Oxygen Cells and Sensors
Search Not Found
In veterinary sciences, to measure the oxygen level inhaled or exhaled by the subject connected to the anesthesia machine, oxygen cells and sensors are used. It is important to know the amount of oxygen, as with a low oxygen supply, the subject may face difficulty in breathing. These cells are incorporated in the respiratory gas monitors (RGM’s). Oxygen sensors can be electrochemical or ultrasonic. Electrochemical sensors show the oxygen concentration through an electric signal. Ultrasonic oxygen cell is more economical and has a greater life shelf life as compared to the electrochemical sensor.
