This room that I am working on right now will be used for recording
and will be about as soundprooof as I can get it without going too
overboard cost wise. So, to me, that means that it is going to be very
air tight too.

The thing about his house is that there are no furnace air returns in
the whole upstairs. So I only have one heat vent in this room and no
air return.

I don't need the vent for heat but will need to use the air
conditioner in the summer. I can just open the door and let the room
cool down and then not need the air conditioner much for a while when
I close the door even tho the Air will still be on. I can also turn on
the fan in the winter even tho I will be using a space heater
(probably a radiator type because they are quiet) to heat up the
room.

So the question is will the furnace fan blow much air into an airtight
room that has no air return or at least an opening for the air that is
already in the room to go to? If I just open the door for a while
every half hour or hour or something like that would that be enough to
keep enough oxygen in the air so I don't pass out or worse?

There's also going to be a concern too if the house is sold sometime
in the future when I am not around and no one gets told how air tight
that room is and they use it for a bedroom or something.

Well crap. I think I just talked myself into figuring out a way of
getting an air return set up in that room. Better safe than sorry.

No return in a airtight room means a stuffy mess. What is total power
consumption of everything you will have on, even lights because its
all going to be converted to heat, even the Btus people put out. In
summer you will need more Btu cooling then before if your walls have
been upgraded for sound deadining, you wont need as much extra heat in
the winter but you need to move air in and out.
