When preparing to apply oxygen via nasal cannula to a patient for low saturations, what is the order of connecting the components from the oxygen source in the wall to the patient?
Explanation
Answer: B-Oxygen is connected from the wall source to the patient via the flow meter, connector, humidifier, and tubing, in that order. The flow meter is connected to the oxygen source, and controls how much oxygen is delivered to the patient. This is connected to a humidifier, which adds moisture to the oxygen to prevent drying. The oxygen is then delivered to the patient through the tubing.
