Abstract
A respiration apparatus and a method for calibrating respiration parameters thereof are provided. A flow measuring reference component arranged behind the inspiratory valve in the ventilator is used as a flow measuring reference sensor for calibrating the flow sensor so that the flow rates of the gas through the flow measuring reference component and the flow sensor to be calibrated are identical or in a corresponding relation. Electrical parameters output from the flow sensor and the flow measuring reference component are respectively acquired and processed to obtain a relation curve of the gas flow rate and the electrical parameter of the flow sensor on the basis of the read gas flow rate and the electrical parameters of the flow sensor. The present invention enables automatic calibration for a flow sensor without using any measuring instrument.
