Wheezometer® - The Only Point-of-Care Wheeze Detector
State-of-the-Art Wheeze Measuring Device
The Wheezometer® analyzes 30 seconds of breath sounds using advanced signal processing algorithms to detect, quantify and objectively document the presence of wheeze and its extent, the WheezeRATE™.
- The Wheezometer® is calibrated and validated as determined by consensus of a panel of experts who evaluated and scored many recordings for presence of wheeze.
- The Wheezometer® uses a cascade of 6 proprietary technologies to "defend" the signals against false detection of ambient noises as wheeze.
The Wheezometer® can be used by:
- Physicians: Pediatricians, GPs, internists, asthma/allergy specialists.
Nurses: Emergency, ICU/PICU/NICU, ward, asthma nurses, school nurses.
- Technicians and Paramedics: Respiratory therapists, EMS personnel, military medics, sports paramedics, occupational health officers.
- Patients and Caregivers: Under guidance of a healthcare professional.
WheezeRATE™: Proportion of the respiratory cycle duration occupied by wheezing - Tw/Ttot
The Wheezometer® design is based on ergonomic human-interfacing principles as dictated by functional and anatomical requirements in a state-of-the-art attractive form.
- Facilitates the correct anatomical placement of the device in contact with the trachea at the correct contact force.
- Provides stable contact with the skin surface for the duration of the test.
- Isolates the measuring head and sensor from vibrations and tremor of the hand holding the Wheezometer® .
| Wheezometer® provides a simple and intuitive user interface with clear Wz% readout, time and date of test, as well as specific icon indicators for unstable sensor contact and excessive ambient or patient noise. | |
| Infant Sensor™ (optional) is used for babies and toddlers who typically have a short neck. |
Wheezometer® uses:
- Obtain a “spot check” measurement of present wheeze activity, any time, any place, as often as needed without any patient effort.
- Measure WheezeRATE™ before and after administration
of a bronchodilator (“pre-post” test).
- Communicate status of homebound or remote patient to physician or healthcare professional.
