Abstract

Mean systemic filling pressure (MSFP) is a critical hemodynamic parameter for managing critically ill patients. Existing estimation methods either require invasive procedures or assume constant vascular resistances, limiting their applicability in clinical settings. We propose a novel method to estimate MSFP using cardiac power (CP), this method was developed in a cohort of 50 patients, validated in a different cohort of 50 patients, and tested in a historical cohort of 21 patients, showing a high correlation (r = 0.95 - 0.90) and agreement with Parkin analog Mean Systemic Filling Pressure (MSFPa) method. In brief MSFPe = (3.3*CP) + 2.2 + CVP. Our method provides an accurate, non-invasive bedside approach for estimating MSFP, facilitating hemodynamic assessment in critically ill patients and opening new research avenues on vascular resistance dynamics.

提出一种基于心脏功率估算模拟平均全身充盈压力的新方法。

平均全身充盈压（MSFP）是治疗危重病人的关键血流动力学参数。现有的估计方法要么需要侵入性手术，要么假定血管阻力恒定，限制了它们在临床环境中的适用性。我们提出了一种利用心功率（CP）估算MSFP的新方法，该方法在50例患者的队列中开发，在50例患者的不同队列中验证，并在21例患者的历史队列中进行了测试，结果显示高相关性（r = 0.95 - 0.90），并与Parkin模拟平均全身充血压力（MSFPa）方法一致。简言之，MSFPe = (3.3*CP) + 2.2。我们的方法为估计MSFP提供了一种准确、无创的床边方法，促进了危重患者的血液动力学评估，并开辟了血管阻力动力学的新研究途径。

期刊介绍： The Journal of Clinical Monitoring and Computing is a clinical journal publishing papers related to technology in the fields of anaesthesia, intensive care medicine, emergency medicine, and peri-operative medicine. The journal has links with numerous specialist societies, including editorial board representatives from the European Society for Computing and Technology in Anaesthesia and Intensive Care (ESCTAIC), the Society for Technology in Anesthesia (STA), the Society for Complex Acute Illness (SCAI) and the NAVAt (NAVigating towards your Anaestheisa Targets) group. The journal publishes original papers, narrative and systematic reviews, technological notes, letters to the editor, editorial or commentary papers, and policy statements or guidelines from national or international societies. The journal encourages debate on published papers and technology, including letters commenting on previous publications or technological concerns. The journal occasionally publishes special issues with technological or clinical themes, or reports and abstracts from scientificmeetings. Special issues proposals should be sent to the Editor-in-Chief. Specific details of types of papers, and the clinical and technological content of papers considered within scope can be found in instructions for authors.
