WebSep 25, 2013 · The rate of induction is more rapid in infants and children than adults and corresponds to a more rapid increase in alveolar towards inspired anaesthetic partial pressure. This has been attributed to a larger ratio of alveolar ventilation to functional residual capacity, increased cardiac output, and greater delivery of cardiac output to … WebThis condition is the narrowing of the aorta close to the ductus arteriosus insertion site. This leads to creater upper extremity perfusion and a decreased lower extremity perfusion. This CHD frequently occurs with other heart defects.
