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.

Abstract: Disclosed herein are devices, systems, and methods for updating alarm limits applied in monitoring one or more medical parameters of a subject. The devices, systems, and methods obtain a measurement of ambient pressure at a defined time point (‘t1’) and compare the measurement of ambient pressure at the defined time point (‘t1’) to a reference ambient pressure. If a difference between the measured ambient pressure values at t1 and the reference ambient pressure is at or above a predetermined threshold, the alarm limits are updated to correspond with the ambient pressure at t1 or a user is alerted to update the alarm limits.

Abstract: A connector connection indicator is mounted in a Luer male connector, or in a Luer female connector, to indicate proper mating of the two Luer connectors. The connection indicator may be or include a light source, a sound producing device (e.g., buzzer), a switch, a tactile connection indicator or an electronic chip. The electronic chip may be interposed between two conductive elements that are mounted in the Luer female connector. When the two Luer connectors are properly engaged, the electronic chip is powered via two electrical terminals. While the electronic chip is powered up it communicates with an external system via two electrical terminals. The external system interprets the communication with the electronic chip as an indication to proper engagement of the two Luer connectors. Some of the connection indicators may be mounted on a circuit board that is embedded in a void in the Luer male connector.
