1. Apparatus comprising:
- a sensor configured to sense a breathing-related sound of a subject selected from the group consisting of;
coughing of a subject and wheezing of the subject, and to generate a signal responsively to the selected breathing-related sound;
a breathing sensor configured to sense breathing of the subject and generate a breathing signal responsively thereto; and
a control unit configured to;
receive the signal generated responsively to the selected breathing-related sound;
receive the breathing signal;
in response to the received signals, determine a correlation between timing of a breathing cycle of the subject and timing of the breathing-related sound; and
in response thereto, monitor a condition of the subject selected from the group consisting of;
asthma, chronic obstructive pulmonary disease (COPD), congestive heart failure (CHF), cystic fibrosis (CF), and epilepsy.

Abstract
A method is provided for predicting an onset of a clinical episode, the method including sensing breathing of a subject, determining at least one breathing pattern of the subject responsively to the sensed breathing, comparing the breathing pattern with a baseline breathing pattern, and predicting the onset of the episode at least in part responsively to the comparison. Other embodiments are also described.

6. A method comprising:
-
sensing a breathing-related sound of a subject selected from the group consisting of;
coughing of a subject and wheezing of the subject;sensing breathing of the subject with a sensor; determining a correlation between timing of a breathing cycle of the subject and timing of the breathing-related sound; and in response thereto, monitoring a condition of the subject selected from the group consisting of;
asthma, chronic obstructive pulmonary disease (COPD), congestive heart failure (CHF), cystic fibrosis (CF), and epilepsy,the method being performed using apparatus including; a sensor configured to sense the selected breathing-related sound and to generate a signal responsively to the selected breathing-related sound; a breathing sensor configured to sense breathing of the subject and generate a breathing signal responsively thereto; and a control unit configured to; receive the signal generated responsively to the selected breathing-related sound; receive the breathing signal; in response to the received signals, determine the correlation between timing of the breathing cycle of the subject and timing of the breathing-related sound; and in response thereto, monitor the selected condition of the subject. - View Dependent Claims (7, 8, 9, 10, 11)
