As a respiratory therapist, I have never work with intra-aortic balloon pumps. My understanding of IABP is textbook knowledge, not personal experience. Intra-aortic Balloon Pump(IABP) or Intra-aortic Ballon Counterpulsation (IABC) is a mechanical assist device that that will benefit patients with a life-threating illness such as cardiogenic shock, cardiac defects, and unstable angina (Darovic, 2002). The IABP will reduce the resistance to the left ventricular ejection and improve coronary perfusion as well as systemic blood flow (Darovic, 2002). During diastole, the balloon inflates to increase diastolic pressure higher than systole pressure while displacing blood volume equivalent to its inflation volume (Darovic, 2002). IABP will enhance

Pfuecke and his associate performed a study to determine differences relating to IABP therapy with decreased cerebral blood flow and left ventricular ejection fraction(LVEF). The goal of treatment after an acute ischemic stroke is to improve cerebral blood flow (CBF) in ischemic brain tissue (Pfuecke et al., 2014). IABP counterpulsation in the setting of cardiogenic shock can decrease left ventricular afterload and increase coronary blood flow(Pfluecke, 2014). The study divided 36 patients into two groups according to their left ventricular ejection fraction (LVEF): Group 1 LVEF>30% and Group 2 LVEF < 30% showed a significantly higher increased cerebral blood flow compared to the patients with an LVEF >30% (Pfuecke et al., 2014).
1. How does IABP help with coronary perfusion?
2. What is the limitation of this study?
