How much heparin to flush a port a cath?

To flush a port-a-cath, a typical recommendation is to use 10 mL of normal saline followed by 3 mL of heparin (usually at a concentration of 100 units/mL) to maintain patency. However, specific protocols may vary based on institutional guidelines or patient-specific factors, so it's essential to follow the healthcare provider's orders and the facility's policies. Always ensure to verify the dosage with the latest clinical guidelines or a healthcare professional.
