Early after intracardiac surgery, 43 patients were studied on pressure curve and hemodynamic-and-respiratory graph (HRG). The radial arterial pressure curves were putted into 4 groups: catacrotic, dicrotic, bisferious and plateau group.
The HRG was a radially arranged graph of the next 8 items: cardiac index, stroke index, total systemic peripheral resistance, ejection time, systemic pressure, Pco2, pH and Po2, in clockwise order.
The HRG were putted into 4 groups: 1st group was good type, having about regular octagon. 2nd groups was hemodynamic poor type, having a spike on right side. 3rd group was respiratory poor type, having a spike on left side. 4th group was both poor type, having both spikes.
In most of the catacrotic wave patients, the HRG were good type. In most dicrotic wave patients, the HRG were hemodynamic poor type and/or respiratory poor type. In most of the bisferious wave and plateau wave patients who manifested low cardiac output syndrome, the HRG were hemodynamic poor type and/or both poor type.
