Term
| Failure of Left Heart pump |
|
Definition
1. left ventricle failure
2. backflow from lungs
3. pulmonary edema
4. increased pulmonary artery pressure
5. Cor pulmonale
decresed cardiac output to systemic organs
First sign: RESPIRATORY DISTRESS |
|
|
Term
|
Definition
1. right ventricle dilation and hypertrophy
2. increased pressure of Jugular veins
3. Increased central venous pressure
4. congestive hepatomegaly (liver)
5. ascities (kidneys)
6. pedal adema
decreased blood supply to entire body |
|
|
Term
| Cardiac outflow to organs |
|
Definition
| in parrallel so each organ gets blood depending on its metabolism. Liver and gut consume most O2. Flow can be adjusted to individual organs without affecting whole system. |
