Abstract

The disclosure provides a sensor system (10) for detecting bronchial tissular water content including at least a sensor (12) , a connector (14) , and a monitor (16). The sensor (12) generates a signal, which may be carried by the connector (14) to the monitor (16), which generates an output corresponding to the signal. The disclosure additionally provides a sensor (12) for detecting bronchial or tracheal tissular water content including at least a signal generator (44). The sensor (12) may also include at least a segment of a connector (14). The disclosure also provides a method of measuring bronchial or tracheal tissular water content by inserting a sensor (12) into an airway of a subject, such as a human, until it becomes lodged in a bronchus or the trachea, then measuring bronchial or tracheal tissular water content using the sensor (12).
