The CORTEX CPET systems are intended for use in CPET, Spirometric, and Basal-/Resting Metabolic Rate Tests for the purpose to objectify the ventilatory, cardio-circulatory and metabolic capacity. With the following indications, they support the user in finding or confirming diagnoses, determining therapy programs and monitoring therapies.In a CPET test, a patient undergoes a period of defined physical stress (normally 10-20 minutes). Hereby data is measured about ventilation, gas exchange and heart rate. On basis of these measured data, further data is calculated and displayed, in order to depict the performance of the cardio-respiratory system.In a spirometry test, the patient performs defined breathing maneuvers (VC, FVC, MVV). Thereby measurement data of the respiratory strength and volume is collected and displayed, in order to show the mechanical capacity of the respiratory system.In a Basal-/Resting Metabolic Rate Test the patient performs a rest test (normally 15-20 minutes). Thereby measurement data of the gas exchange is collected and displayed, in order to estimate the Basal-/Resting Metabolic Rate.
An assembly of devices intended to noninvasively assess the cardiopulmonary response to exercise or measure of energy expenditure using indirect calorimetry. Breath by breath measurements of flow, oxygen (O2) uptake, and carbon dioxide (CO2) production are performed by O2 and CO2 analysers during exercise, along with the measurement of vital parameters. A mask, mouthpiece, or hood is attached to tubing and connected from the patient to the gas analysers while exercise is being performed using a particular device (e.g., an ergometer). The system typically monitors functions [e.g., provides continuous electrocardiogram (ECG)], provides control of the workload, and displays and prints results.
