It might have seemed weird that someone blew a hole in Medea Station and Devon and Melissa weren’t immediately sucked out. But the reality is, unless your right next to the hole, the pressure difference between breathable atmosphere and vacuum won’t suck you out of anything. Certainly, it’s usually nothing like the movie scenes where people are blown out of a space-ship and have to hang on. There are a few rare instances where this could happen but what’s a lot more likely is you hear a rushing noise, feel a breeze then the air is gone and you suffocate in under seconds. I know some of you absolutely don’t believe me at this point, so I’d like to point you to an awesome real world test done by the Mythbusters. They did their test at about 8psi, a little more than half of standard atmospheric pressure, 14.7psi, but it should demonstrate the point.

In Devon and Melissa’s case they have a foot or so wide hole in a fairly large room that’s also being fed fresh air from the hallway. Depending on the size of the room they would have about 30 seconds to a minute to escape before they lose consciousness.
It’s also worth noting that small pinhole leaks in a ship, can actually be plugged by something as simple as your finger. I don’t suggest trying it or you’ll end up with one very sore, swollen finger, but human skin is a surprisingly good pressure vessel in a pinch.
