Technicaly you can make them stay forever but it isn't a good idea as they will severely impact proformance after a while.
The reason is because the blood splats are currently implemented using the particle system. When a particle impacts, it's movement is stopped and it's aligned perpendicular to the surface it hits.
In a future Doomsday a proper decal system will be implemented so that blood and other effects can last forever with hardly any impact on performance.
If you want to increase the time they last anyway, open up the DED that has them and increase the Max age parameter of the various blood generators
