Abstract: A gas analyzing module includes a first connector, which includes a connection detection mechanism (CDM), and is connectable to a gas sampling line via a second connector. The gas analyzing module also includes a pump, a pressure sensor and a controller. The controller controls operation of the pump and receives a signal from the CDM. When the pump is on/active, the controller measures the CDM output signal, and if the CDM output signal indicates misconnection between the first connector and the second connector, the controller switches the pump off only if a pressure measured in the gas sampling line corroborates the CDM's misconnection indication, or, if the measured pressure refutes the CDM's misconnection indication, the controller maintains the pump's on state. The gas analyzing module may be a capnography module configured for capnography. Also provided is a gas analyzing system that includes the gas analyzing module and a gas analyzer.
