TYPES OF EUTHANASIA
Voluntary Euthanasia refers to the action taken by the physician and the patient, who both agree (with informed consent) to end the patient's life.
Involuntary Euthanasia refers to a third party taking a patient's life without the informed consent of the patient. This is commonly practiced in veterinary medicine when animals are "put down" or "put to sleep." In modern medicine, it could conceivably be applied to the act of taking a terminally ill, suffering patient's life that has lost all mental capacity to make his/her own decisions.
Also Known As: physician-assisted death, physician-assisted suicide, mercy killing
Indirect- Providing treatment (usually to reduce pain) that has the foreseeable side effect of causing the patient to die sooner. The patient dies sooner as a side effect of giving a medical treatment given to relieve pain or improve end-of-life symptoms. Indirect or passive euthanasia are not prohibited in most countries, while direct or active euthanasia is prohibited; these are considered by some to be incorrect terms because they are not really types of euthanasia.
Passive- Involves withdrawing or withholding life-prolonging
