There is no clinical term for the 19 signs of “cancer dying”. “In fact, not only cancer patients, but also all dying people will have these conditions. 1. Decline of vital signs 1. Body temperature: Cancer patients may experience the spread of cancer cells throughout the body in the late stage, resulting in the near failure of body organs and the abnormal function of thermoregulation center, which can no longer maintain normal body temperature, and the decrease of cellular heat production function, which can lead to the symptoms of declining body temperature, more obvious in the extremities; 2. Pulse: pulse is also known as arterial pulsation, which is generally the same as the frequency of heartbeat, when cancer patients are dying The pulse rate may be weakened or even stopped due to heart failure, resulting in a weak and feeble pulse, which may not even be easily detectable, and the frequency may be lower than 60 times/min. 3. Respiration: The respiratory rate decreases, usually in the form of jaw breathing, and there may also be difficulty in breathing. Due to heart failure, the blood pressure of cancer patients may drop rapidly before the end of life, generally below 90/60mmHg, or even the blood pressure cannot be measured; 5. Blood oxygen saturation: Due to respiratory failure, the body is hypoxic, and the blood oxygen drops significantly, which may appear suddenly until the blood oxygen saturation is 0%, and the decrease of blood oxygen saturation may also show the manifestation of mucous membrane cyanosis in the mouth, lips and nail bed. 2. Change of consciousness before the break of breath, cancer patients usually present a dark state, which may change from wakefulness, blurred, drowsiness, lethargy, light coma, etc. to deep coma directly. It may gradually change from wakefulness to lethargy, but can be awakened, and then progress to unawakenable, even painful stimulation can’t make the patient awaken. Neuromuscular changes: At this time, all nerve reflexes are weakened or even disappeared, muscle tone is also gradually weakened or disappeared, and there may be no response to painful stimulation, no response to call, pupils are enlarged, etc. There may also be incontinence, general weakness and inability to maintain body position. In addition, cancer patients usually have obvious pain before death due to the widespread spread of cancer cells, but they may not have obvious moaning and other manifestations due to their unconsciousness. For example, liver cancer patients may have severe jaundice and ascites before death; patients with esophageal cancer and lung cancer may have more obvious signs of breathing difficulties before death, but these signs may not necessarily be present because most patients have undergone different treatments.
