What is defined as an oxygen flowmeter?

  1. A device that indicates oxygen pressure

  2. A device that controls the rate of oxygen flow

  3. A device that stores oxygen

  4. A device that transforms oxygen for inhalation

The correct answer is: A device that controls the rate of oxygen flow

A flowmeter is specifically designed to control and measure the rate at which oxygen is delivered to a patient. It functions by allowing the healthcare provider to set a specific flow rate, typically in liters per minute, which is crucial in ensuring that the patient receives the appropriate amount of oxygen for their medical needs. While the other options mention aspects related to oxygen delivery systems, they do not accurately describe the function of a flowmeter. For example, devices that indicate oxygen pressure are designed to provide readings of the pressure within an oxygen tank, but do not control flow. Similarly, storage devices are meant for holding the oxygen, and transformers refer to devices that convert oxygen for breathing but are not involved in regulating its flow. Hence, the role of a flowmeter is to facilitate precise control over oxygen delivery, which is integral in emergency medical scenarios.
