The symptoms before the death of an elderly person often include the following: i. The patient is in a coma and can answer when called, but soon falls into a coma again. The patient has no energy or stamina for normal communication because of the extreme lack of energy and insufficient supply of energy to the brain. Second, the limbs gradually change from soft to stiff. This is a lack of energy supply to the muscle cells, which manifests as a state of continuous contraction. III. Monitoring the patient’s blood pressure, heart rate, and pulse is almost impossible because the patient’s heart almost stops beating. Fourth, the condition of urinary and fecal incontinence in the elderly is mainly due to the inability of the anal or urethral sphincter to maintain a state of contraction and complete relaxation resulting in the patient’s urine and feces being discharged on their own. Patients may die at any time once the above symptoms appear.
