Abstract 【Objective】To investigate the correlation and consistency between peripheral venous pressure and central venous pressure in patients with severe heart failure with invasive ventilation.【Methods】Patients with severe heart failure who received invasive ventilation in the intensive care unit from January to December 2021 were selected as the study subjects. When central venous pressure (CVP) was measured for the first time in each patient, peripheral venous pressure (PVP) was measured simultaneously through the median of the elbow or the main vein. Pearson correlation analysis was used to analyze the correlation between CVP and PVP. Bland-Altman method was used to analyze the consistency of CVP and PVP.【Results】Pearson correlation analysis showed that there was significant linear correlation between CVP and PVP (r=0.93, P<0.05). The linear regression equation was y=0.98x-0.44 (y was CVP, x was PVP; F=846.02, P<0.05), calibration determination coefficient R²=0.87. In 138 patients, the measured values of CVP and PVP were (11.53±5.70) mmHg and (12.28±5.46) mmHg, and the 95% conjunctive limit was from -4.8 mmHg to 3.3 mmHg. Bland-Altman analysis showed that CVP had good consistency with PVP.【Conclusion】PVP and CVP have good correlation and consistency. For patients with heart failure receiving invasive ventilation, PVP and CVP are a rapid, reliable and non-invasive assessment index of volume status.
