What is the purpose of a flow meter in medical gas systems?

The purpose of a flow meter in medical gas systems is to measure and regulate the flow of gas being delivered to a patient or system. Flow meters provide critical information about how much gas is being dispensed, allowing healthcare professionals to administer the correct dosage required for patient care. This regulation is essential in ensuring that the patient receives the appropriate amount of gas, whether it be oxygen, nitrous oxide, or another gas necessary for treatment.

By accurately controlling the flow, flow meters help prevent complications that could arise from administering too much or too little gas. This is particularly vital in medical environments where patients often have varying and specific needs based on their clinical conditions. The design of flow meters allows for real-time monitoring, which enhances patient safety and treatment effectiveness.

The other options do not address the primary function of a flow meter. Amplifying sound, storing gas, and increasing pressure relate to different aspects of gas management and delivery, but they are not the main purpose of a flow meter in the context of medical gas systems.
