Patients with tuberculosis have a range of symptoms of death, from a state of persistent hypothermia to a persistent state of high fever that does not subside; there may be marked respiratory distress, and after aggravation, hypoxemia and hypercapnia may occur, leading to respiratory failure, manifested as shortness of breath, wheezing, accompanied by lethargy, coma, chilled limbs, pale face, and hypotensive shock. In more severe cases, it can lead to multi-organ failure, manifested by hematuria, proteinuria, palpitations, chest tightness, and gradual slowing of the heart rate, leading to bradycardia until the heart stops beating, heart sounds disappear, and the pulse rate weakens until it disappears. At this time, the metabolism of the respiratory and circulatory systems completely stops, the vital signs disappear, and life ends.
