Spring 23' Med Term quiz 4 Flashcards
Diastole
Heart relaxation (Bottom number of BP)
Systole
Heart contraction (Top number of BP)
Isometric
All 4 valves are closed and the ventricles relax
Murmur
turbulent, abnormal, blood flow through the heart
Cardiac output
The amount of blood pumped thought out the body (through the left side of the heart) in one minute
SV X HR = Cardiac output
Preload
is volume – it is the venous return that builds during diastole.
Afterload
Is pressure – it is the opposing pressure the ventricle must generate to open the aortic valve against the higher aortic pressure
Dysrhythmias
abnormal heart rhythm
Edema
swelling.
It is dependent when caused by heart failure
Bradycardia
Abnormally slow heart rate
<60 bpm
Tachycardia
Abnormally fast heart rate
>100 bpm
Palpitation
abnormally hard, fast or irregular heart beats
Erb’s Point
third intercostal space on the left sternal boarder
A good location to listen for S2 sounds
Closer of the semilunar valve
Listening for murmurs of the semilunar valves
Mitral Valve
Left AV valve
Pulmonic Valve
Right semilunar valve
Tricuspid Valve
Right AV valve
Ischemia
a deficient supply of oxygenated arterial blood to a tissue caused by obstruction of a blood vessel
Capacitance vessels
veins
Because of their ability to stretch
Incompetent valves
wherein the lumen (diameter) is so wise, that the valve cusps cannot approximate (close entirely)
Arteriosclerosis
blood vessels that have grown more rigid with age
Allen test
is used to evaluate the adequacy of collateral circulation before cannulating the radial artery
Aneurysm
A sac formed by dilation in the artery wall. Atherosclerosis weakens the middle layer of the vessel walls.
Claudication
pain caused by too little blood flow
Lymphedema
An accumulation of protein-rich fluid in the interstitial spaces of the arm following breast surgery or treatment
