Health stages: Blood UI based on Health

I want a way to play different animations when the health is lower than a number for example: under 60% the blood ui’s transparency would be 0.8 then under 35% it would have a transparency of 0.5 then under 5% it would ragdoll (just an example).

Right now I only got the blood ui to work when your health is halved but I don’t know how to multiple health stages.
