My Buying Guides on Green Caps For Picc Lines
What I Look for First
When I shop for green caps for PICC lines, my first priority is always compatibility. I make sure the cap fits the specific PICC line and connector type I’m using, because a poor fit can lead to leaks or contamination. I also check whether the cap is designed for positive pressure, since that can help reduce blood reflux.
