How to prevent and deal with PICC blockage

The catheter position is correct, and the catheter scale is recorded every time the catheter is changed and applied. Note the aseptic operation, correct positive pressure sealing and pulse punching. Use correct flushing fluid, volume and syringe.

Mechanical tube blockage can be solved by changing the position of the body, catheter reset and other methods. When the tube is blocked by blood coagulation, first try to draw back (not violently to prevent the catheter from rupturing). If not, you can use the method described in the article, but you need to communicate and agree with your family in advance.
