A congestion monitoring system includes a generally cylindrical, hollow form to channel a patient's breath, a flow restriction within the hollow form, and a pair of air ports. One of the air ports is located on the hollow form at a first side of the flow restriction, and the other air port is located on the hollow form at a second side of the flow restriction. The system also includes a coupling for connecting the pair of air ports to a pair of air lines, a sensor in communication with the air ports via the pair of air lines, and a monitor device. The monitor device converts a pressure signal from the air ports into a signal representative of a flow rate of the patient's breath through the hollow form.
