Documentation for cannula should include which parameter?

• A. Humidification level
• B. Oxygen source
• C. Device type
• D. Flow rate (L/min)

Answer: (D)

Flow rate is the key quantity to document because the amount of oxygen delivered with a nasal cannula isn’t fixed by the device itself. The FiO2 a patient receives depends on how much gas is being delivered (the flow rate in liters per minute) and the patient’s breathing pattern. Recording the flow rate communicates the actual dose being given and allows safe titration and future adjustments. The other items don’t specify the delivered dose. The device type tells you what kind of interface is used but not how much oxygen reaches the patient. The oxygen source matters for equipment management, but it doesn’t define the specific dose. Humidification level can be used in some notes, but it isn’t the standard parameter that defines the cannula’s delivered oxygen.
