    Central line placement

    The central venous pressure (CVP) is the pressure measured in the central veins close to the heart. It indicates mean right atrial pressure and is frequently used as an estimate of right ventricular preload.

    The CVP catheter is an important tool used to assess right ventricular function and systemic fluid status.

    What is a central venous catheter?

    A central venous catheter, also called a central line, is a long, thin, flexible tube used to give medicines, fluids, nutrients, or blood products over a long period of time, usually several weeks or more.


    Normal values are 5-10 mmHg

    Factors affecting CVP

    Factors that increase CVP include:

    Hypervolemia
    forced exhalation
    Tension pneumothorax
    Heart failure
    Pleural effusion
    Decreased cardiac output
    Cardiac tamponade
    Mechanical ventilation and the application of positive end-expiratory pressure (PEEP)
    Pulmonary Hypertension
    Pulmonary Embolism

    Factors that decrease CVP include:

    Hypovolemia
    Deep inhalation
    Distributive shock

    Indications for the use of central lines include

    Monitoring of the central venous pressure (CVP) in acutely ill patients to quantify fluid balance
    Long-term Intravenous antibiotics
    Long-term Parenteral nutrition especially in chronically ill patients
    Long-term pain medications
    Chemotherapy
    Drugs that are prone to cause phlebitis in peripheral veins (caustic), such as:
    Calcium chloride
    Chemotherapy
    Hypertonic saline
    Potassium chloride
    Amiodarone
    vasopressors (e.g. epinephrine, dopamine)
    Plasmapheresis
    Peripheral blood stem cell collections
    Dialysis
    Frequent blood draws
    Frequent or persistent requirement for intravenous access
    Need for intravenous therapy when peripheral venous access is impossible
    Blood
    Medication
    Rehydration
