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 insertion see video http://up.top4top.net/d_5fb3815cd31.flv __________________ ![]() |
