what is the etiology of hypovolemic shock?
Give this one a try later!
-inadequate circulation blood volume
-inadequate perfusion of tissues
-hemorrhage (most common)
-burns
-severe vomiting/diarrhea
-leakage of fluid into interstitial spaces
describe aortic regurgitation
Give this one a try later!
, -rheumatic fever, infections, marfan
-blood leaks from aorta back to left ventricle
-increased left ventricle pressure
-ventricular hypertrophy leads to ischemia and left sided heart failure
-left ventricular hypertrophy
-may lead to left sided HF
-C/O throbbing or pounding bc of large LV stroke volume-bounding pulse
-CP, fatigue, dyspnea, peripheral edema
diagnosis:
-echo
treatment:
-medications/surgery
what is chronic heart failure?
Give this one a try later!
-most common
-heart gradually weakens over a period of time
what are the mechanisms for cardiovascular regulation?
Give this one a try later!
, RAAS
-raises BP
-increases blood volume
in heart failure, the RAAS continually cycles and weakening the heart
increases resistance (afterload)
increased workload
ventricular remodeling weakens the heart
what are the clinical manifestations of neurogenic shock?
Give this one a try later!
-hypotension
-syncope with standing
-bradycardia
-decreased CO
what is the etiology/pathogenesis of anaphylactic shock?
Give this one a try later!
-extreme allergic reaction
-antigen/IGE antibody reaction
-vasoactive chemicals released
-shock occurs when peripheral dilation is massive
-causes "pseudo" hypovolemic shock
-onset of symptoms 2-30 min of exposure to antigen
