What is a common starting oxygen flow for an adult in distress when oxygen is available?

• A. 10-15 L/min via non-rebreather
• B. 6-8 L/min via simple mask
• C. 1-2 L/min via nasal cannula
• D. 2-4 L/min via nasal cannula

Answer: (D)

Start with the least invasive method and a modest flow to support oxygenation while you assess the patient. A nasal cannula is comfortable, keeps the patient able to talk and move, and lets you titrate oxygen up or down as needed. This approach provides enough oxygen for many adults in distress without overdoing it or creating the challenges that higher-flow devices bring. If the patient’s oxygen saturation target isn’t met with that starting flow, you can safely increase the delivery or switch to a higher-concentration device. High-flow options, like a non-rebreather mask, deliver much more oxygen but require a tighter seal, specific equipment, and closer monitoring, and they are reserved for more severe hypoxemia. A simple mask at higher flow is more invasive than a nasal cannula and is typically used when nasal cannula delivery isn’t sufficient. A very low nasal cannula flow may not be enough to relieve distress in many adults. So the common starting choice is a moderate flow through a nasal cannula, balancing comfort, safety, and the ability to adjust based on the patient’s response.
