  • Abstract
  • Look Inside

The capillary blood PO2 was determined for sam-ples, simultaneously drawn from the upper and the lower extremities of 29 patients with CHD. The PO2 difference between the upper and the lower extremities was 0.1-53.4 mmHg (median : 14.4 mmHg) for 9 patients with Interruption/Co-arctation of the aorta, and 0.2-11.2 mmHg (medi-an : 2.9 mmHg) for the other CHD 20 patients.

In the former group, when heart failure develop-ed, the PO2 difference decreased to 0.6-9.8 mmHg, due to the reduced O2 saturation in the upper ex-tremities. Measurement of the capillary blood PO2 in CHD patients is believed to be useful in detecting the pre-sence of Interruption/Coarctation of the aorta and to predict the exacerbation of the circulatory con-dition of such patients.
