|
describe the physiololgical basis for pulse
|
SA node fires impulse thru heart muscle to stimulate cardiac contraction. This pulse wave is 5X faster thru Aorta & 100 X faster thru small artories.
|
|
|
what is cardiac output?
|
one minute of blood pumped by heart like 5000 mL per min
|
|
|
discus oral, rectal, axillary temps
|
oral is 98.6
auxilary is 97.6 rectal (core) is 99.6 |
|
|
discuss heat process of body
|
hypothymilmus is thermostate
this creates vasodialation and vasoconstriction heat production is a byproduct of metabolism, both carboydrate and protein thyroid hormones affect BMR (basal metabolic rate) |
|
|
explain methods to encourage loss of heat
|
evaporation 600-900 mL a day from sweating
Diaphores ...head sweating Radiation...flush from running conduction...ice pack or bathing a patient convection...moist skin against moving air |
|
|
state 2 reasons to take a rectal or axillary
|
patient can't use the mouth
ng tube, mentally unable |
|
|
what are and where are all the pulse sites?
|
termperal
carotid apical brachial radial ulnar femoral pedial another one in lower leg |
|
|
describe what happens within the circulatory system to cause blood pressue
|
bp = pressure on wall of an artery by pulsing blood under pressure from the heart. BLOOD FLOWS B/C OF CHANGING PRESSURE.high to low.
|
|
|
how does age gender weight activity affect bp?
|
age goes up
weight goes up activity goes up |
