Central venous versus esophageal pressure changes for calculation of lung compliance during mechanical ventilation

Randomized studies are still necessary

“…7 Last and most importantly, the clinical value of intraoperatively measured CVP is also questionable. 8 CVP differs from transthoracic pressure. 8 Transthoracic pressure takes into account factors likely to alter CVP.…”

“…8 CVP differs from transthoracic pressure. 8 Transthoracic pressure takes into account factors likely to alter CVP. 7 For example, intraoperatively, CVP is altered by the pressure of surgical retractors on the thorax and on the right atria.…”

“…Ascites itself is likely to increase intrathoracic pressure and to alter CVP. 5,8 In conclusion, taking into account these methodological drawbacks, data produced by Massicotte et …”

“…7 For example, intraoperatively, CVP is altered by the pressure of surgical retractors on the thorax and on the right atria. 8 Mechanical ventilation and variations in patient positioning are also likely to change CVP. 8 More specifically, CVP has no meaning in a cirrhotic patient with ascites.…”
