Najafi Q&A: Clinical Death

My mother is in the hospital and she is breathing through the respiratory system, which I cannot bear the costs, and her brain stops working and doctors advised me to turn off the device because she is dead by a high percentage. If the device is turned off, she will die completely. Is it permissible to turn off the device because it is too expensive?

There is in the medical law the issue of non-resuscitation, so that the patient whose death have been confirmed by the doctors, can request not to be resuscitated in case his heart stops working. The resuscitation is done by pressing on his chest, putting an artificial respiration machine, electrocution, etc. used. If we ask medical experts, they say that this patient can be resuscitated, but his death is inevitable after an hour, day or week, and it is often a very arduous process for the patient to resuscitate in addition to the pain that he will suffer in most of the times. Hence, this law was issued, which allows the patient to choose not to be resuscitated, since his death is inevitable and he is in a very advanced state of illness and pain, so it is preferable to be left in this case. We would like to get the legal ruling for this matter clarified, given that it is applied in some of our Islamic countries and consider the medical matters that I mentioned, as this issue is a problem.
