Reference standard design for flow calibration of mechanical ventilator and lung simulator calibrators

Special design flow calibrators are used for calibration of mechanical ventilators and lung simulators. It is necessary that these calibrators are connected to traceability chain via national standards. Mathematical models explaining the respiratory mechanics should be analyzed carefully before designing such a reference system for the purpose of calibration of flow calibrators. The purpose is to obtain a reference flow rate that shows a sinusoidal character. This paper explains the modeling studies and parameter considerations for design of the national reference standard at TUBITAK UME.
