Central venous pressure (CVP) is important indicator of the adequacy of fluid resuscitation. Failure to rapidly achieve or maintain a CVP >8 mmHg has been correlated with a poor prognosis in severe sepsis and septic shock (3). A target CVP range of 8-12 mmHg is ideal. In mechanically ventilated patients on positive end expiratory pressure (PEEP), the target should be adjusted to at least 12-15 mmHg to compensate for increases in intra-thoracic pressure.
