Respiratory sound analysis for lung health assessment

A method for measuring and analyzing respiratory sounds of a patient's lungs, the method comprising:

• sensing at least one of respiratory sounds or chest wall movement, using at least one sensor coupled with a high frequency chest wall oscillation (HFCWO) vest, the at least one sensor including a transmitter voice coil actuator and a receiver voice coil actuator, and sensing the at least one of the respiratory sounds or the chest wall movement including transmitting a signal from the transmitter voice coil actuator on a first side of the HFCWO vest, and receiving the signal with the receiver voice coil actuator on a second side of the HFCWO vest;
• converting sensed data from the patient's lungs to electronic data;
• processing the electronic data to provide lung function assessment data by measuring a phase shift between the transmitted signal and the received signal;
• providing the lung function assessment data to a user;
• determining whether the patient's breathing is at or above a predetermined threshold clarity based on the lung function assessment data;
• and
• automatically stopping a percussive treatment when the patient's breathing reaches the predetermined threshold clarity or a prescribed treatment time elapses, whichever occurs first.
