Blood Pressure Monitoring

Question 1

Blood pressure is…

Answer 1

The driving force for blood flow (perfusion). It is req to move blood thru resistant capillary beds such as brain, kidneys, & lungs

Question 2

Systolic pressure is…

Answer 2

Arterial pressure generated during left ventricular contraction

Question 3

Diastolic pressure is…

Answer 3

Arterial pressure during ventricular relaxation

Question 4

Mean Arterial Pressure (MAP) is…

Answer 4

Calculation that evaluates perfusion pressure

Question 5

MAP = __/3 systolic + __/3 diastolic
MAP of ___mmHg is considered minimum for organ perfusion

Answer 5

1/3 systolic, 2/3 diastolic
Minimum 60mmHg

Question 6

Hypertension for extended periods can results in… (5)

Answer 6

1. Retinal hemorrhage/detachment
2. Kidney damage
3. Increased afterload for heart
4. Brain damage
5. Increased risk for emboli

Question 7

> ___mmHg systolic or >___mmHg diastolic is hypertension in cats & dogs

Answer 7

> 150mmHg systolic
90mmHg diastolic

Question 8

Hypotension MAP is <___mmHg
This can result in…(4)

Answer 8

<60mmHg
Result in:
1. Kidney failure
2. Pancreatitis
3. Heart arrhythmias
4. Cognitive dysfunction

Question 9

Oscillometric
1. User friendliness
2. Accuracy

Answer 9

1. Quick, easy
2. Least accurate

Question 10

Doppler is more ___ then oscillometric, especially cats and ___ dogs

Answer 10

1. Accurate
2. Small dogs

Question 11

Central Venous Pressure needs ___ catheter in place

Answer 11

Jugular

Question 12

Where should the cuff for an oscillomentric reading be placed?
How many readings should you take?

Answer 12

1. Artery (carpal or tarsal)
2. Ideally 3

Question 13

Width of a cuff for BP readings should be ___% of the leg at measurement location.

Answer 13

40%

Question 14

Too small of a cuff:
Too large of a cuff:

Answer 14

Too small: Artificially high result
Too large: Artificially low result

Question 15

Steps for doppler reading (9)
Hint: Think of what’s needed for set up, positioning, and how to use the machine

Answer 15

1. Choose correct cuff size & quiet location.
2. Shave animal over pulse point.
3. Place cuff proximal to pulse point with attached sphygmomanometer with animal in relaxed lateral recumb.
4. Utilized ultrasound gal to achieve ideal contact of doppler probe on pulse point.
5. Listen for flow of blood.
6. Pump sphygmomanometer until sound is silent.
7. Slowly release cuff pressure watching the gauge
8. Record systolic & diastolic readings
9. Repeat 3x for accurate reading

Question 16

When interpreting results from a doppler, the first return is the ___ sound and the return of full sound is ___ pressure

Answer 16

1. Systolic
2. Diastolic
