Overview

The VO2maxFinder ergospirometer by MES Sp. z o.o. is a stationary, modular medical device designed for comprehensive cardiopulmonary exercise testing (CPET) in laboratory settings. It features advanced technology for breath-by-breath respiratory and circulatory system analysis, meeting and exceeding American Thoracic Society (ATS) and European Respiratory Society (ERS) accuracy standards.

Key Components and Technology

• MES DV40 Pneumotachograph Head: Patented low-resistance, lightweight headpiece with no moving parts, minimal dead space (38 ml or 20 ml), and insensitivity to humidity, ensuring patient comfort and high measurement accuracy.
• Digital Flow Converter: Integrated directly on the pneumotachograph head, transmitting digital flow signals via cable to the main unit, eliminating air hoses and reducing signal distortion.
• Gas Analyzers: Fast-response oxygen (laser-based) and carbon dioxide (NDIR infrared) sensors with response times under 100 ms and long lifetimes (>5 years).

Applications

The device is suitable for cardiology, pulmonology, exercise physiology, sports medicine, cardiac rehabilitation, occupational medicine, intensive care, nutrition assessment, and environmental medicine. It supports testing with various exercise equipment such as cycle ergometers and treadmills.

Measurement Capabilities

• Breath-by-breath analysis of respiratory volume, flow rate, O2 and CO2 concentrations, and 12-lead ECG signals.
• Continuous recording and storage of full test data with the ability to review individual exhalations.
• Non-invasive cardiac output estimation using the Wassermann Algorithm.
• Measurement of energy expenditure and substrate oxidation.
• Automatic or manual determination of aerobic, anaerobic, and respiratory compensation point (RCP) thresholds.

Modular Extensions

• Full spirometry tests compliant with ERS/ATS standards, including slow spirometry, flow/volume loops, and maximal voluntary ventilation.
• Pulse oximetry module with SpO2 analysis.
• Non-invasive blood pressure measurement (SBP/DBP).
• Single Breath Diffusion capacity (DLCO) module.
• Inhalation systems for allergological provocations, cold air bronchial provocation, and eucapnic voluntary hyperpnoea provocation.

Software Features

• Highly customizable measurement programming and visualization.
• Standard and user-defined parameters with predictive equations.
• Multiple report types including summary reports, ready-to-print predefined reports, and a 9-chart Wasserman report for clinical interpretation.
• Data archiving and export compatible with standard statistical software.
• Real-time data display with customizable graphs and waveforms.
