Study Notes
Intra-Aortic Balloon Pump (IABP)
- A mechanical circulatory support device used for temporary cardiac support
- A catheter with a balloon (30-40mL) is inserted into the aorta through the femoral artery
- The balloon inflates during diastole, improving blood flow to coronary and renal arteries
- The balloon deflates before systole, decreasing the cardiac workload
- Inflation/deflation is triggered by the ECG pattern
- A 1:1 ratio provides the maximum support
- Weaning involves gradually decreasing the support as the heart recovers
Ventricular Assist Devices (VADs)
- Temporarily assist or fully take over cardiac function depending on device type
- Used for patients with AMI and/or cardiogenic shock with potential for recovery
- Also used as a bridge to heart transplantation
- Helps the weak heart by giving it a chance to rest and recover
- Nursing care includes assessing haemodynamic status and monitoring for complications
- VADs carry a high risk of infection, requiring strict aseptic technique for catheter handling and dressing changes
- Pneumonia is a significant complication due to limited mobility
- VAD mechanical failure is a life-threatening event
Cardiac Rehabilitation
- An interdisciplinary program for patients recovering from AMI, heart surgeries, and percutaneous coronary interventions
- Focuses on promoting recovery, maximizing functional performance, and developing self-management skills
