Child breathing out loudly?

My daughter has has a really heavy head cold for a week,it is improving but since having it she is breathing out quite heavily,it is quite odd almost like your trying to blow air up to your nose if you know what i mean,this isn't every breath just random through out the day and initally at night when sleeping when it was at its worst

her asthma has been pretty steady for a few years now

Is this just being bunged up or her asthma?

thanks

Hi there

it does sound like her recent cold has probley triggered her asthma.. just to be on the safe side take her to your gp hopefully he will put your mind at rest.. My neice started air yawning as the gp called it and he diagnosed a chest infection and increased her preventer now shes much improved.. x
