You can apply May 2006 library - "Not a funny scene indeed" emitter.
Alter this emitter:
* decrease the f-life to about 30 I guess
* remove the subemitter "light"
* increase the number of subemitter "cloud" to about 300
* change the color of "cloud" to dark red completely.
* change the shape(texture) of cloud to "blur" image
For the directional blood explosion:
* decrease the emission range, preferably below 40.
* adjust the emission range, this affects the emitting direction.
