An oxygen flow meter is a medical device used to control and measure the flow of oxygen from an oxygen source (such as an oxygen cylinder or oxygen concentrator) to the patient. It is an essential component in oxygen therapy, allowing healthcare providers to adjust the flow rate of oxygen delivered to meet the patient's respiratory needs.
