Oxygen therapy
Oxygen therapy ( 22 Questions)
(Select all that apply): A nurse is educating a group of patients about different oxygen delivery devices. Which of the following are examples of low-flow oxygen delivery systems?
Nasal cannula is a low-flow oxygen delivery system because the oxygen flow rate is relatively low and the delivered oxygen is mixed with room air before reaching the patient's lungs.
The simple face mask is a low-flow oxygen delivery system. It delivers oxygen at a fixed flow rate and allows room air to mix with the delivered oxygen.
Venturi mask is not a low-flow oxygen delivery system. It is a high-flow system that provides a specific and precise FiO2, making it suitable for patients with chronic respiratory conditions.
The non-rebreather mask is not a low-flow oxygen delivery system. It is a high-flow system that is used when the patient requires a high FiO2, close to 100%, to ensure adequate oxygenation.
Choice A rationale:
Nasal cannula is a low-flow oxygen delivery system because the oxygen flow rate is relatively low and the delivered oxygen is mixed with room air before reaching the patient's lungs.
Choice B rationale:
The simple face mask is a low-flow oxygen delivery system. It delivers oxygen at a fixed flow rate and allows room air to mix with the delivered oxygen.
Choice C rationale:
Venturi mask is not a low-flow oxygen delivery system. It is a high-flow system that provides a specific and precise FiO2, making it suitable for patients with chronic respiratory conditions.
Choice D rationale:
The non-rebreather mask is not a low-flow oxygen delivery system. It is a high-flow system that is used when the patient requires a high FiO2, close to 100%, to ensure adequate oxygenation.
Choice E rationale:
Aerosol mask is a low-flow oxygen delivery system that delivers oxygen mixed with aerosolized medication. The flow rate is relatively low compared to high-flow systems.
