Introduction to Ventilators and Ventilation Rate Measurements

Abstract: This application note provides an introduction to ventilators and their basic functions. It discusses how ventilation rates are measured and provides the formula for determining if the tidal volume of gas exchange is sufficient for the patient. The system subfunctions addressed include air-oxygen mixture sensing, air-oxygen mixture control, inspiration control, the communication interface with the technician/doctor, and the alarm system.
