A correlation of central venous pressure (CVP) with peripheral venous pressure (PVP) in different clinical setups has been suggested previously. We aimed to investigate the effect of positive end expiratory pressure (PEEP) on the agreement between central and peripheral venous pressures. After receiving ethical committee approval, we perfomed a prospective repeated measures study was performed on 9 patients in our ICU. Except for the changes in PEEP, ventilatory settings (tidal volume 8 mL kg-1, respiratory rate 12-16 breaths min-1, FiO2 0.40) remained unchanged. CVP and PVP were measured simultaneously at 0, 5, 10, 15, 20 cm H2O PEEP, which was maintained for at least 10 minutes. Three successive measurements (5 minutes apart) were obtained at each level of PEEP. B-land Altman assessment for agreement was used for CVP and PVP in all groups. The patients were 39±26 yrs old, weighing 64±19kg. The APACHE II score on admission was 20±11. Mean bias (CVP-PVP) corrected for repeated measurements was -7.98±7.38 mmHg. All measurements were within Mean±2SD limits demonstrating a good agreement between CVP and PVP measurements. PEEP did not influence this agreement. We conclude that PVP measurement may be a noninvasive alternative for estimating CVP in selected clinical situations in the ICU such as the application of PEEP, which does not interfere with the agreement of CVP and PVP.
