The device gets smaller when your heart pumps so blood can flow out to the rest of your body. Then it gets bigger when your heart relaxes to keep more blood in your heart. Your doctor may recommend an IABP if your heart isn’t getting enough blood or isn’t sending enough out to the rest of your body. This condition is called cardiogenic shock.
Why would I need An IABP device?
An IABP is attached to a tube called a catheter. The balloon is inserted into your aorta with the help of an X-ray camera. The aorta is the very large artery leaving the heart. This procedure is done through a small cut on the inside of the upper leg. The balloon pump catheter is inserted into an artery in the leg and then guided into the aorta.
How is An IABP procedure performed?
The device gets smaller when your heart pumps so blood can flow out to the rest of your body. Then it gets bigger when your heart relaxes to keep more blood in your heart. Your doctor may recommend an IABP if your heart isn’t getting enough blood or isn’t sending enough out to the rest of your body.
What does it mean when your IABP gets bigger?
What You Should Know. An IABP is attached to a tube called a catheter. Your doctor will put the catheter and balloon into an artery in one of your legs and use an X-ray camera to move it up to your aorta. The device is hooked up to a machine that tells the balloon when to get bigger and when to get smaller.
What should I know about An IABP catheter?
What is the primary goal of IABP?
The primary goal of IABP treatment is to improve the ventricular performance of the failing heart by facilitating an increase in myocardial oxygen supply and a decrease in myocardial oxygen demand.
How do IABP work?
The intra-aortic balloon pump (IABP) reduces the workload on your heart, allowing your heart to pump more blood. The IABP is placed inside your aorta, the artery that takes blood from the heart to the rest of the body. The balloon on the end of the catheter inflates and deflates with the rhythm of your heart.
What are the indications for IABP?
IndicationsAcute congestive heart failure exacerbation with hypotension.As prophylaxis or adjunct treatment in high risk percutaneous coronary intervention.Myocardial infarction with decreased left ventricular function leading to hypotension.More items...•
How does IABP reduce afterload?
The intra-aortic balloon, by inflating during diastole, displaces blood volume from the thoracic aorta. In systole, as the balloon rapidly deflates, this creates a dead space, effectively reducing afterload for myocardial ejection and improving forward flow from the left ventricle.
Does IABP increase blood pressure?
The IABP increases diastolic blood pressure, decreases afterload, decreases myocardial oxygen consumption, increases coronary artery perfusion, and modestly enhances cardiac output. The IABP also provides modest ventricular unloading while also increasing mean arterial pressure and coronary blood flow.
How much does IABP increase cardiac output?
The increase in cardiac output detected with intraaortic balloon treatment is between 0.5 and 1.0 l per minute.
Can you do CPR with an IABP?
IABP during CPR: The IABP does not need to be disconnected during defibrillation (but staff should be clear of the IABP and console). Set the IABP to pressure trigger as an arterial waveform should be generated during CPR.
How long can a balloon pump stay in?
How long can an intra-aortic balloon pump stay in? An intra-aortic balloon pump usually only stays in place for a few days. However, your provider may keep it in place for up to 30 days, or sometimes longer. An intra-aortic balloon pump is a device that controls blood flow through your heart.
What is a contraindication of an intra-aortic balloon pump?
Contraindications to IABP include severe peripheral vascular disease as well as aortic regurgitation, dissection, or aneurysm. The potential benefits of IABP must be weighed against its possible complications (bleeding, systemic thromboembolism, limb ischemia, and, rarely, death).
What gas is used in a balloon pump?
HeliumHelium is used to inflate the balloon as its low density means there is little turbulent flow, so the balloon can inflate quickly and deflate slowly. It is also relatively benign and eliminated quickly if there is a leak or rupture in the balloon.
How far is the IABP inserted?
The appropriate performance of the IABP is dependent on proper position (1,2). Ideally, the tip of the balloon should be positioned 2–3 cm distal to the origin of the left subclavian artery (LSCA) (1,3).
Does IABP increase ejection fraction?
With IABP, the ejection fraction increased by 0 +/- 0.5% in group I and 5.8 +/- 1.7% in group II (p = 0.004); the regional ejection fraction increased by 0.1 +/- 0.9% in group I and 10.3 +/- 2.1% in group II (p = 0.0004); the systolic chordal shortening increased by 1.1 +/- 0.6% in group I and 6.5 +/- 1.1% in group II ...
Can you do CPR with an IABP?
IABP during CPR: The IABP does not need to be disconnected during defibrillation (but staff should be clear of the IABP and console). Set the IABP to pressure trigger as an arterial waveform should be generated during CPR.
When does a balloon pump inflate?
The balloon is set to inflate when the heart relaxes. It pushes blood flow back toward the coronary arteries. They may not have been receiving enough blood without the pump. When the heart contracts, the balloon deflates.
