superior and inferior cava
tricuspid valve
the right ventricle ejects the blood through _____ into the ____ during ventricle systole
pulmonic valve, pulmonary artery
blood enters the ______ system where it exchanges the CO2 for O2
pulmonary capillary
the oxygenated blood leaves the lungs via the ____ and returns to the ____
pulmonary veins, left atrium
the ____pumps blood into the systemic circulation through the ____ to supply all the tissues of the body with O2
left ventricle
aorta
from the systemic circulation, blood return to the heart through the
superior and inferior vena cava
blood pressure
force that drives blood through the circulatory system
blood pressure influenced by
cardiac output, total peripheral resistance
BP= pressure in an artery at
peak of LV systole (SBP) and diastole (DBP)
the 40-year risk for developing HTN is ____% for African Americans, ___% for hispanics __% for whites
93, 93, 86
HTN leads to increased risk for
CVD, angina, MI, heart failure, stroke, PAD
HTN is a major cause of
death and disability
HTN is associated with increased risk of
DM and kidney disease
risk for health related to CVD increases in a strong fashion with
increased BP
hypotension <___ SBP, <___ DBP
80, 60
normal BP
<120, <80
high-normal/elevated/pre-hypertensive BP
120-129, <80
stage 1 hypertension
130-139, 80-89
stage 2 hypertension
> 140, >90
hypertensive crisis
> 180, >120
BP cuff size important: bladder length ___%, width ___%
80, 40
if cuff is too short or too narrow, BP reading will be
erroneously high
if cuff is too wide or too long, BP will be
erroneously low
when a cuff is too small for the upper arm and a larger cuff is not available, or if the arm is so large or its shape cant accommodate a proper fitting cuff, BP should be obtained by
cuff placed on forearm with the auscultation over the radial artery in the wrist
