Central venous pressure measurement with patient at different angles Medición de la presión venosa central con el paciente en diferentes ángulos
2016
Objective: to investigate whether central venous pressure values differ with patient bed inclination. Method: this quantitative, ana lytical, longitudinal study was conducted from November to August 2013 at four intensive care units at a large hospital in northwest Sao Paulo. Central venous pressure was measured in 156 patients at four different bed inclinations each, totaling 624 measurements. The data are expressed in absolute and percentage values, variables were analyzed using the Mann-Whitney and Wilcoxon tests, and associations between measurements were tested by Pearson’s correlation coefficient (r). Conclusion: measurements were found to be accurate at 0 o and 30 o (a positive correlation between measurements), but a weak correlation at 0 o
