The Spirostik Blue is the latest generation of spirometers from Geratherm Respiratory. Thanks to the Bluetooth interface, it connects to a PC in seconds and allows flexible use, from the clinic to mobile use. The Spirostik Blue continues the hygiene concept of the disposable flow sensors and can optionally be used with a bacterial/viral filter for maximum safety.

Important documents

Disposable Flow Sensors

Replacing the flow sensor after each patient allows for a maximum standard of hygiene.

High mobility

The wireless Bluetooth interface connects to the PC in seconds.

Intuitive software

The user-friendly Blue Cherry software supports you with an automatic interpretation of findings.

Smart power management

The automatic standby and power-up of the device allow a long operation.

Spirometry - The basis of lung function

Spirometry is an essential tool for the screening, diagnosis and monitoring of restrictive and obstructive pulmonary diseases such as COPD or asthma, making it a valuable tool in all medical fields that deal with patients with dyspnoea. Especially against the background of the increasing number of COPD patients and post-Covid, early diagnosis through appropriate screening is becoming increasingly important.


Spirostik Blue – Maximum hygiene

Spirostik Blue follows the long-established hygiene concept of single-use flow sensors. The disposable flow sensor Blueflow is changed for each patient to ensure maximum patient safety and to avoid the risk of cross-contamination. The "snap-in handle" design allows the user to insert and remove the Blueflow without touching the sensor. The optional additional use of bacterial/viral filters also prevents contamination of the examination room. The Spirostik Blue thus offers the highest possible level of safety with regard to the Covid-19 pandemic.


Maximum mobility

Battery operation together with wireless (Bluetooth) data transmission and the power of the BLUE CHERRY® pulmonary function diagnostic platform make the Spirostik Blue an excellent choice in any environment: thanks to the freedom of movement, the tests can be easily performed in multiple examination rooms or patient rooms using a laptop or tablet . Once the Spirostik Blue and the PC are paired via Bluetooth, the device connects automatically within seconds and delivers stable and reliable results directly into the BLUE CHERRY® diagnostic platform.

Accessories for the Spirostik Blue

Blueflow Disposable Set

Set of disposable low resistance flow sensor and comfortable nose clip. Continuous checks in production ensure reliable measurement results.


The optional Safestik automatically establishes the connection between the PC and Spirostik Blue, so that no Bluetooth is required on the PC. The secured data connection ensures maximum data security.


The Ambistik system extension continuously measures the temperature, air pressure and humidity of the environment. The Ambistik thus offers fully automatic BTPS correction in real time for precise measurement results.

Questions and answers

The Spirostik Blue can be used to measure slow vital capacity (SVC), forced vital capacity (FVC, flow/volume loop) and maximum voluntary ventilation (MVV).

Yes, a (semi-)automatic interpretation according to ATS/ERS 2005 is included. In addition, a proprietary interpretation graphic allows a quick visual evaluation of the results.

Yes, the acceptability and reproducibility of the examinations are automatically evaluated according to ATS/ERS 2019 or alternatively ATS/ERS 2005..

Reference values ​​from GLI 2012, ECCS 1993, NHANES III, Zapletal and many more are available. These can be displayed as absolute reference values, LLN, ULN, but also in relation to the measured values ​​as % reference and Z score.

Yes, the data is stored on a central SQL database. This means that the data can be accessed from several computers. The Spirostik can be used together with other devices from Geratherm Respiratory in a network via the common BLUE CHERRY® software platform.
