Bloodstain Pattern Analysis Terminology - IABPA - Bubble Rings
Note: At the 2009 IABPA meeting in Portland, OR, USA, the IABPA membership voted to adopt the SWGSTAIN recommended terminology.
- Bubble Rings
- Rings in blood that result when blood containing air bubbles dries and retains the bubble's circular configuration as a dried outline.
Bloodstain Example - Bubble Rings

The example was generated by aerating the blood and projecting it onto the target.
In this example several air bubbles formed in a single blood drop. When the stain dried, the
bubble collapsed and a darkened ring was left behind for each bubble.

|James, Kish & Sutton||May be a criteria for Spatter - Projection Mechanism - Expirated|
|Wonder||Not a pattern.|
