Abstract: This paper describes design and development of a gas flow measurement system, which is particularly helpful for airflow measurement in anaesthesia ventilator. The system measured accurately, required range (0-70 l/m), of airflow for anaesthesia ventilator. Main advantages of developed technique are simplicity of design, dynamic stability and fast response time. Thermistor based hardware design associated with graphical approach has been developed successfully and incorporated in indigenous prototype of anaesthesia ventilator.
