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 doses transfused
- 1
- Cryoprecipitate doses transfused
- 0
Result: Ratio 6:4:6 (1 apheresis platelet dose counts as 6 units); 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, with 1 apheresis platelet dose counted as 6 units (6 PRBC : 6 plasma : 1 dose).
- Cryo cadence
- 1 pooled dose every 6 PRBC per ATLS 2018.
What you enter
- PRBC units transfused
- FFP / plasma units transfused
- Platelet apheresis doses transfused (1 dose counts as 6 units in the ratio)
- Cryoprecipitate doses transfused
