Relationship between inferior vena cava diameter ratio and central venous pressure

Purpose To explore the relationship between the shape of the inferior vena cava (IVC) lumen and central venous pressure (CVP). Methods In 60 patients undergoing mechanical ventilation and CVP monitoring in the Intensive Care Unit of Peking Union Medical College Hospital from July to October 2016, we...

Zusammenfassung:	Purpose To explore the relationship between the shape of the inferior vena cava (IVC) lumen and central venous pressure (CVP). Methods In 60 patients undergoing mechanical ventilation and CVP monitoring in the Intensive Care Unit of Peking Union Medical College Hospital from July to October 2016, we measured with B‐mode ultrasonography the transverse maximum (MXD) and minimum diameter (MID) of the IVC at end expiration, and calculated the diameter ratio (DR) as MXD/MID. Patients were divided into three groups according to CVP: low (CVP 10 mm Hg). Results MXD was 2.32 ± 0.41 cm, MID was 1.41 ± 0.40 cm, and DR was 1.76 ± 0.49. CVP was 9.27 ± 2.99 mm Hg. DR correlated with CVP (r = −0.527, P
