A Ventilator is a medical device normally used in hospitals and medical organization to help patient breath and recover from lung diseases. Function of ventilator: Bring pure oxygen into the lungs. Remove carbon dioxide out of the body. (Carbon dioxide is a waste gas that can be toxic.) Help people have an easy breathe. Offer breath assistance for people who have lost all ability to breathe on their own.

Ventilators could be used in below 2 situations: 1. During surgery if you’re under anesthesia or under operation (ICU) needs assistance in breathing. If you have general anesthesia during surgery, you'll likely be connected to a ventilator. It is used to induce anesthesia can disrupt normal breathing. A ventilator helps you continue breathing during surgery. 2. If your lung function is impaired by a disease or condition. You will need a ventilator if your breathing is impaired by a disease or condition. It is very hard for you to breathe on your own. For example, you may feel short of breath...

3. How does a ventilator work? Ventilators bring fresh air or oxygen into your lung then take the wasted gas such as carbon dioxide out of your lung. Normally a ventilator uses positive pressure to blow air or a mixture of gases (like oxygen and air) into the lungs. Patients usually exhale( breath out) the air on their own, but sometimes the ventilator will exhale the air out too. Generally a ventilator working mode is set to breathe a set number of times a minutes to trigger the device to blow air into your lungs. But if patients fail to trigger the device within a certain amount of time, the...

into your mouth your throat During ventilator work process, we need an oxygen sensor to measure oxygen concentration to ensure the oxygen concentration is in stable level and oxygen is enough to help patient breath. If the oxygen level is lower than the set value, the device will alarm then need to change oxygen resource to ensure the smooth working of ventilator.

5. How does ventilator measure oxygen concentration？ Technical principle Principle Description Differential Pressure Sensor In a bypass configuration, the differential pressure sensor is placed over a pressure drop element/ orifice. An air flow in the main pass will create a differential pressure over the pressure drop element, which is proportional to the air flow. Low Pressure Drop Flow Meter sensor A hot wire mass airflow sensor determines the mass of air flowing into the engine’s air intake system. The theory of operation of the hot wire mass airflow sensor is similar to that of the hot wire anemometer (which determines air velocity) The ...
