Goofs

When Nelson is attacked in the back of the Jeep, Labraccio smashes in the drivers side window to get to him. Later the window is suddenly whole again.

In the scene where Rachel stares into the mirror, the writing on the wall under the mirror changes.

When David and Nelson go to visit Winnie Hicks, the Jeep's window is alternately rolled up and down and then back up again between shots.

When Nelson first goes under, the electrodes attached to his ears go from barely stuck on by the tips of the pads, to fully stuck on.

When everyone is preparing to put Nelson under for the first time, Nelson squeezes the syringe squirting fluid out of the needle then taps on the syringe to force any bubbles to the top of the syringe. This is the opposite of the way you actually get all of the air out of a syringe.

Defibrillator only works properly against bare skin. The proper medical procedure requires removal of clothing and undergarments around the chest prior to application.

No people who have had near death experiences were actually brain dead. It is understood that these experiences are generated in the brain. Yet the experiences of the flatlined medical students are said to occur after they are declared brain dead. If that is so, they could not be bought back to relate their visions, since brain death is irreversible, as any medical student should know.

During the Gross Anatomy dissection, the medical students are told to remove the ascending colon to the transverse colon, then to continue to the sigmoid colon until reaching the appendix. The appendix is located on the right side of the colon, at the beginning of the ascending colon. The above description would put it on the left side, near the end of the sigmoid (the last part of the colon before the rectum).

A person who has flat-lined cannot be revived with a defibrillator.

While a defibrillator is of no use if a patient has truly flatlined, a patient in a "fine v-fib" rhythm can appear to have flatlined but still be revived with the paddles. Therefore, when in doubt, the Advanced Cardiac Life Support guidelines call for administering the shock, though it's not the treatment of choice.

When Rachel goes to inject Nelson in the neck, the syringe close-up reveals a spring contracting inside the casing. This is an often used prop that lets needles retract into the syringe and then come back out when pressure is released.

In the bathroom scene with Rachel and her father, the walls can be seen sliding back in order to make the set bigger for the 360 degree camera sweep.

Nelson prints a document on a laser printer which makes a sound like a dot-matrix printer.

When the camera zooms into the EKG meter, you can clearly see the camera and crew reflected in the glass of the monitor.

When Joe walks home (after the scene when David visits his old schoolyard), along with the guys carrying the big posters, the steadicam operator and the focus puller are reflected in a store window of the house.

When Joe and Steckle enter the cemetery while chasing Nelson, the spooky mist is too obviously coming from smoke pots located behind tombstones in the shot.

Mannus's father was apparently right-handed and shot himself in the temple, which means he held the gun in his right hand and pressed it to the right hand side of his head while sitting in the driver's seat of his truck. Yet the hole left by the bullet after it exited his head is in the middle of the truck's windshield, while it should have been in the driver's door window. It's not physically impossible for the hole to be where it is, but he would have had to be sitting twisted around to his right and on the edge of the car seat to give his arm room to lift the gun to his head, which is a very awkward position.

We see Nelson take potassium chloride from the bottle and inject it right into his arm. But the way one does it, is to draw blood from the arm into the syringe top where it mixes with the blood. Then the whole mixture is injected back into the body. A medical student would know this.

In a couple of scenes, Rachel is compassionately tending to and trying to comfort the dying, elderly woman patient. However, after she experiences the downside (initially) of flat-lining she rushes over to tell the woman that death is not, actually sweet and beautiful (though she discovers that the woman has died.) After having been so compassionate to the woman earlier, it makes no sense that she would then want to terrify the poor, dying woman.
