What is the purpose of the flowmeter in nitrous oxide administration?

The flowmeter serves a crucial role in the administration of nitrous oxide by providing a clear indication of the flow rate of gases being delivered to the patient. Accurate flow regulation is essential in ensuring that the patient receives the appropriate concentration of nitrous oxide mixed with oxygen, delivering an effective sedative effect while maintaining safety. This device allows healthcare providers to monitor and adjust the flow according to the patient's specific needs, creating an optimal balance for sedation. By indicating the precise rate at which the gases are flowing, the flowmeter enhances patient safety and comfort during dental procedures.
