History of Innovation

iSonea has a long history as an innovator in the development of Acoustic Respiratory Monitoring (ARM™) technology that encourages users to better monitor and manage asthma, COPD and other chronic breathing conditions. Some of these technologies include PulmoTrack®, Wheezometer® and WHolter®.


PulmoTrack® is used in a doctor’s office to precisely measure wheeze rate. It uses two acoustic sensors attached to the user’s skin at the trachea and chest — a pneumograph belt sensor for documenting breathing activity and an ambient microphone to filter environmental noises.

Wheeze detection is carried out by patented software using advanced algorithms that apply strict criteria to determine the presence of wheezing.

It can be used for:

  • Bronchodilatation Test to measurement of response to treatment.
  • Bronchoprovocation Test, particularly for infants or other non-cooperative patients.
  • Performance of physical examination in a pulmonary function testing environment to identify and quantify the presence of wheezing.









The Wheezometer® was the first device from iSonea to make asthma monitoring portable and non-intrusive. Placed at the base of the throat, the Wheezometer® can be used for a “spot check” wheeze measurement at home or in a remote location, and requires no effort on the part of the patient to use.

Its design facilitates the correct placement in contact with the trachea and provides stable contact with the skin for the duration of use.











WHolter® is the first ambulatory 24-hour recorder to provide objective and quantitative information about wheezing and coughing for patients with nocturnal asthma, COPD, occupational asthma, chronic cough or allergies. WHolter® is prescribed by a physician.
