Study Notes
Central Line: Functions
** Administration of Medications and Fluids **
- Allows for continuous or intermittent infusion of medications, fluids, and nutrition
- Enables precise control over infusion rates and volumes
** Hemodynamic Monitoring **
- Measures central venous pressure (CVP) to assess fluid status and cardiac function
- Allows for monitoring of cardiac output and systemic vascular resistance
** Blood Sampling **
- Provides a convenient and safe way to collect blood samples for laboratory tests
- Reduces the need for repeated venipunctures and associated complications
** Other Functions **
- Can be used for hemodialysis and plasmapheresis
- Enables the infusion of blood products and platelets
- Facilitates the insertion of other devices, such as pulmonary artery catheters and pacemakers
