PROCEDURE Central Venous Catheter Insertion (Perform)

WebCentral venous pressure is an assessment of venous return, blood volume and, indirectly, of cardiac output. Normal CVP is between 0 and 8 cmH2 O (1–6 mmHg). In a hypovolemic foal, CVP is often 0 cmH 2 O or less. Evaluating a response to fluid therapy (a progressive increase in CVP) is helpful in determining if fluid replacement is adequate. WebBlood loss can occur when a connector is: inadvertently disconnected from the catheter lumen, cracked or broken during use and/or failed during use and the catheter lumen is not clamped. Depending on the patient’s venous pressure, the location/vein chosen for catheterization and the catheter size, the resulting blood loss can be mild to severe.
