German Geratherm Diffustik


The Geratherm Respiratory Diffustik is the ideal measurement device for lung diffusion, offering reliable, reproducible results from an infrared fast gas analyser.

Diffustik has been developed as part of a modular system which can be expanded with the addition of further modules.


The Diffustik adapts to your needs and to those of your patients

Software options allow the expansion of the Diffustik with the inclusion of MIP (Maximum Inspiratory Pressure) and MEP (Maximum Expiratory Pressure)measurement. MIPs and MEPs give important information about respiratory drive, the respiratory muscles and the auxiliary respiratory muscles, this measurement allows investigation of neuromuscular disorders, such as amyotrophic lateral sclerosis (ALS).

A further software option allows measurement of airway resistance Rocc (Resistance by Occlusion)/Rint (Resistance by Interrupter). A test shown to be useful for less-collaborative patients (e.g. patients with advanced disease, geriatric patients or preschool children).

Further enhancement of the Diffustik can be made with the addition of Bronchial Provocation package. The use of different methacholine concentrations allows insight to the degree of bronchial hyperreactivity (especially asthma bronchiale) and helps in the determination of the correct treatment.

Patient comfort is always a priority for the designers at Geratherm Respiratory and the Diffustik is no exception designed around the height-adjustable measuring device, the device arm can be moved up and down easily and quickly by approximately 60 degrees and so offers the ability to perform examinations in either a sitting or standing position offering optimum patient comfort. The power of the Diffustik comes from the infrared fast gas analyser, enabling analysis of gas concentrations in real time during inspiration and expiration. The powerful BLUE CHERRY® software for pulmonary function diagnostic quickly calculates the results and displays user-friendly curve views along with the measurement values.
