Fig. 1

Activated clotting time (ACT) and heparin concentration during cardiopulmonary bypass (CPB). ACT was measured with the Hemochron Jr. Signature+, and heparin concentration was measured by heparin-protamine titration test using Hemostasis Management System Plus. The dose of heparin was determined for maintaining ACT > 480 s with the Hemochron Jr. Signature+. Changes in ACT measured with different devices are shown below. ACT measured by the Hemochron 401 was not available after heparin administration because baseline ACT was markedly prolonged (308 s). n/a: not available
