Function: The primary function of a medical oxygen flowmeter is to control and regulate the flow rate of medical oxygen. It allows healthcare providers to adjust and set the flow rate according to the patient’s needs.

Flow Rate Control: Flowmeters feature a control knob or mechanism that healthcare professionals can adjust to select the desired flow rate. Flow rates are typically measured in liters per minute (LPM).

Color Coding: Oxygen flowmeters often use specific color codes to distinguish them from flowmeters used for other gases. For instance, oxygen flowmeters are typically green or have a green label.

Pressure Compensation: Many oxygen flowmeters are designed to operate accurately across a range of inlet pressures. This ensures consistent flow even when the source pressure varies.

Readout: Flowmeters usually have a visual readout, often in the form of a rotating float or a ball that moves within a calibrated tube to indicate the flow rate.

Outlet Connection: The flowmeter connects to the oxygen source, and the outlet is typically compatible with standard medical tubing or connectors.

Flow Calibration: Flowmeters are calibrated to deliver a specific flow rate accurately. Calibration may be required periodically to maintain accuracy.

Portable and Stationary Units: Oxygen flowmeters come in both portable and stationary versions. Portable flowmeters are used for mobile oxygen therapy, while stationary units are installed in healthcare facilities.

Compatibility: Flowmeters should be compatible with the medical gas source being used, such as oxygen concentrators, oxygen cylinders, or central pipeline systems.

Accuracy and Precision: Flowmeters are designed to be accurate and precise to ensure that patients receive the prescribed oxygen flow rate, especially in critical medical situations.

Safety Features: Some flowmeters incorporate safety features, such as built-in pressure relief valves, to prevent over-pressurization.

Cleaning and Maintenance: Regular cleaning and maintenance are essential to ensure the flowmeter’s proper functioning and hygiene.
