Pressure Transmitter for Medical Ventilators The medical ventilator plays a key role in the treatment of COVID-19 patients, especially for those hospitalized in ICU. Although there are many types of ventilators, their principle is generally the same. It helps move air or oxygen into the lungs and takes carbon oxide out, which helps patients' lung function when their bodies are fighting the infection. Inside the medical ventilators, there are types of sensors to monitor pressure, oxygen, flow, humidity, etc. Pressure sensor and transmitters for ventilators are needed for oxygen and air pressure control to ensure the ventilator work safely and smoothly. ACT Sensors manufactures pressure sensors and transmitters that may be used in medical ventilator systems to help control air or oxygen pressure.
