  • Front
  • Back
preload
amount of blood returning to the heart from both venous and pulmonary systems
afterload
the resistance against which the heart must pump
hypertension (HTN)
systolic >135
diastolic > 85
orthostatic hypotension
BP is not adequately maintained when moving from lying or sitting to standing
mean arterial pressure
[(2 x diastolic)+systolic] / 3]
periferal vascular resistance
resistance of cardiac flow through the vascular system
cardiac output
heart rate * stroke volume
stroke volume
amount of blood pumped by the left ventricle of the heart in one contraction
angina pectoris
insufficient oxygen supply to cardiac tissue
systole
contraction and emptying of atria and ventricles
diastole
relaxation and filling of atria and ventricles
hemodynamics
the hydrolic performance of the circulatory system
shock
whole body response to poor tissue oxygenation
hypovolemic shock
insufficient circulating blood causes mean arterial pressure to fall so full body's oxygen needs are not met
cardiogenic shock
cardiac output is insufficient to meet full body's need of oxygen
congestive heart failure
(CHF) insufficient left-sided or ventricular output
coronary artery disease
(CAD) broad definition of arterial afflictions... angina pectoris, acute coronary syndromes
cerebrovascular accident
stroke - disruption of blood supply to brain
transient ischemic attack
'silent stroke' effects lasting less than 24 hours
perfusion
extent of supply of oxygen to tissues
tissue perfusion
extent of supply of oxygen to tissues
activity intolerance
inability to participate in activity (motion)
arrhythmia
abnormal rhythms of cardiac eletrical pulses
thrombus
blood clot
embolus
wandering blood clot
