wake me up by a loud shout

[theol]

My friend came to rescuer me from the burning house but he got burned. He is very brave, but next time he could wake me up by a loud shout and call out for help.

Are these sentences correct, especially the second one " He is very brave, but next time he could wake me up by a loud shout and call out for help."?
is there any word I can use instead of "loud shout"? I just try to describe a situation which is" wake someone up using loud voice"

You could use something like "... he should yell to wake me up".

"Yell" means "to shout loudly" so it's tautologous to say "yell with a loud shout". You specifically said you wanted a word to use instead of "loud shout" and then you used it again!
