I did a brake fluid flush for the first time on my Ranger today. I used a Motive Power Bleeder. Everything went great until I got to the last wheel: I had the bleeder screw open, letting the fluid flow out. I checked the power bleeder to check the pressure and I saw that it was just about empty. (Lots of bubbles in the plastic tube, which in itself is not a big deal, but running out of fluid is) In a panic and not really thinking straight, I unscrewed the cap of the bleeder to release the pressure....while the bleeder screw on the brake was still open. The second I unscrewed the cap I realized my mistake and quickly tightened the bleeder screw. By this time I was pretty much done anyway so I went for a test drive. The pedal feels fine, just as firm as it's always been. I can stop quickly no problem and the pedal does not sink to the floor. So, should I worry about air in the lines and do I have to bring it to a shop to bleed it out? I know the ABS pump complicates the bleeding process if it's before the pump. I'd really like to think that since the pedal feels fine I don't need to do anything, just looking for some reassurance.
Brake fluid flush...did I totally screw up?

As a general rule if you get air in the lines you will know it...

Correct, which is why I said the bubbles weren't really a problem. Motive however warns "do not let the bleeder run out of fluid!" so that's what set me into the panic. My main concern is with letting the pressure out of the bleeder while the bleeder screw was still open. I would imagine it's basically the same thing as taking your foot off the brake pedal while the bleeder screw is open, doing it the old fashioned way. (Right?)

Your front left may have air ,not in the sense of actual breathable air ,but air in the sys., just bleed the front left only and then report back. K?
If I am doing a quick bleed as opposed to a flush, I do not put any fluid in the motive (because I'm lazy and don't want to clean it), I do make sure that the res does not drop below the min level. If you still had enough fluid in the resevoir, it should be fine.
O'l fashion bleeding will be fine.
When you released pressure, you reverted to a gravity bleed.
You should be just fine.
But I don't think you will really feel secure until you bleed them again.
