Unfortunately, there isn't really simultaneous co-op.
The dungeon-crawling aspect of the gameplay is based largely around missions, right? Things like 'rescue pokemon A from dungeon B,' 'deliver item C to pokemon D on level E of dungeon F,' 'retrieve stolen item G from thief pokemon H'...so on.
So if your team faints in a dungeon, you can send out for help. Essentially, you're creating a mission that someone else can go on to rescue your team. You can do this wirelessly, via wifi, or by creating a password.
I don't know the details beyond that, because I haven't actually done a wifi/wireless/password rescue, from either end. I'm assuming that if your team gets rescued in this way, you don't lose all your items and gold like normal. I don't know how rewards are set up, but I know there's an option for sending a "thank you" mail, which may give you the option for sending an item with it.
