yes. u just pump out the same air, it's moist and heated to body temp. its the convection that results in ur feeling you are blowing out hor or cold air
on the other hand if you breathe in and out rapidly (hyperventilate) you will not move the air all the way into your lungs before expiring it thus maybe blow out cold air... which is not what your question was i think.
