| These things are built into our system to help the body compensate for changes and maintain cardiac output | Compensatory mechanisms |
| Compensatory mechanisms, designed to help maintain cardiac output, can also lead to this, creating a cycle that leads to more problems | Heart Failure |
| Because of increased blood flow to the heart to increase cardiac output, blood flow is decreased to what organ | Kidneys |
| What causes compensatory mechanisms to begin (associate this wth cardiac patients)? | CAD, MI, Cardiomyopathy, valve problems, HTN, Ischemia, etc |
| This is the major cause of LSHF | HTN because of peripheral vascular resistance (pressure in the aorta and arteries that tells the LV how much force is needed to eject blood) |
| Signs of LSHF are of this nature. | Pulmonary |
| The major cause of RSHF is this | LSHF |
| Signs of RSHF are of this nature | Systemic (like edema of extremities and organs) |
| Hemodynamic monitoring with a Swanz-Ganz cath measures this | Right-sided heart pressures directly and left-sided heart pressures indirectly |
| Why is a pacemaker put in a client with severe heart failure? | With ventricular failure, one ventricle falls behind slightly in contractions - pacing them will ensure they beat together |
| What is the purpose of an intra-aortic balloon pump (IABP)? | To increase blood flow to the coronary arteries during ventricular diastole to ensure the myocardium is oxygenated |
| Why is a pacer needed after a cardiomyoplasty? | Skeletal muscle is used as the transplanted muscle and it has no ability to create its own impulse. |
