What is the recommended oxygen delivery method for a patient exhibiting severe respiratory distress?

• A. Nasal cannula
• B. Venturi mask
• C. Non-rebreather mask
• D. Simple face mask

Answer: (C)

In cases of severe respiratory distress, the non-rebreather mask is the recommended oxygen delivery method. This device is designed to provide a high concentration of oxygen, which is crucial for patients struggling to breathe adequately. The non-rebreather mask can deliver up to 90-100% oxygen, significantly increasing the level of oxygen available to the patient. By using a one-way valve and a reservoir bag, the mask prevents the re-inhalation of exhaled carbon dioxide and allows the patient to receive oxygen continuously. This is particularly important for patients in severe respiratory distress, as they may not only require high-flow supplemental oxygen to correct hypoxemia but also need immediate intervention to improve their oxygenation status. Other oxygen delivery methods, such as a nasal cannula or simple face mask, typically provide lower concentrations of oxygen and may not suffice for patients in critical respiratory distress. Although a Venturi mask can deliver a precise concentration of oxygen, it is better suited for patients needing less supplemental oxygen or those with specific conditions like COPD, rather than emergency situations of severe respiratory distress.
