Ethically, there are arguments for and against keeping dying people on life support. The main argument in favor is that, by keeping patients alive, it allows time for either the patient to recover or medical practitioners to explore other options. While this can be a source of hope for the dying patient's family, some argue that in many cases life support merely prolongs their grief with ultimately false hope, reports the ACLS Training Center.
There are moral arguments for and against as well, explains the ACLS Training Center. Those in favor of keeping dying patients on life support argue that allowing a patient to die is morally wrong, while those against maintain that prolonging suffering, particularly without consent, is morally more problematic.
