Intergrated Cardio Responses Part 1 Flashcards
What is any condition in which a depressed cardiac contractility limits the ability of the heart to deliver an adequate cardiac output?
Heart failure
What are these potential causes for:
Ischemia of heart muscle
Myocarditis
Drug effects
Electrolyte imbalances
Heart failure
The compensation by starlings mechanisms does not return ________ volume to its normal contractility remains severely depressed
Stroke
When arterial pulse pressure is depressed then:
Barorecpeor activity is decreased
Sympathetic is _________
Parasympathetic is decreased
Increased
Heart failure leads to exercise intolerance because the patient has limited ____________ reserve
Sympathetic
Left ventricular failure: pulmonary ______ develops, hypoxemia, and pleural effusion
Edema
Right ventricular failure: Edema is dependent in the ___________ and abdomen
Extremities
Heart failure also leads to:
Persistent __________ in blood volume- treated with diuretic drugs, and Decompensation
Increase
What % of hemorrhage can be fatal without compensation?
40
When hemorrhage occurs, blood is mainly lost from the blood reservoirs of the body, the ____
Veins
After compensation from hemorrhage by the arterial volume and baroreceptor reflexes, the
Mean arterial pressure decreases by __%
Stoke volume and cardiac output decrease by __%
10
20
Increases in arterial volume and baroreceptors increase ________ activity and decrease parasympathetic activity
Sympathetic
Adaptive feature of the blood sequestered in the ________ has higher than normal hematocrit, which helps offset fall in hematocrit that is a normal consequence of interstitial fluid reabsorption after hemorrhage
Spleen
Water reabsorption during the first - hours helped restore blood volume
3-4
Hemorrhage cases capillary hydrostatic pressure to fall below normal and ______ reabsorption of interstitial fluid back into the capillaries
