Corrected entry: At one point while the group is trying to bring back Rachel the power goes out and they freak as they can't defib. However, this is a portable defibrillator used by ambulance personnel which has its own power source. The only trouble they might have is they can't see as well.
Corrected entry: During the defibrillation scenes, the 'doctors' rub the paddles together before delivering the electrical shock. Yet there is no gel on the paddles, and no gel pads on the 'patient' either.
Corrected entry: Towards the end when Kiefer Sutherland goes under for the second time and the others rush in to find him, they need injections to aid in his revival. Julia Roberts tells the others that she is injecting "epi. intracardial" and plunges the needle into Sutherland's chest. The area where she sticks the needle IS where the heart should be, however, the heart is surrounded and protected by the sternum bone. If she was trying to inject it into the heart, shouldn't she have done so from a different angle? It DOES appear that the needle went through, but that would have to be a very strong needle to be able to not break, hitting bone.
Corrected entry: In the final scene, Julia Roberts comes charging in to explain to the group that Kiefer Sutherland called her to tell her of his plan to flatline and that was about 9 minutes ago. So in an important plot line, everyone uses that number as the amount of time Kiefer has been under. But by the time he made the call to the time he actually ran into the abandoned church, turned on all the equipment, set himself up and eventually injected potassium into his arm, you'd have to figure at least 2-3 minutes elapsed before he actually flatlined. Why didn't the group take that into account?
