Can family members be in the same room with a coding patient?

No, they cannot be.

If a patient is "coding", which means they require resuscitation, the family will be told to leave the room. Refusal will result in the calling of security or a nearby police officer, whichever is nearest.

The reason family cannot stay in a room while a patient is being resuscitated is because aside from being extremely stressful to see, the family will be in the way. They would be crying and yelling (so the doctors can't hear each other clearly) and trying to get to the patient (getting in the way of the doctors, tripping on equipment), which will just slow down the doctors and lower the patient's chance of survival.
