1. A method for analyzing respiration of a subject, the method comprising:
- using a non-contact microphone, generating a raw signal indicative of airflow sounds of the respiration;
analyzing the raw signal to determine a first set of one or more parameters of the respiration; and
applying an algorithm to the first set of parameters to derive a second set of one or more estimated parameters of the respiration that are not generally directly measurable in the raw signal.

Abstract
A method is provided for analyzing respiration of a subject (20). Using a non-contact microphone (22), a raw signal indicative of air-flow sounds of the respiration is generated. The raw signal is analyzed to determine a first set of one or more parameters of the respiration. An algorithm is applied to the first set of one or more parameters of the respiration. An algorithm is applied to the first set of parameters to derive a second set of one or more estimated parameters of the respiration that are not generally directly measurable in the raw signal. Other embodiments are also described.
