The flow meter is an essential device used during oxygen administration as it precisely controls the flow rate of oxygen being delivered to a patient. It allows healthcare providers to set and measure the volume of oxygen that flows per minute, ensuring that patients receive the appropriate amount of oxygen necessary for their condition. Accurate flow rate control is crucial as it directly impacts the effectiveness of the therapy and the patient's overall wellbeing.

In the context of oxygen therapy, administering the right flow rate is vital to avoid complications such as oxygen toxicity or hypoxia. The flow meter provides vital feedback on the gas flow which helps in managing the patient's needs effectively.

Other potential functions listed in the choices, such as delivering medication, monitoring blood pressure, or adjusting temperature, fall outside the primary role of a flow meter in oxygen administration and are managed by different medical devices or instruments. Thus, the capability of the flow meter to control oxygen flow rates is what makes it a critical component in the administration of supplemental oxygen in various medical settings.
