A method and algorithm for remote monitoring of patients in asthma

Abstract

A method and algorithm for remote monitoring of patients in asthma is discussed. The method includes a comprehensive evaluation of the results of standardized questionnaire about disease symptoms, changes in the bronchodilator intake regimen and data of functional test of respiratory systems state. The proposed functional test is based on the assessment of the duration of tracheal sounds in the frequency band of 200–2000 Hz registered during forced expiratory maneuver. To record tracheal sounds a lapel microphone placed at the mouth outside the exhaled airflow is used. The algorithm of processing and analysis of diagnostic data is described. The developed diagnostic algorithm proved its effectiveness in the long-term monitoring of a group of healthy individuals and patients in asthma.
