• Study success will be declared if one of the following is met: A correlation of at least 0.25 (R2=0.25) will be found between WR and FEV1 measurements; A correlation of at least 0.7 will be found between clinical parameter and WZ measurements. [ Time Frame: 6 months ] [ Designated as safety issue: No ]
  

• Evaluation of the safety of using the PulmoTrack® 2010 with WIM-PC™ Technologies for wheeze detection. Safety will be established by lack of adverse events. Since this is a Non Significant Risk (NSR) device serious adverse events are not expected [ Time Frame: 1 hour ] [ Designated as safety issue: Yes ]
  

Asthma is defined by the National Asthma Education and Prevention Program (NAEPP) guideline as a 'Chronic inflammatory disorder of the airways in which many cells and cellular elements play a role. The asthma guideline states that inflammation causes recurrent episodes of wheezing, breathlessness and chest tightness that are associated with widespread but variable airflow obstruction. Wheeze quantification by lung sounds analysis methods is objective, non invasive and has been shown to correlate with clinical status in asthma and bronchiolitis. The recording procedure is simple, requiring only the attachment of 4 ECG-size sensors to the chest wall. A 30-second recording is often adequate to obtain good quality data, where wheezes are detected and counted with high degree of accuracy.

Karmel Sonix Ltd has developed the PulmoTrack® 2010 with WIM-PC™ Technologies device, indicated for acoustic pulmonary function measurement that quantifies the presence of wheezing. This study was designed in order to evaluate the efficacy and safety of using the PulmoTrack® 2010 with WIM-PC™ Technologies device for wheeze detection during dynamic bronchial situations in asthmatic adults.
