Key result
Minimally invasive pulse wave analysis devices lack sufficient accuracy to replace reference techniques for hemodynamic management.
Why the study?
Do minimally invasive pulse wave analysis devices achieve sufficient accuracy and trending ability compared to reference techniques in ICU and noncardiac surgery populations?
Meta-Analysis
Do minimally invasive pulse wave analysis devices achieve sufficient accuracy and trending ability compared to reference techniques in ICU and noncardiac surgery populations?
Minimally invasive pulse wave analysis devices lack the accuracy and trending ability to replace reference techniques for hemodynamic monitoring, highlighting the need for standardized validation.
Clinicians should continue using reference techniques for hemodynamic monitoring; confirms need for standardized validation of minimally invasive devices.
Minimally invasive pulse wave analysis devices do not achieve sufficient accuracy or trending ability to be interchangeable with reference techniques. Extreme heterogeneity persists across devices, clinical settings, and methodological quality. Differences associated with conflicts of interest and between ICU and noncardiac surgery populations suggest that performance is context-dependent and influenced by study sponsorship. Taken together with recent evidence and new methodological standards for cardiac output validation, our findings underscore the need for more transparent algorithms, rigorous reporting of trending ability, and standardized validation frameworks before these technologies can be considered reliable for guiding hemodynamic management.
