What is the recommended oxygen flow rate for managing breathing deterioration?

In managing breathing deterioration, the recommended oxygen flow rate is crucial to ensure adequate oxygenation without causing harm, particularly in conditions such as chronic obstructive pulmonary disease (COPD) or asthma. A flow rate of 15 liters per minute represents an aggressive approach to delivering high-flow oxygen, which can be necessary in acute situations where a patient's respiratory status is severely compromised.

At this rate, the oxygen delivered can effectively improve oxygen saturation levels and support the patient's breathing. It is important to monitor the patient closely, as such high flow rates may not be appropriate for all patients, especially those who may be at risk for hypercapnia.

The other options, while delivering oxygen as well, may not provide the same level of swift support needed in cases of critical deterioration. Lower rates like 5L or 10L may not suffice in emergencies where immediate improvement in oxygenation is necessary.
