Desktop Spirometer
The first with ultrasound technology

Respiratory breath analysis

SpiroScout is the heart of all GANSHORN diagnostic systems. With the development of ultrasound flow measurement, GANSHORN opened new perspectives for spirometry and lung function testing. Based on simultaneous flow and molar mass determination, SpiroScout precisely measures all spirometric parameters and provides parallel information to the

SpiroScout spirometer is a complete lung function laboratory based on the GANSHORN ultrasound flow measurement method. It enables the exact determination of all spirometric parameters such as flow/volume, spirometry, lung volume, the one-second capacity FEV1 as well as static and dynamic lung function measurements including peak flow measurement. SpiroScout is the first and only spirometer in the world to measure flow and gas concentration simultaneously, enabling statements to be made about flow, volume and respiratory gas parameters with a single measurement. Depending on your needs, the modern ultrasound hardware will meet your clinical requirements.

Advantages of the GANSHORN SpiroScout

Highly accurate and precise

Calibration free

Compact and portable

Maintenance free

Reliable, ultra-fast and no warm-up time

Powerful, intuitive LFX software

Ultrasound technology

The heart of GANSHORN diagnostic systems
is its ultrasound sensor.

SpiroScout, PowerCube Body+ as well as the PowerCube Diffusion+ are based on GANSHORN ultrasound technology. So every measurement comes with precise and direct digital sound pulse transit-time flow determination of lung function. Every system, every session result, always the same accuracy and precision.

Measuring Options


PFT filter

The SpiroDef contains a filter fleece matching highest quality standards. It provides an effective mechanical barrier for aerosols. This reliably filters aerosols, bacteria and viruses which prevents not only contamination of the device, but also protects the ambient air. The SpiroDef allows a clean, economical workflow and impresses with an ergonomic shape. The extra compact filter saves not only space, but also minimizes the use of plastic and thus reduces waste. In order to attach the filter to the SpiroScout, a permanent breathing tube (as pictured below) is neccessary.



ScoutTube is the disposable mouthpiece of SpiroScout. It is easy to use and a hygienic solution, as you simply change it with every patient. Using the ScoutTube allows to measure without added resistance from a filter. It suits all ages from children to adults, at all levels of health. ScoutTubes are permeable to ultrasound waves. However, due to the small window size of the mesh and its arrangement, contamination of the device is unlikely.

Upgrades & additional options

Tidal breathing for children
This type of breath recording is used for newborns and infants where cooperation cannot be guaranteed.

SpiroScout TidalBreath

This form is used to assess the nasal cavity and respiratory function of the nose. It measures pressure and flow
during normal inhalation and exhalation through the nose.


Software platform

The LFX software is the GANSHORN user-friendly interface, developed with the physiologist in mind. It provides all tools necessary to perform every task done in the laboratory, while remaining easy to operate. Built on state-of-the-art Windows tools like .Net, C# and SQL database, the software is the future of modern respiratory diagnostics. LFX has built-in quality control monitoring based on ATS/ERS guidelines, which are accessible during and after the measurements are performed.

Capnovolumetry option

Capnovolumetry* is the analysis of the exhaled CO2 compared to the exhaled volume.
The CO2 concentration of exhaled air is plotted against the exhaled volume and thereby the anatomical airway dead space as well as the functional airway dead space can be determined. This method is independent of patient cooperation and therefore especially useful for monitoring respiratory diseases in both pediatric and geriatric patients.

Example graphs of capnovolumetry in patients with COPD of GOLD 2 and 3 severity, and in patients with and without emphysema. With increasing severity as well as the presence of emphysema, phase 3 becomes steeper and the difference in the slope to phase 2 becomes smaller, correspondingly the quotient s3/s2 becomes larger. 1
