Mouthpiece and Airway Congestion Monitoring System

A congestion monitoring system comprising:

• a mouthpiece comprising a generally cylindrical, hollow form to channel a patient's breath, said mouthpiece including a flow restriction within the hollow form and a pair of air ports, wherein the first air port of the pair of air ports is located on the hollow form at a first side of the flow restriction, and the second air port of the pair of air ports is located on the hollow form at a second side of the flow restriction;
• a pair of air lines coupled to the pair of air ports;
• a sensor in communication with the pair of air lines;
• and
• a monitor device, wherein the sensor is adapted to convert a pressure signal from the pair of air lines into an electrical signal which is provided to the monitor device.

A method of providing information relating to pulmonary function comprising:

• providing a mouthpiece to a patient, said mouthpiece comprising a generally cylindrical, hollow form to channel a breath of the patient, said mouthpiece including a flow restriction within the hollow form and a pair of air ports, wherein the first air port of the pair of air ports is located on the hollow form at a first side of the flow restriction, and the second air port of the pair of air ports is located on the hollow form at a second side of the flow restriction;
• coupling the pair of air ports to a pair of air lines;
• receiving a pressure signal from the air lines at a sensor for a predetermined period of time;
• converting the pressure signal into an electrical signal representative of a flow rate of said patient;
• and
• transmitting the electrical signal to a monitor device.
