This recording belongs to a patient on IABP (Intra aortic balloon pump) kept in a 1:1 assist ratio (one balloon inflation for every cardiac cycle). The IABP assisted waveform shows augmented diastolic pressure. The main function of IABP is to improve coronary circulation by augmenting the diastolic blood pressure by inflation of the balloon during diastole, it also decreases the after-load by active deflation during systole and it's the reason for decrease in systolic pressure.
