Intra-Aortic Balloon Pump
Key Terms
- Counterpulsation
- increases blood flow to coronaries, lowers afterload on heart
- when aortic valve closes, baloon inflates to force blood back towards beart and down coronary arteries
- when aortic vale is open and heart squeezes, baloon rapidly deflates causing a suction which drops afterload
- Afterload
- the pressure of the arteries, capillaries, snd veins the heart
pushes against to generate a blood pressure
- measured as SVR on systemic circulation and PVR on pulmonary side
- Systemic Vascular Resistance (SVR):
- Normal range: 800–1,200 dynes·sec/cm⁵.
- Pulmonary Vascular Resistance (PVR)
- Normal range: 100–250 dynes·sec/cm⁵
Indications
Contraindications
- Absolute
- Aortic Insufficiency because the valve must stay closed in orfer for blood to flow down coronaries
- Aortic Dissection
Adverse Events
- Early Inflation
- Late Inflation
- Early Deflation
- Late Deflation
- Thrombosis
- Embolism
- Balloon rupture
- Hemorrhage
General Procedure
- Prepare the patient and obtain informed consent.
- Position the patient supine and prep the insertion site (usually the femoral artery).
- Administer local anesthesia at the insertion site.
- Insert a sheath into the femoral artery using the Seldinger technique.
- Advance the guidewire through the sheath and into the aorta under fluoroscopic guidance.
- Thread the intra-aortic balloon catheter over the guidewire and advance it to the desired position (tip should be just distal to the left subclavian artery).
- Confirm the position of the balloon using fluoroscopy or chest X-ray.
- Connect the balloon catheter to the IABP console and initiate counterpulsation.
- Monitor the patient’s hemodynamic status and adjust the IABP settings as needed.
- Secure the catheter and sheath in place and apply a sterile dressing to the insertion site.
