Please note: This is a Sole Source Notification. Commodity or commodities to be purchased (make, model, description): PHYSIO-ENDURO - PhysioFlow Enduro Wireless Cardiac Output System with Starter Kit Includes: - PhysioFlow Enduro device - sensor kits (40 subjects) - skin gel - USB serial adapter (2), RSS232 dual adapter - OMNIA AUX Devices Integration Module (A-670-100-023) for use with OMNIA; Explanation of the need to be fulfilled by this item(s), how is it unique from all other options, and why it is the only one that can meet the specific needs of the department: The PHYSIO-ENDURO - PhysioFlow Enduro Wireless Cardiac Output System with Starter Kit is essential for enhancing the Department of Kinesiology’s research capabilities related to non-invasive cardiovascular monitoring and assessment of cardiac output during exercise and rest. This system offers a unique combination of portability, precision, and real-time data collection that is not found in other similar devices. The PhysioFlow Enduro provides the following unique features: Wireless Design for Real-Time Monitoring: Unlike traditional, lab-bound cardiovascular assessment systems, the PhysioFlow Enduro provides wireless, continuous monitoring of cardiac output, stroke volume, heart rate, and other key hemodynamic variables in real-time. This portability allows for testing in laboratory environments, athletic training facilities, and fieldbased research, enhancing versatility. Non-Invasive Measurement: Provides a safe, reliable, and non-invasive method for assessing cardiac output without the need for invasive catheters or imaging techniques. Dual-Use Capabilities: Suitable for both exercise testing and clinical assessments, making it a comprehensive tool for a wide range of research and educational applications. Compatibility and Integration: The PhysioFlow Enduro integrates seamlessly with existing departmental research systems and data analysis tools, facilitating efficient data collection and interpretation. Validation and Peer Acceptance: This system is widely recognized and validated by peer-reviewed studies for its accuracy, reliability, and usability across various populations and research settings. Other commercially available systems, such as Doppler Ultrasound and inert gas rebreathing systems, are either invasive, impractical for field-based research, or unable to provide continuous, real-time data during exercise. The PhysioFlow Enduro Wireless Cardiac Output System is the only device that offers a combination of wireless functionality, high-resolution impedance cardiography, non-invasiveness, and dual-use capability required for the department’s research and teaching activities.
