Good correlation between mixed and central venous oxygen variables in both hyperdynamic and normodynamic states

ABSTRACT

This study was undertaken to assess whether or not central venous oxygen variables [CvO2] measurement can replace mixed venous oxygen variables [MvO2] measurement in two clinical settings, hyperdynamic kidney recipient [KR] and normodynamic patients subjected to radical cystectomy [RC]. MV and CV oxygen tension [PvO2], saturation [SvO2] and arteriovenous O2 content difference [a-vDO2] during the perioperative period of kidney transplantation [10 patients, 69 samples] and radical cystectomy [10 patients, 83 samples] under different FiO2 [0.21-0.35] were compared. The findings of this study demonstrate strong correlation between MvO2 and CvO2 variables in both hyperdynamic and normodynamic clinical settings
