Thoracolumbar

Question 3

Parasympathetic system affects..

Answer 3

Craniosacral

Question 4

Reference range for CI?

Answer 5

2-4 L/min/m2

Question 6

SBP

Answer 6

Pressure required to perfuse organs and tissues

Question 7

DBP

Answer 7

Pressure required to bring blood back to the heart and fill the venticles

Question 8

HRV

Answer 8

Heart rate variability; A healthier heart has the ability to change and adapt when needed.

Question 9
