Answer

Maintaining a low-normal intravascular volume may be facilitated by hemodynamic monitoring with a central venous or pulmonary artery (Swan-Ganz) catheter, aimed at achieving a central venous pressure (CVP) or PCWP at the lower end of normal. The ARDS clinical trials network of pulmonary artery catheter versus CVP to guide fluid management in ARDS showed no difference in mortality or ventilator-free days, regardless of whether fluid status was monitored by pulmonary artery catheter or CVP.
