Medical Gases and Oxygen Flow Rate 2025 – 400 Free Practice Questions to Pass the Exam

The flowmeter is the correct choice for setting and monitoring oxygen flow rates because it is specifically designed to measure the rate at which oxygen is delivered to a patient. This device allows healthcare providers to adjust the flow to meet the individual needs of patients requiring supplemental oxygen. Flowmeters can provide both visual and tactile feedback on the rate of flow, often displayed in liters per minute, which helps clinicians ensure proper dosage during treatment.

Other devices listed serve different purposes: an oximeter measures blood oxygen saturation levels and is used to assess how well oxygen is being distributed in the bloodstream. A pressure gauge indicates the pressure of the oxygen supply in the cylinder but does not measure flow rates. Lastly, a humidifier is used to add moisture to dry oxygen but is not involved in monitoring or setting flow rates. Understanding the specific functions of these devices highlights why the flowmeter is essential for managing oxygen therapy effectively.
