Cardiovascular System — Flashcards

Flashcard 81: _____ is a maneuver that is used to increase preload, afterload, and venous return

Answer: Rapid squatting

Flashcard 82: Primary hypertension is related to increased _____ and TPR

Answer: cardiac output

Flashcard 83: A(n) _____ in TPR causes a clockwise rotation of the vascular function curve

Answer: increase

Extra: An increase in Total Peripheral Resistance (TPR) increases the resistance to venous return, decreasing the slope of the vascular function (venous return) curve. This results in a clockwise rotation around the X-intercept (Mean Systemic Filling Pressure). Conversely, a decrease in TPR causes a counterclockwise rotation.

Flashcard 84: _____ rhinitis occurs due to parasympathetic overactivity which causes vasodilatation and congestion.

Answer: Vasomotor

Flashcard 85: Cerebral blood flow is autoregulated extremely well between arterial pressure limits of _____ and 140 mm Hg

Answer: 60

Flashcard 86: The second phase of Lewis' triple response is _____ which occurs due to arteriolar dilatation, secondary to axon reflex

Answer: flare

Flashcard 87: _____ is released from atrial myocytes in response to increased blood volume and atrial pressure

Answer: Atrial natriuretic peptide (ANP)

Flashcard 88: Increased _____ results in an increased width and increased height on a pressure-volume loop curve

Answer: contractility

Flashcard 89: Increased _____ results in a(n) decreased width and increased height on a pressure-volume loop curve

Answer: afterload

Flashcard 90: Type _____ respiratory failure is caused by hypoperfusion of respiratory muscles in patients with shock.

Answer: IV
