Smart sensor technologies are now commonly used to monitor and control mechanisms in a wide range of applications, especially in the ever-growing medical field. These sensors can boost the competence of medical devices such as respiratory gas monitors (RGM). Moreover, a medical oxygen sensor also helps to precisely measure the gas flow in anesthesia machines and ventilators, and calculate accurate oxygen concentration, etc.

Why Does an RGM Need an Oxygen Sensor?

The respiratory gas monitor system needs an accurate and efficient medical oxygen sensor to make all these functions work. This sensor is also known as a flow sensor because it measures the flow of oxygen and its concentration or partial pressure of oxygen in the breathing gas mixture. Along with this, there are many more benefits the oxygen monitor sensor provides to an RGM machine, such as:

1. Circulating Breathable Air

The medical oxygen sensor is utilized in RGM equipment, such as medical ventilators, which pump breathable air into and out of the patient’s lungs. Its purpose is to provide oxygen to those who are unable to breathe on their own or those who are having trouble breathing because of an illness.

The medical oxygen sensor determines the gas flow by comparing the ultrasonic velocities upstream and downstream. It has pressure sensors, which are critical components in ventilators that provide breathing. A mixture of oxygen and air is supplied into the patient’s lungs through a tube inserted into the patient’s mouth, nose, or windpipe.

2. Gas Mixture Measurement during Ventilation

The breathing gas mixture must be precisely measured during ventilation, which is done smoothly with the help of oxygen sensors in RGM. Individual gasses are measured by the flow sensors installed inside it before aspiration so that the gas mixture is supplied as per the prescription.

These devices can also measure accurate oxygen supply during the procedure by taking readings every second. Manufacturers of ventilators frequently use electro-galvanic medical oxygen sensors, which can measure the air that has been compressed in oxygen tanks up to 100% for effective oxygen control.

3. Control and Detect the Calculated Oxygen

Oxygen plays a vital role in an individual’s anatomical functionality; thus, measuring and controlling oxygen concentration during breathing is absolutely mandatory. In this case, medical oxygen sensors are used to monitor and control the patient’s estimated oxygen needs.

This information is crucial so the doctor can decide the amount of oxygen a patient needs. Depending on the circumstances, the patient may require 100% oxygen or considerably less.

4. Highly Accurate Measurements of the Oxygen Content of the Breathing Gas

As it is exposed to atmospheric gas, the chemistry inside the sensor produces an electrical output (voltage or amperage) proportional to the gas level. Every form of anesthesia equipment, including continuous-flow anesthesia machines, uses a medical oxygen sensor. It is intended to give oxygen to the patient at a safe pressure and flow with an exact and continuous supply of medicinal gasses (such as oxygen O2 and nitrous oxide N2) mixed with an accurate concentration of anesthetic vapor.

To account for pressure changes and drift, the medical oxygen sensor compares the sample gas mixture with pure oxygen and nitrogen gasses. This eliminates the uncertainty associated with using bottled calibration gas mixtures.
