WHEEZE RATE - A New Paradigm in Asthma Management

CoughCOUNT™ - Objective Quantitativee Symptom Score

PulmoTrack-CC® Validated* CoughCOUNT™ Technology

Chronic cough is among the most frequent presenting symptoms in primary care, but its assessment is subjective and often inaccurate. The distribution and extent of cough can indicate:

  • Asthma
  • COPD or Chronic Bronchitis
  • Cystic Fibrosis
  • Gastroesophageal Reflux (GER)
  • Upper Airway Syndrome (Post Nasal Drip)
  • Objective Quantitative CoughCOUNT™ with the PulmoTrack-CC™ is essential in:
  • Evaluation of cough severity
  • Documenting nocturnal cough
  • Determination of response to treatment
  • Occupational medicine
  • Drug development and validation

* Validation of a Robust Cough Monitoring and Counting Application, ATS, 2009

Overnight or 24 hour cough monitoring provides minute-by-minute cough count with exact timing of each cough event (i.e. burst associated with a single inspiration) and component. This facilitates temporal association with:

  • Administration of treatment
  • Reflux events and meals
  • Wheeze
  • Change of body posture/activity
  • Exercise and exposure to cold
  • Exposure to noxious gases and ambient particles
  • Primary and secondary cigarette smoke

CoughCOUNT™: Number of coughs per unit time (minute or hour)

The PulmoTrack-CC™ is an optional patented* software application that can be used as part of the PulmoTrack® Wheeze real-time Acoustic Respiratory Monitor (ARM) or with the Wholter™ 8 - 24-hour recorder. For data acquisition, the PulmoTrack-CC™ uses the same sensors and hardware as the PulmoTrack® and the Wholter™. The application detects Cough Events which are either single or multiple Component Coughs as well as individual components. The User Interface is shown in Figures 1-2.

Fig. 1 (left): The PulmoTrack-CC™ Monitor interface shows minute-by-minute information on Tracheal and Chest Wall WheezeRATE™ (bars in top 2 panels) and CoughCOUNT™ per minute (3rd panel). The bottom panel shows the Respiratory Rate (blue) and I:E Ratio (gray). Time is in minutes.

Fig. 2a (top right: Clicking an individual minute bar opens a detail panel showing the timing of the Cough Events in long lines and secondary Components in shorter lines. Fig. 2b (bottom right): Shows the expanded time scale plot [in seconds] of one single-component and one two-component cough.


The PulmoTrack-CC™ is intended for detecting, counting, and recording coughs in patients when there is a need for objective documentation of the presence of cough in unrestricted environments.
