Course description

Tammy Sparacino, CCP lectures on non or minimally invasive cardiac output devices. 

The panel discusses the advantages and challenges that these devices pose in regards to accuracy and dependability, especially in artificial circulatory support and ECMO. 

Understanding Non-Invasive Cardiac Output Monitoring in Artificial Circulatory Support and ECMO

In the realm of critical care, particularly concerning artificial circulatory support systems such as Extracorporeal Membrane Oxygenation (ECMO), the utilization of non-invasive cardiac output monitoring devices represents a significant advancement in patient management. This comprehensive discussion sheds light on the integration and implications of these technologies, their underlying principles, and their application in clinical settings to enhance patient outcomes.

Overview of Hemodynamic Monitoring

Hemodynamic monitoring is pivotal in assessing the cardiac output and organ perfusion, crucial for stabilizing patients across various medical conditions. Initially, it involves basic monitoring techniques such as measuring heart rate, arterial pressure, and other physiological parameters. However, the critically ill, especially those in intensive care, require advanced monitoring to accurately assess their dynamic circulatory status.

The Shift Towards Non-Invasive Technologies

Recent advancements have seen a significant shift from invasive to non-invasive monitoring methods. The conventional invasive methods, although effective, pose risks and discomfort to the patient. Non-invasive cardiac output monitoring techniques, such as those utilizing pulse pressure analysis or Doppler systems, provide a safer alternative, reducing the risk associated with traditional invasive methods.

The Role of Non-Invasive Devices in ECMO

In ECMO settings, where patients often present with complex hemodynamic profiles due to their critical conditions, non-invasive devices play a crucial role. These devices provide real-time data on cardiac output and other vital parameters without the need for direct vascular access. This capability is especially beneficial in managing patients with varying levels of cardiovascular instability, where rapid and accurate data is essential for effective treatment adjustments.

Specific Devices and Their Applications

Several non-invasive devices have been highlighted, such as the ClearSight system and the Nexfin monitor. These devices use finger cuff technologies to derive arterial pressure waveforms, which are then analyzed to estimate cardiac output. This technology provides continuous monitoring which is vital for the dynamic assessment of patients under ECMO support.

Additionally, devices like the LiDCO and FloTrac systems utilize different methodologies to achieve similar outcomes. These systems, which rely on pulse pressure analysis, offer another layer of data critical for making informed clinical decisions. These devices are particularly useful in settings where quick adaptation to patient needs is crucial, such as during surgical procedures or in the intensive care unit.

Clinical Implications and Future Directions

The integration of non-invasive monitoring devices in clinical practice offers several benefits including reduced risks of infections, quicker setup times, and improved patient comfort. However, these technologies are not without limitations. The accuracy of these devices can be influenced by various factors such as patient movement, specific medical conditions, or technical anomalies.

Future advancements in non-invasive cardiac output monitoring should focus on enhancing the accuracy and reliability of these devices. Continued research and clinical trials are necessary to refine these technologies, ensuring they provide reliable data across a broader spectrum of patient conditions and clinical settings.


Non-invasive cardiac output monitoring represents a transformative advancement in the management of patients with artificial circulatory support, including those on ECMO. As these technologies continue to evolve, they promise to further enhance the capabilities of medical professionals in critical care environments, leading to better patient outcomes and streamlined clinical operations. The ongoing development and clinical integration of these devices will undoubtedly play a pivotal role in shaping the future of patient monitoring in high-stakes environments.
