Elderly people may have symptoms in the days before their death in terms of their state of mind, diet, respiration, heart rate, and diaphoresis, such as drowsiness, poor appetite, cardiac arrhythmia, and urinary and fecal incontinence. 1. Spirituality: patients often appear drowsy, confused, or even deep coma (patients appear to have fixed dilated pupils, light reaction disappears, brainstem reflexes disappear, muscle tone decreases). 2. Diet: patients develop anorexia and poor appetite, which gradually develop into inability to eat, and need to rely on fluids to maintain nutrition. 3. Heart rate: arrhythmia, compensatory increase in heart rate, followed by a gradual decline and eventual arrest. 4. Respiration: the respiratory rate increases, gradually weakens and stops at the later stage, and the oxygen saturation gradually decreases. 5. diaphoresis: the patient is incontinent due to the relaxation of the urethra and anus. However, the time of death cannot be inferred from the symptoms. If the elderly have the above symptoms, they should be actively examined and treated.
