Arterial blood pressure during CPR; During surgery to establish femoral vascular access for the CPB, short coordinated pauses in chest compressions were needed. The picture shows the monitor shortly after such a break. Arterial pressure waves (red) from the restarted CPR are seen. The red numbers are the CPR induced arterial pressures systolic/diastolic (mean). The patient is asystolic or in fine ventricular fibrillation.
