Purpose: This study aimed to evaluate the effects of acute hyperventilation on central venous-to-arterial carbon dioxide tension difference (Pv-aCO), central venous oxygen saturation (ScvO), central venous-to-arterial CO difference/arterial-central venous O difference ratio (COGAP-Ratio), and peripheral perfusion index (PI) in hemodynamically stable critically ill patients.
Methods: Fifty-four mechanically ventilated patients were evaluated. The cardiac index, Pv-aCO, ScvO, COGAP-Ratio, PI, and arterial and venous blood gas parameters were measured in the first set of measurements. Read More
