2 week old...breathing?

My son is two weeks old and tonight he has been breathing strangely. He is very wheezy and nasally. He does no seem to be bothered by it, but i cant sleep with him breathing like that it worries me. The hospital never sent me home with one of the nasal aspirators so i dunno what to do. is there anything i can do to try to help him? He does not seem bothered by it, but his breathing seems a little labored.
