What is a flowmeter used for in a healthcare setting?

A flowmeter is specifically designed to measure the rate of flow of gases or liquids, primarily in healthcare settings for monitoring oxygen delivery to patients. In the context of respiratory therapy, a flowmeter is used to indicate the flow rate of oxygen being delivered to a patient, ensuring that they receive the correct amount of oxygen based on their medical needs. This is crucial for patients with respiratory issues who require supplemental oxygen to ensure that the oxygen concentration remains within a therapeutic range.

The other options are related to different types of medical equipment. Measuring patient temperature is done with a thermometer, blood pressure is measured with a sphygmomanometer or an automated blood pressure monitor, and heart rate is monitored with a heart rate monitor or electrocardiogram. Each of these devices serves a distinct purpose in patient care, highlighting the specific role that flowmeters play in managing oxygen therapy.
