2scents, Im not sure what you mean. There is usually no discernible difference between a patient in whom “death is obvious” and a patient who suffered a recent arrest.
Do you mean after time has passed?
At any rate of the top of my head a patient in who cardiac arrest occured as a result of refractory hypotension or in a patient in whom cpr has been ineffective. Or if the home’s policy is not to perform CPR and residents are aware of this and agree to it.
