What Geratherm Respiratory does
Geratherm Respiratory GmbH is a privately held German medical device company headquartered in Bad Kissingen, Germany, with production carried out exclusively in Germany. The company develops, manufactures, and distributes diagnostic equipment across three respiratory and cardiopulmonary categories: Spirometry (Spirostik Blueflow), Pulmonary Function Testing (PFTstik, Bodystik with optional Add-on CO Diffusion), and Cardiopulmonary Exercise Testing (Ergostik, Ergostik Blueflow, plus Ambistik BTPS environmental modules). At the core of the portfolio is the proprietary BLUE CHERRY® diagnostic software platform, a Microsoft SQL Server-based application that unifies measurement, review, interpretation, and reporting across all devices and scales from single workstations to enterprise hospital network deployments via HL7 and GDT interfaces. Differentiated hardware features include the sub-20g Ergoflow sensor with no moving parts, disposable Blueflow flow sensors for infection control, calibration-free DLCO technology, and automatic ATS/ERS quality controls.
The business model combines hardware sales of diagnostic devices with associated software licensing (BLUE CHERRY) and recurring revenue from disposable flow sensors. Distribution is exclusively indirect: more than 120 sales partners and distributors serve hospitals, clinics, pulmonary function laboratories, and sports/perioperative medicine facilities across all continents, supplemented by participation in flagship industry events such as the ERS Congress (2026 edition scheduled September 5-9) and a dedicated distributor portal. The company is led by CEO PD Dr. med. Oliver Gödje and COO/founder Florian Dassel, with Thomas Bindig as VP Sales, and operates under ISO 13485:2021 certification (valid 2025-2028) and CE marking per EU 2017/745 MDR through Notified Body SLG Prüf- und Zertifizierungs GmbH (0494). No public listings, external funding rounds, or acquisitions are disclosed in available source material.
