Term
| Complications with line in radial artery |
|
Definition
arterial dissection
trauma to nerves
hematoma
thrombus
decreased blood flow to the hand |
|
|
Term
|
Definition
-tricuspid and mitral valves open
-blood leaves the atria to the ventricles
-pressure in atria an ventricles equalizes at end of diastole |
|
|
Term
|
Definition
-pulmonic and aortic valves open
-blood rapidly ejected from the ventricles to pulmonary artery/aorta
-systolic pressures between the ventricle and artery equalize |
|
|
Term
|
Definition
| amount of blood ejected from each ventricle with each heart beat. |
|
|
Term
|
Definition
force or load on ventricle during diastole
volume
end diastolic volume |
|
|
Term
|
Definition
force or load on the heart during ejection systole
Pressure
inversely related to CO |
|
|
Term
|
Definition
-inotropic state of muscle fibers
-affects perfusion status
-helps determine the force of ventricular contraction |
|
|
Term
|
Definition

|
|
Term
|
Definition

|
|
Term
|
Definition
-Pulmonary artery wedge pressure
-left heart volume status
-norm 6-12

|
|
Term
|
Definition

-norm 70-100 |
|
|
Term
|
Definition

|
|
Term
| What would you give for a high contractility? |
|
Definition
Beta blockers
Ca channel blockers |
|
|
Term
|
Definition
-loss of intravascular volume and what is left is inadequate to fill vascular space
-decreased blood flow and tissue perfusion |
|
|
Term
|
Definition
-impaired ability of heart to pump blood
-due to left ventricular heart failure |
|
|
Term
| Intraaortic Balloon pumping |
|
Definition
-inflates during diastole to increase coronary artery flow (increase supply)
-deflates during systole to decrease afterload (decrease demand) |
|
|
Term
|
Definition
-implanted device used to partially/totally support patients with ventricular failure
-allows heart to heal
-gives time while waiting for heart transplant |
|
|
Term
|
Definition
severe allergic reaction
increased capillary permeability |
|
|
Term
|
Definition
| ineffective SNS that causes no nerve signals to transmit resulting in vasodilation |
|
