The WHolter® is used to continuously determine and provide a detailed report

  • WheezeRATE™, wheeze time over total time
  • Inspiratory and Expiratory WheezeRATE™
  • CoughCOUNT™, number of coughs per minute/hour
  • Respiratory Rate
  • I:E Ratio

WHolter® Listens to your patient when you can't...

Overnight or 24-hour WHolter® recording used to:

  • Document Nocturnal Asthma, assess its severity and provide a clear temporal pattern of overnight wheeze activity
  • Evaluate level of Asthma control and need for Step-up or Step-down of Asthma treatment
  • Evaluate Chronic Cough patients, symptom association (e.g. exposure) and response to treatment
  • Objectively document effect of occupational and environmental (e.g. fragrances) pollutants and allergens

The WHolter® overnight or 24 hours recorder is prescribed by a physician to assess symptoms, diagnose nocturnal asthma, chronic cough etc. Dispensing the unit, including patient education, correct application of the sensors in the right locations and activation of the recorder is done in a specialized clinic, e.g. PFT Lab, Sleep Lab, Holter (cardiac, hypertension, asthma/ allergy specialist) or at the physician’s office/clinic. At the end of 24 hours or 8 hours (if only nocturnal WHolter study is indicated) the patient returns the unit, the data is uploaded and sent for analysis and interpretation.

The WHolter® WheezeRATE™ overnight record of a 24 years old asthma patient. Note the early-morning wheeze that eventually woke the patient up to administer Albuterol. The overnight average WheezeRATE was 3.7% with 86 minutes (18.6% of the night) with WheezeRATE > 5%.

The WHolter® consists of a Data Logger recording unit with a 24 hours digital recording capacity to store continuous information from 2 PPG sensors, pneumogram belt and ambient microphone. The WHolter® is supplied with a Check-in/Check-out software that allows registering a patient when the device is dispensed, upload the recorded data to the computer and prepare the unit for the next patient. Data Analysis is performed by the PulmoTrack® software package sold separately, or as part of a PulmoTrack®-WHolter® . Use of ambient microphone for event recording.

The WHolter® is intended for performing ambulatory lung sounds and respiratory activity recording on those patients who may benefit from such a recording, including, but not limited to, those with complaints of shortness of breath, wheezing, cough, and when there is a need for performing continuous acoustic pulmonary function measurements.
