• 1-6 L/min

• 2-15 L/min

• 10-20 L/min

What is the primary function of the one-way valves in a Non-Rebreather Mask?

• To allow room air to enter the mask during inhalation.

• To prevent carbon dioxide from escaping the mask.

• To ensure a high fraction of inspired oxygen and prevent room air from entering during inhalation.

• To humidify the oxygen delivered to the patient.

What is a key benefit of using a High Flow Nasal Cannula?

• It is suitable for patients requiring less than 10 liters per minute of oxygen.

• It does not require specialized equipment for operation.

• It provides humidified and heated oxygen, which enhances patient comfort.

• It is the ideal choice for immediate, very high oxygen delivery in severe respiratory distress.
