what does vagal stimulation cause

• hypotension

• bradycardia

• nausea

what is stroke volume

amount of blood pumped by LV with each contraction (70 mL/beat)

how is SV calculated

substracting End-Diastolic Volume (EDV) and End-Systolic Volume (ESV)

how to calculate cardiac output CO

SV x HR

how can the depth of a respiration be described

deep, shallow, or labored

systolic pressure

when arteries contract (pump blood)

diastolic pressure

arteries relaxiing, filling w blood

pulse pressure

difference between systolic and diastolic pressure

ex: 120 - 80 = 40 mmHg

can vital signs be delegated?

yes

if readings are abnormal what should you do first

asses equipment

what does pulse oximetry measure

amount of oxgygen bound w hemoglobin

is oxygen a medication?

yes

vasoconstriction vs vasodilation in thermoregulation

vasoconstriction —> reduce heat loss

vasodilation —> promote heat loss, why my face gets red

diff between pursed lip and deep breaths

• pursed lip - moves oxygen into lungs and CO2 out, keep airways open

• deep breaths - increase air in lower lungs

what 2 positions are best for respiration

• tripod
