What is the recommended oxygen flow rate for patients receiving the SNORES bundle?

• A. 2 LPM
• B. 6 LPM
• C. 8 LPM
• D. 4 LPM

Answer: (D)

Oxygen delivery with a nasal cannula is set to provide enough support without causing discomfort or wasting oxygen. Four liters per minute is used in the SNORES bundle because it delivers a modest FiO2—usually enough to bring oxygen saturation toward target levels for many adults—while staying comfortable and easy to manage. A lower flow, like two liters per minute, often isn’t enough to raise sats reliably, whereas higher flows (six to eight liters per minute) deliver more oxygen but can cause nasal dryness and discomfort and aren’t needed unless the patient’s oxygen needs are greater. So four liters per minute strikes a practical balance for baseline oxygenation in the SNORES bundle. If a patient still has low oxygen saturation on that flow, escalation follows the protocol.
