blood pressure Flashcards
generate an appropriate amount of intravascular pressure to ensure tissue perfusion
principle function of the cardiovascular system
the measurement of force applied to artery walls
blood pressure
refers only to arterial blood pressure
blood pressure
measures the pressure within veins
central venous pressure CVP
has the strongest correlation with body fluid volume
central venous pressure
what allows us to assess how well blood is returning to the heart and the hearts ability to recieve and pump blood
CVP
blood pressure too low
hypotension
what indicates inadequate organ perfusion
hypotension
what can be caused by drugs, vasodilation, toxins, shock, and severe dehydration
low BP
blood pressure is too high
hypertension
sensory nerve trauma that stimulates pressure change
barotrauma
what can cause over perfused or barotrauma in organs
high BP
what is usually due to kidney disease, hyperthyroidism, metabolic changes
high BP
what must be considered when evaluating a patients blood pressure
species, gender, and age
high risk high blood pressure that indicates intervention of drugs or antihypertensive agents
180/120mm Hg
moderately risk high blood pressure that indicates intervention should be considered due to risk of organ injury
150/95mm Hg
moderate risk low blood pressure that indicates intervention should be considered
100/60mm Hg
when can reduced organ perfusion occur
100/60mm Hg
high risk low blood pressure that mandates intervention with IV fluids and reduce anesthetics
70/40mm Hg
dog and cat normal systolic plood pressure
90/160mm Hg
dog and cat normal diastolic blood pressure
50/90mm Hg
normal awake mean arterial pressure
85-120mm Hg
normal anesthetized mean arterial pressure
70-90mm Hg
what is the most important measurement during anesthesia
MAP
average pressure through cardiac cycle
mean arterial pressure
what is the best indicator of blood perfusion
MAP
how do you calculate MAP
diastolic pressure+[(systolic pressure-diastolic pressure)/3]
