that the tubing is not pulling against the cannula.
- Ensure the cannula is not kinked or twisted, which could restrict airflow.
- Adjust Oxygen or Flow Settings
- Set the prescribed oxygen flow rate or ventilatory settings.
- Start with the recommended flow and titrate as per clinical order.
- Monitor the Patient
- Observe for comfort, skin redness, or any respiratory distress.
- Regularly re-evaluate the prong fit and the condition of the skin.
- Monitor oxygen saturation levels to ensure adequate therapy.
Typical Applications of the RAM Cannula
The RAM cannula is widely used for:
- Neonatal and Pediatric Care: Frequently used in NICUs for premature infants and newborns who need supplemental oxygen or non-invasive ventilation.
- Home Oxygen Therapy: Suitable for children requiring long-term oxygen at home due to chronic respiratory or cardiac conditions.
- Non-Invasive Ventilation: Interfaces with CPAP and BiPAP devices, providing a less irritating alternative to face masks or traditional cannulas.
- Transport Situations: Effective during hospital transfers due to its secure fit and comfort.
Benefits and Advantages in Patient Care
Using a RAM cannula can offer unique advantages:
1. Enhanced Comfort
- Reduces nasal irritation and pressure sores.
- Enables easier feeding and bonding for infants.
2. Effective Non-Invasive Support
- Delivers both high and low flow oxygen therapy or pressure ventilation.
- Can be used as an interface for CPAP, BiPAP, or other non-invasive ventilation techniques.
3. Improved Outcomes
- Patients often tolerate RAM cannulas longer than firm-pronged or face mask alternatives.
- Reduced need for sedation in pediatric or neonatal populations.
Challenges and Considerations
While the RAM cannula presents many benefits, there are also factors to watch for:
- Air Leak: If the cannula is too small or incorrectly positioned, oxygen may escape, lessening the therapy’s effectiveness.
- Skin Care: Close monitoring is needed to avoid irritation or breakdown, especially in premature infants.
- Sizing: Incorrect size selection can reduce efficacy.
- Training: Caregivers and healthcare staff need proper training to use and secure the cannula correctly.
- Not for All Patients: Severe respiratory distress or blocked nasal passages may require alternative methods.
Practical Tips and Best Practices
Here are some real-world tips to help you get the most from a RAM cannula:
- Measure Correctly: Use a sizing guide or ask your care team for proper measurement to select the right cannula size.
- Secure Gently: Avoid over-tightening or taping, as excessive pressure can cause skin breakdown.
- Inspect Frequently: Check the site at least every shift, and more often for sensitive skin.
- Humidification: Use humidified oxygen or air when flow rates are moderate to high to prevent dryness and improve comfort.
- Regular Cleaning/Replacement: Replace the cannula per manufacturer guidelines or if it becomes visibly soiled.
- Parental Education: For home care, teach parents or caregivers signs of poor fit (redness, leaks) and warn them when to call for help.
Cost Tips and Shipping Advice
- Cost Variation: RAM cannula pricing varies by size and supplier. Pediatric sizes may be similar or slightly more due to specialized design.
- Bulk Orders: Care facilities or clinics may benefit from bulk purchasing for discounts.
- Shipping: When ordering online, compare shipping costs across suppliers, especially for international orders which may increase total cost.
- Local Suppliers: Check with home healthcare companies, hospitals, or specialty pharmacies; local pickup or delivery can save on shipping fees.
Summary
The RAM cannula is a flexible, comfortable, and effective way to deliver low or high flow oxygen, as well as non-invasive ventilatory support. Its soft prongs, secure fit, and adaptability make it a popular choice in both hospital and home settings, particularly for infants and children. Successful use requires correct sizing, proper positioning, and skin monitoring. With the right approach, the RAM cannula can significantly improve patient comfort and therapy outcomes.
Frequently Asked Questions (FAQs)
What is a RAM cannula used for?
A RAM cannula is used to deliver supplemental oxygen or non-invasive ventilation to patients, especially newborns and infants. It’s commonly used in hospitals (NICUs, pediatric wards) and at home for chronic respiratory conditions.
How often should I replace a RAM cannula?
Generally, RAM cannulas should be replaced per manufacturer guidelines or sooner if they become soiled, damaged, or if skin irritation is noted. In a hospital, this might be every 1-7 days depending on condition and use.
How do I know what size RAM cannula to use?
Choose a size based on the diameter of the patient’s nostrils and the age/weight of the patient. Most brands provide a sizing chart. Prongs should fit comfortably at the entrance of the nostrils without stretching or compressing the skin.
Can the RAM cannula be used at home?
Yes, RAM cannulas are frequently used in the home setting for children who require ongoing oxygen or non-invasive ventilatory support. Proper caregiver training on use and monitoring is vital for home safety.
Is a RAM cannula better than a traditional nasal cannula or mask?
In many cases—particularly for children and infants—the RAM cannula offers improved comfort, reduced skin breakdown, and better tolerance compared to traditional cannulas or masks. The choice depends on patient needs and therapy goals, so your healthcare provider can recommend the best option.
