Abstract
A respiratory mechanics measuring module includes a flow sensor, a differential-pressure sensor and a sampled-signal processing circuit which are connected in series. The module further includes a flow sensor reverse connection judging module and an alarm. The flow sensor reverse connection judging module judges the reverse connection of the flow sensor. The alarm gives an alarm signal indicating the flow sensor reverse connection to the main controller when the flow sensor reverse connection judging module judges that the flow sensor is reversedly connected.
