Flowmeter Medical Oxygen

Oxygen is a vital element for breathing and metabolism. Some people need additional oxygen to improve their health and quality of life. For this purpose, there are special devices called medical oxygen flow meters.

Flowmeters are often used in hospitals and ambulances where a central gas supply (CGS) is available.

They are used to reduce pressure and regulate gas flow.

Flowmeter - What is it?

A medical oxygen flowmeter is a device that regulates the flow of oxygen from a central supply line. It is used to provide oxygen therapy to patients who require a specific amount of oxygen per minute. The oxygen is delivered to the patient via a tube and a mask or nasal cannula.

What types are there?

There are different types of flow meters for medical oxygen, which differ in their design, measuring principle and area of ​​application. Some examples are:

• Float flowmeters: These flowmeters have a transparent tube containing a float that moves up or down depending on the flow rate. The float can be a sphere, cylinder, or other shape. The tube is fitted with a scale that shows the flow in liters per minute (l/min). These flowmeters are easy to read and use, but they can become inaccurate if the tube becomes dirty or damaged.
• Orifice plate flowmeters: These flowmeters have an orifice plate that controls the flow of oxygen through a series of calibrated orifices. The orifices are labeled with different flow rates that can be selected by turning a handwheel. These flowmeters are robust and resistant to contamination, but they have only a limited number of adjustment levels.
• Digital flowmeters: These flowmeters have an electronic sensor that measures the flow of oxygen and displays it on a digital display. The flow rate can be adjusted using buttons or a rotary knob. These flowmeters are very accurate and can also display other parameters such as pressure, temperature or oxygen saturation. However, they require a power supply and are more expensive than other flowmeters.

The choice of the appropriate flowmeter for medical oxygen depends on various factors such as the available pressure, the required flow range, the patient type, the location and the budget. It is important that the flowmeter is regularly maintained and calibrated to ensure safe and effective oxygen therapy.