How long can a balloon pump stay in?
How long can an intra-aortic balloon pump stay in? An intra-aortic balloon pump usually only stays in place for a few days. However, your provider may keep it in place for up to 30 days, or sometimes longer. An intra-aortic balloon pump is a device that controls blood flow through your heart.
When should IABP inflation occur?
diastoleIn normal inflation-deflation timing, balloon inflation occurs at the onset of diastole, after aortic valve closure; deflation occurs during isovolumetric contraction, just before the aortic valve opens.
Why do you need an IABP?
Your doctor may recommend an IABP if your heart isn’t getting enough blood or isn’t sending enough out to the rest of your body. This condition is called cardiogenic shock. It can happen after a heart attack, when your heart is weak, or because of another heart problem like:
How to make sure IABP doesn't move?
You’ll need to stay in bed and keep your leg straight to make sure the device doesn’t move. Your doctor and nurses will keep a close eye on you to make sure the IABP is working the way it should.
How long does IABP stay in place?
An IABP also might be used to help you recover from surgery to reopen or bypass a blocked artery near your heart. It’s only in place for a short time, typically a few days, while you’re in the hospital.
What is an intra aortic balloon pump?
An intra-aortic balloon pump, or IABP, is a long, skinny balloon that controls the flow of blood through your largest blood vessel, the aorta. The device gets smaller when your heart pumps so blood can flow out to the rest of your body. Then it gets bigger when your heart relaxes to keep more blood ...
What is the IABP?
The IABP consists of a thin, flexible tube called a catheter. Attached to the tip of the catheter, is a long balloon. This is called an intra-aortic balloon or IAB. The other end of the catheter is attached to a machine (computer console). This machine has a mechanism for inflating and deflating the balloon at the proper time when the heartbeats.
How is IABP done?
The aorta is the very large artery leaving the heart. This procedure is done through a small cut on the inside of the upper leg. The balloon pump catheter is inserted into an artery in the leg and then guided into the aorta.
What is an intra aortic balloon pump?
Intra-aortic balloon counterpulsation or intra-aortic balloon pump (IABP) is a type of therapeutic device which helps the heart to pump more blood.
Why does IABP inflate?
It inflates when the heart relaxes to keep more blood in the heart. IABP allows blood to flow more easily into the coronary arteries (arteries in the outer walls of the heart). IABP also helps your heart pump more blood with each contraction. IABP is a short-term treatment.
When is IABP performed?
IABP is performed when the heart isn’t getting enough blood or isn’t pumping out to the rest of the body. It can be performed after the following heart problems: An IABP may be used to help recover from surgery to reopen or bypass a blocked artery near the heart.
What are the complications of Intra-aortic Balloon pump?
Though rare, as with any procedure, there’s a risk of complications, such as:
How does IABP work?
As the heart relaxes, the balloon inflates. It forces the blood back into the coronary arteries. These arteries can’t get adequate blood without a pump. When the heart shrinks, the balloon also shrinks. This shrinkage generates additional room in the aorta, which allows the heart to pump more blood. This process will reduce the stress on your heart. The pump will continue to expand and contract until it eliminates.
Where do you put the IABP catheter?
Next, you or your doctor will require to insert a balloon pump catheter into the leg artery. After this, you need to bring it to your aorta. After this, the IABP will start working.
What is an Intra-aortic Balloon Pump?
An intra-aortic balloon pump (IABP) is a mechanical machine that rises the oxygen (O2) perfusion to the heart and the heart’s muscle and also increases the blood flow (cardiac output). Increased cardiac output boosts the flow of the coronary blood, which increases the supply of O2 to the heart.
What are the risks for intra-aortic balloon pump therapy?
Treatment with IABP is beneficial. Sometimes it even saves lives. But it also has some risks that are given below:
How do I prepare for intra-aortic balloon pump treatment?
Before the treatment, you must talk with your healthcare provider. Your healthcare provider will provide detailed directions about your treatment.
Why does the balloon pump inflate during diastole?
During the working, the intra-aortic balloon pump balloon expands and depresses due to the reverse pulsation process. In simple words, it inflates during diastole and depresses aggressively during systole. With the help of the vacuum effect, the systolic deflation reduces the afterload and indirectly improves the anterior blood flow to the heart. The pump inflates during the diastole process and boosts the coronary arteries’ blood flow through the retrograde blood flow. Together, these processes (systolic and diastole) reduce myocardial O2 need and increase myocardial O2 (oxygen) delivery.
Why is a transducer required for continuous blood pressure monitoring?
A transducer is compulsory for continuous blood pressure monitoring because the IABP uses a double notch in the aortic blood pressure curve to measure the time of expansion and contraction of the balloon.
