That's why Purple Banana was advising you to take a CPR class, MGC, because once you learn proper CPR technique, you'll know there's no pushing-out of air necessary. The lungs deflate on their own with the chest compressions. You'll also learn the proper positioning and placement of an unconscious person's head and neck so as to secure an open airway instead of simply blowing air in, which you likely did into her esophagus instead of her trachea.

Purple Banana, you've clearly had an impressively high success rate with CPR. You must have done it on an awful lot of people to get six successes.
