Pulse Flashcards
a wave of blood created by contraction of left ventricle of the hearts
pulse
represents the stroke volume output or the amount of blood that enters the arteries with each ventricular contractions
pulse
ability to contract and expand
compliance of the arteries
the volume of blood pumped into the arteries by the heart and equals the result of the stroke volume (SV) times the heart rate (HR) per minute
cardiac output
when an adult is resting, the hearts pumps about ____ of blood each minute
5 liters of blood
pulse located away from the heart, for ex. in the foot or wrist
peripheral pulse
is a central pulse; located at the apex of the heart.
apical pulse
apical pulse, also referred to as the
point of maximal impulse (PMI)
factors affecting the pulse
age, sex, exercise, fever, medications, hypovolemia or dehydration , stress, position, pathology
as age increases, the average pulse rate gradually….
decreases
after puberty, the average male’s pulse is slightly ___ than the female’w
lower
loss of fluid from the vascular system, increases the pulse rate
hypovolemia or dehydration
pulse is commonly measured in nine sites
temporal
carotid
apical
brachial
radial
femoral
popliteal
posterior tibial
dorsalis pedis
where the temporal artery passes over the temporal bone of the head
temporal
readily accessible
radial
used when the radial pulse is not accessible
temporal
used during cardiac arrest or shock in adults; used to determine circulation to the brain
carotid
routinely used for infants and childrens up to 3 years of age; used to determine discrepancies of radial pulse; used in conjunction in some mediations
apical
used to measure blood pressure; used during cardiac arrest for infants
brachial
used in cases of cardiac arrest or shock; used to determine circulation to a leg
femoral
used to determine circulation to the lower leg
popliteal
use.to determine circulation to the foot
posterior tibial and dorsalis pedis
most commonly used in adults.
radial site
