A patient is undergoing monitoring for hemodynamic stability in the intensive care unit. Their central venous pressure (CVP) is being recorded to assess their intravascular volume status. A nurse notes that the CVP reading is ___ mmHg, indicating adequate preload in the context of left ventricular function.
Refer to the normal range for CVP to fill in the blank accurately. Normally, a CVP reading between 2 and 6 mmHg is considered indicative of normal central venous pressure.
