A similar process also involves the left side ; but the progressive and dangerous dilatation of the right side plays the chief role, and contributes mainly to the fatal exitus. The gradual asphyxia which so often supervenes during the terminal stage of illness is also complicated by a Circle. For it is characterised by shallow respirations which do little to aerate the blood, and thus lead to narcosis of the respiratory centre, still shallower respirations and death. This is indeed a merciful Circle which leads to a peaceful painless end. Atelectasis. Pulmonary atelectasis is frequently fatal in weakly or rickety infants, whose death gives rise to great consternation, since a trifling catarrh may suffice to start the pathological sequence.
