What does augmentation mean on IABP?

What does augmentation mean on IABP?

a corresponding increase in myocardial blood flow and. oxygen supply. During IABP augmentation, the DPTI is. increased as the aortic diastolic blood pressure is increased. and the left ventricular diastolic pressure is decreased.

Why is IABP contraindicated in aortic stenosis?

Significant aortic regurgitation is considered a contraindication for the usage of an IABP, because inflation of the balloon during diastole increases the amount of blood regurgitating into the left ventricle.

What does Dicrotic notch signify?

The dicrotic notch, which is widely believed to represent the closure of the aortic valve, (but in fact…) The diastolic phase, which represents the run-off of blood into the peripheral circulation.

Why is helium used in IABP?

Helium is used to inflate the balloon as it is low density means there is little turbulent flow, so the balloon can inflate fast and deflate slowly. It is also relatively benign and eliminated quickly if there is a leak or rupture in the balloon.

How do I place an IABP?

In many cases, this procedure is done through a small cut on the inside of your upper leg. Your healthcare provider will insert the balloon pump catheter into an artery in your leg. He or she will then guide it to your aorta. From there, the IABP can start to do its work.

When should a balloon pump be removed?

Vigilance in monitoring this tubing is therefore paramount in the overall care of patients under IABP support. If blood is noted—it should prompt the removal of the balloon within 30 min, as the longer it is left after its rupture the drier the clot becomes and the less likely it is to extract at the bedside.

Why is IABP contraindicated in aortic aneurysm?

The use of an intraaortic balloon pump (IABP) for circulatory support in these patients is traditionally considered contraindicated because of concerns over extension of the residual dissection flap or aortic rupture.

What does whip in arterial line mean?

Resonance or whip causes falsely increased systolic readings and falsely decreased diastolic readings. It occurs when the system’s frequency of oscillation (i.e., heart rate) matches the system’s natural frequency of vibration causing whip in the signal.

What is IABP counterpulsation?

Overview. Intra-aortic balloon counterpulsation is a method of temporary mechanical circulatory support that attempts to create more favorable balance of myocardial oxygen supply and demand by using the concepts of systolic unloading and diastolic augmentation.