What is the purpose of IABP?
The basic premise behind the IABP is to increase aortic diastolic pressure to improve coronary perfusion. The balloon inflates rapidly with helium (less dense gas creates less turbulent flow and faster inflation/deflation) during diastole and creates an “ augmented diastolic pressure ” higher than normal. It is this diastolic pressure that is a primary determinant in coronary perfusion pressure. With the onset of systole, the balloon deflates, dropping the afterload and improving cardiac output. However, because of this constant mechanical agitation within the aorta, absolute contraindications include severe aortic insufficiency, aortic dissection, and severe peripheral vascular disease. In general, the sicker the left ventricle, the less the IABP can actually help compared to devices like the Impella.
Where is the IABP located?
Therefore, when properly positioned, the IABP occupies the entire descending thoracic aorta and much of the suprarenal abdominal aorta. Although fluoroscopy/echocardiography can help guide placement, they are not absolutely necessary in emergent situations.
What is an intra aortic balloon pump?
The intra-aortic balloon pump ( IABP) is a form of mechanical circulatory support used in cardiogenic shock, facilitating separation from cardiopulmonary bypass, percutaneous coronary interventions, unstable angina, and thrombolytic therapy following myocardial infarction. The device is introduced from the femoral artery and guided into the aorta until its tip is distal to the left subclavian artery takeoff from the aortic arch. Therefore, when properly positioned, the IABP occupies the entire descending thoracic aorta and much of the suprarenal abdominal aorta. Although fluoroscopy/echocardiography can help guide placement, they are not necessary for emergent situations.
Is IABP firing during systole?
It’s imperative to check that the IABP is firing appropriately relative to the cardiac cycle. Having the balloon inflated during systole will cause a significant impediment to forward flow, and having it deflated during diastole defeats the purpose. These are just the basics of this useful counterpulsation device.
How does IABP affect the heart?
The IABP assists the heart indirectly by decreasing the afterload and augments diastolic aortic pressure with subsequent enhancement in diastolic blood flow resulting in better perfusion of the peripheral organ as well as a possible improvement in the coronary blood flow. The intra-aortic balloon inflates during diastole synchronously with aortic valve closure and the appearance of a dicrotic notch resulting in the displacement of blood from the thoracic aorta into the peripheral circulation that is followed by rapid deflation before the onset of systole phase of the cardiac cycle. Theoretically, this results in improved diastolic pressure and reduced systolic aortic pressure by reducing the afterload, which subsequently results in decreased left ventricle wall stress reducing the myocardial oxygen demand. These hemodynamic changes improve the cardiac output by increasing stroke volume, particularly in patients with reduced left ventricular function.
How is an IABP catheter inserted?
The IABP catheter is inserted and advanced over the 0.018" guidewire to the proper positioning of the balloon in the aorta. The location of the intra-aortic balloon with its tip lying distal to the left subclavian artery and the proximal portion ending above the origin of renal arteries is considered as the ‘safe zone,’ and the confirmation of position can be by chest x-ray or fluoroscopy. Following guidewire removal, and the central lumen of the catheter is flushed and connected to the transducer to measure intra-aortic pressure. The IABP catheter gets connected to the extender catheter, which then connects to the IABP console. [14]
What is included in an intra aortic balloon pump kit?
Intra-aortic balloon pump kit: That includes an intra-aortic balloon pump system with an IABP catheter, arterial dilator, a guidewire, angiographic needle.
Does IABP help with ventricular failure?
IABP use may also help patients with acute right ventricular failure by reducing the right ventricular afterload by decreasing pulmonary artery pressure and left ventricular end-systolic and end-diastolic pressures and, as a result, improves the cardiac output. [5][6]
Does IABP increase aortic stiffness?
Stefanadis et al. demonstrated a 30% increase in aortic distensibility with IABP, thereby reducing the aortic stiffness constant, resulting in a 24% increase in cardiac index and a 31% reduction in myocardial oxygen demand.[3] In patients with systolic heart failure, IABP improves ventriculoarterial coupling ratio and consequently enhances stroke volume by reducing peripheral arterial elasticity without affecting the left ventricular end-systolic elastance. In these patients with low output, a reduction of end-systolic pressures, end-diastolic pressure, and volume of the left ventricle with IABP result in a leftward shift of pressure-volume loop with a reduced pressure-volume loop area suggesting a decrease myocardial oxygen demand. [4]
Do you need informed consent before IABP?
Prior to the insertion of IABP, informed consent is necessary with a clear explanation of the risks and benefits of IABP insertion.
Do you have to flex your leg before IABP?
These instructions include not to flex the leg if femoral artery access of that leg was the entry point for IABP insertion and inability to walk till the device is in place in case of femoral artery access used for device insertion.
