What is the recommended method for delivering oxygen to a child exhibiting tripoding?

1. Bag-mask ventilation

2. Non-rebreather mask

3. CPAP therapy

4. Nasal cannula

The correct answer is: Non-rebreather mask

Delivering oxygen effectively to a child exhibiting tripoding—a position often adopted to optimize breathing, typically indicating respiratory distress—requires an approach that maximizes oxygen delivery and minimizes effort. A non-rebreather mask is the recommended method in this scenario because it can provide a high concentration of oxygen. The mask allows the child to breathe in oxygen directly from a reservoir bag while using a one-way valve to prevent exhaled air from mixing with the incoming oxygen, ensuring that the child receives the highest possible concentration of oxygen. This choice is particularly suitable for children in respiratory distress, as it supports their rapid oxygen needs without placing additional stress on their respiratory system. A non-rebreather mask can typically deliver concentrations between 90-100% of oxygen, which is crucial for children who are struggling to breathe effectively. In contrast, other methods such as nasal cannula provide lower concentrations of oxygen and are less effective in acute situations where high oxygen delivery is essential. Techniques like bag-mask ventilation may be better suited for those requiring artificial ventilation rather than for those who are still able to breathe on their own but need supplemental oxygen.
