Innocor + PADSYergo
Complete cardiovascular diagnostics
PADSY-Ergospiro combines expertise in 12-channel ECG stress testing with expertise in pulmonary function testing. An innovative and efficient 12-channel stress ECG system, PADSY-Ergo is connected to the ergo spirometry system via an intelligent link, thus allowing highly precise cardiovascular analyses. The stress ECG and stress spirometry are recorded synchronously, identifying cardiac, pulmonary and vascular function in just a single measurement. Patient data, heart rate and stress testing data are transferred by PADSY-Ergo to the respective ergo spirometry system. This multifunctional measurement station expands the possibilities of cardiovascular diagnostics, thus providing key information for patient-appropriate diagnosis and therapy. PADSY-Ergospiro is compatible with the most important ergo spirometry systems and, thanks to its flexibility, is the perfect solution for existing and future ergo spirometry systems.

Revolution in Ergospirometry measurement
Combining PADSY-Ergo with the innovative Innocor ergo spirometry system increases reliability when it comes to assessing cardiovascular examinations. Innocor® utilises a proprietary gas analyser technology for measuring nitrous oxide (N2O, blood soluble), sulphur hexafluoride (SF6, insoluble) and CO2 continuously and simultaneously. The advanced analyser is a photo-acoustic infra-red type which combines a fast response with unsurpassed sensitivity and accuracy and inherent stability. No tedious calibrations are required – all you need is a yearly calibration check. This technology replaces a medical mass spectrometer for inert gas analysis and offers superior performance. The oxygen sensor uses laser diode absorption spectroscopy, meaning no limited life parts. A Nafion sampling tube ensures optimal humidity removal. Use of these innovative technologies produces valid breath-by-breath measurements, and allowing reliable determination of the anaerobic threshold.
Cardiac Output for hemodynamic measurements
Innocor® gives the complete metabolic and hemodynamic profile comprising a conventional CardioPulmonary Exercise Test (CPET) together with non-invasive measurement of Cardiac Output. This unique combination enables the possibility to distinguish between ventilatory, central circulatory or peripheral causes of exercise intolerance. By using inert gas rebreathing for hemodynamic measurements the hazards and costs of using PA-catheters are eliminated and inaccuracies of other methods avoided.
Inert gas rebreathing method
During a rebreathing test the subject rebreathes an oxygen enriched mixture containing very small amounts of two physiologically inert gases – one blood soluble and one insoluble component – from a closed rebreathing system. The test lasts about 5 breaths or 15 seconds. During this time the blood soluble gas is dissolved in the blood perfusing the ventilated parts of the lungs. Innocor® measures the concentration curve of the blood soluble gas and calculates the wash-out rate, which is proportional to the Cardiac Output. In patients with a significant intra-pulmonary shunt, the shunt flow is calculated by using the well proven Fick principle for oxygen. The blood insoluble gas is measured to determine the lung volume and to account for other factors that affect the distribution of the blood soluble gas.
