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. The gas used in t

Great post from @master_cardiology! ⠀ ⠀ 🔷🔷Intra-aortic balloon pump (IABP)🔷🔷⠀ is a mechanical device used in congestive heart failure that increases myocardial oxygen perfusion and indirectly increases cardiac output through afterload reduction. It consists of a cylindrical polyurethane balloon that sits in the aorta, approximately 2 centimeters (0.79 in) from the left subclavian artery. The balloon inflates and deflates via counter pulsation, meaning it actively deflates in systole and infl
