Massive Transfusion 1:1:1 ratio tracker (PROPPR)

Massive-transfusion-protocol ratio tracker: from the PRBC, FFP/plasma, platelet, and cryoprecipitate units transfused, returns the running PRBC.

Open the tool → Runs in your browser. Data leaves only if you deliberately send a problem report from the interactive tool.

Example

PRBC units transfused
6
FFP / plasma units transfused
4
Platelet apheresis units transfused
1
Cryoprecipitate doses transfused
0

Result: Ratio 6:4:1 below PROPPR 1:1:1 target; next product FFP; 1 cryo dose due per ATLS 2018.

The tool opens with these values already filled in. Replace them with your own.

What the result means

PROPPR target
PRBC : FFP : Platelets = 1:1:1.
Cryo cadence
1 pooled dose every 6 PRBC per ATLS 2018.

What you enter

  • PRBC units transfused
  • FFP / plasma units transfused
  • Platelet apheresis units transfused
  • Cryoprecipitate doses transfused
