# Table 28.3 Advantages and Disadvantages of Common Oxygen Administration Devices ## Method | O₂ Delivery | Advantages | Disadvantages | Nursing Implications ---|---|---|---|--- **Nasal Cannula (nasal prongs)** | Low concentrations; dependent on rate and depth of breathing | Patient can move about, eat, and talk while receiving oxygen. Most COPD patients can tolerate 2 L/min flow. | Restless patients can easily dislodge the prongs. Risk of skin irritation at the nares, ears, and cheeks. Flow rate 3 L and above requires humidification to prevent drying and irritation of nasal mucosa. | Prongs should be curved downward when inserted in the nose; check frequently because patients tend to replace the prongs incorrectly. Make sure prongs are patent. **Simple face mask** | Low to medium concentrations; 35%-50% can be achieved with a flow rate of 6-12 L/min. | Mask provides adequate humidification; delivers oxygen quickly for short-term therapy. | Discomfort and risk of pressure necrosis caused by a tight seal between the face and mask. | Wash and dry under the mask and wipe out the mask q 1-2 h. Mask must fit snugly. Straps at the ears may need to be padded to prevent irritation and possibly necrosis. **Partial rebreathing mask** | Higher concentrations; 40%-60% at flow rates of 6-10 L/min. | Mask is lightweight; reservoir contains 100% oxygen for breathing. One tab on the mask prevents limitation on the amount of exhaled CO₂ that is "rebreathed" by the patient. | Risk of pressure necrosis with long-term use. Cannot be used with high humidity. | **Non-rebreather mask** | Highest concentrations; 60%-90% can be achieved. | Delivers a high concentration of oxygen. One-way tabs on the mask prevent the patient from rebreathing exhaled CO₂. | Cannot be used with high humidity. Flow rate must be sufficient to prevent the bag from deflating during inspiration. | Mask should fit snugly; check skin contact areas for pressure necrosis. Flow of O₂ should be high enough that the bag does not deflate during inspiration. Check skin under the straps frequently. **Venturi mask** | Delivers consistent FiO₂ regardless of the breathing pattern. Concentration and liter flow are marked on the mask apparatus; available for 24%, 28%, 31%, 35%, 40%, and 50% O₂. | Mask can provide good humidification; good for delivering low, constant O₂ concentrations to the patient with COPD. | Discomfort and risk of skin irritation. Must be removed for eating, drinking, and taking oral medications. Talking is muffled. | Air ports must not be occluded. Check skin contact areas frequently. **Transtracheal catheter** | Delivers oxygen efficiently. | Flow requirement is reduced 60%-80%, increasing time that oxygen is available from portable source. Catheter is less visible. Less nasal irritation occurs. | Catheter replacement is an invasive procedure. Not appropriate for someone with excessive mucus production. | Patient and family education about catheter replacement. **Note:** The table above summarizes the advantages, disadvantages, and nursing implications for various oxygen administration methods.
