NIBP - Applied

Question 1

If the forearm is below heart level, a
false _______ in pressure may occur

Answer 1

elevation

due to increased hydrostatic forces.

Question 2

Cuff width should be approximately
____% of the limb’s circumference.

Answer 2

40 %

Question 3

The length of the cuff is typically ____ times the width and
is not as critical to the accuracy of the measurement
as is the width.

Answer 3

2

Question 4

what is the most common technique for NIBP by machine?

Answer 4

oscillometric

Question 5

What 3 parameters does the NIBP measure? which is most accurate

Answer 5

systolic

diastolic (most accurate on Dinamap machine)

Mean (most accurate)

Question 6

What exactly is systolic pressure measuring?

Answer 6

Appropriately used to estimate vascular wall tension or stress in the case of new vascular anastomoses, vascular suture lines and aneurysms

Question 7

What exactly is diastolic pressure measuring

Answer 7

Used clinically to describe the driving pressure for blood flow to the left ventricle. The majority of blood flow to the left ventricle occurs during diastole

Question 8

what is a concern with oscillometry ?

Answer 8

oscillometry tends to overestimate b/p when hypotensive

and underestimate b/p when hypertensive

Question 9

How will a cuff that is too small effect the b/p reading?

Answer 9

falsely high b/p reading

I thought Biggs said today it would be low becuase it wouldn’t have to inflate to as high of a pressure to get the same oscillometric reading……

Question 10

how will a cuff that is too large effect the b/p reading

Answer 10

falsely low b/p reading

I thought Biggs said today it would be high becuase it would have to inflate to a higher pressure to get the same oscillometric reading……

Question 11

what type of sounds are ausculated when manually taking a NIBP

Answer 11

korotkoff’s sounds

Question 12

when a patient is lying flat arms at side, where will the b/p be slightly higher (i.e. 10 pnts on systolic).

A) the reading from upper arm

or

B) the reading from the lower leg

Answer 12

B) reading from the lower leg

Question 13

When a person is standing where is the blood pressure the highest? the lowest?

A) the bicep of a raised arm

B) the bicep of an arm hanging to side

C) the ankle

Answer 13

Highest = C) the ankle

lowest = A) the bicep of a raised arm

Question 14

what arrhythmia presents a problem for NIBP devices

Answer 14

Atrial Fibrilation

Note: the text mentions palpitations so this would include frequent PVCs and frequent PACs

Question 15

contraindications to NIBP

Answer 15

burns

av fistulas

iv in that extremety
