This research aims to assess how lateral positioning affects the accuracy of central venous pressure (CVP) in relation to right atrial pressure (RAP) in ICU patients.
Included 16 sedated, mechanically ventilated ICU patients with central venous catheters.
Measured RAP via solid-state catheter in various positions: supine, left lateral, and right lateral.
Assessed agreement between RAP and CVP using Bland–Altman analysis and intraclass correlation coefficients.
In the right lateral position, CVP accurately approximated RAP (bias -0.4 mmHg; ICC 0.85).
In the left lateral position, CVP overestimated RAP (bias -2.2 mmHg; ICC 0.58).
RAP increased in right lateral position compared to supine (Δ +2.9 mmHg, p < 0.001) and left lateral (Δ +2.8 mmHg, p < 0.001).
