relationship between cardiac Blood Pressure
output and peripheral
resistance
BP is dependent on blood volume, velocity, vessel elasticity
maximum pressure on arteries systolic- ejection
during ventricular contraction
minimum pressure on arteries diastolic
during ventriular relaxation
volume of blood pumped by cardiac output
the heart during one minute
difference between systolic and pulse pressure
diastolic pressure. usually 30
age, gender (female lower than males until after puberty and
then increase after menapause
2x higher in african americans
emotions
factors affecting BP pain
caffeine and smoking
weight (obese have increase)
medications
early in the morning is low, afternoon is high
which sounds are heard from 2nd, 3rd, 4th
Korokoff sounds
no heard sound in which 5th during diastolic
Korokoff sounds?
, arm above level of heart
cuff too narrow or wide
common errors in BP deflating too slowly
measurement reinflating cuff without completely deflating
not waiting 1-2 min before repeat
pressing diaphragm too firmy on brachial artery (false low)
Prehypertensive 120-139/80-89
Stage 1 HTN 140-159/90-99
Stage 2 HTN >160/>100
palpate brachial artery inflate cuff til you can't feel the pulse,
how to find a palpable systolic
then 20 mm higher, release at 2-3 mmHG until you feel the pulse

low in morning higher in afternoon
variations of temp
exercise increases
stress increases temp
normal oral temp 97.7F-99.5F
when should you delay taking ingesting hot or cold liquids wait 15-30 min
temp?
tympanic temp normal 98.2-100F
temp temp, less than 3 pull _____? down
temp temp, over 3 pull____? up
axillary temp normal 96.7-98.5
axillary common site in what children and infants
population?
rectal normal temp 98.7-100.5
rectal more common in what comatose and seizing patients
population?
temporal temp normal 98.7-100.5
which is the safest quickest and temporal temp
most convenient way to take
temp?
60-70ml of blood enters aorta stroke volume
with each ventricular
contraction
adult normal pulse 60 to 100
newborn normal pulse 120-170
