What is the most common rate of oxygen administration in an emergency situation?

In emergency situations, the most common rate of oxygen administration is often set at around 2 liters per minute. This rate is generally sufficient to provide supplemental oxygen while minimizing the risk of complications associated with higher flow rates. At 2L/min, the aim is to achieve a target oxygen saturation that supports the patient's needs without overwhelming the respiratory system.

In many emergency protocols, this flow rate is typically used for patients who are in a stable condition or who require a little assistance with their oxygen levels. It strikes a balance between delivering adequate oxygen and avoiding potential issues related to oxygen toxicity or retention, particularly in patients with chronic obstructive pulmonary disease (COPD).

Higher flow rates, such as 5L/min or greater, may be reserved for more acute situations where patients exhibit signs of significant oxygen deprivation or have critical signs requiring rapid intervention. However, in standard emergency care, starting at a lower flow is common practice to assess the patient's response and adjust as necessary.
