1

What are the tools used for taking blood pressure?

  • Stethoscope
  • Sphygmomanometer

2

When placing the BP cuff on the arm, what artery is being used for taking blood pressure?

Brachial

3

When taking a blood pressure, the diaphragm of the stethoscope is placed... 

on the patient's brachial artery under BP cuff

4

Taking a blood pressure reading

Why do we inflate the cuff to 180 mmHg?

To ensure that the pressure is above aortic systolic pressure so the cuff pressure seals the artery and prevents blood flow.

5

Taking a blood pressure reading

We reduce pressure in the cuff by

slowly opening the air release valve

6

Taking a blood pressure reading

The first reading is taken when

the first heartbeat is heard

7

Taking a blood pressure reading

The second reading is taken...

as soon as the heartbeat is no longer heard.

8

Taking a blood pressure reading

The number above the fraction line of a reading is known as

systole

9

Taking a blood pressure reading

The number below the line is known as

diastole

10

Prior to inflating the cuff, do we here a pulse?

Why?

  • No
  • Blood is flowing freely and there is no variance of pressure upon the cuff

11

After inflating the cuff, do we hear a heartbeat?

Why?

  • No
  • Because all blood flow has been cut off by the bp cuff

12

The two easiest places to take a pulse are

  • Coratid artery at neck
  • Radial artery at wrist

13

What causes the sounds we hear when taking blood pressure?

The pressure and lack of pressure put upon the cuff by the contractions of the heart.

14

What would happen if you left an inflated blood pressure cuff on?

It would cut the flow of blood to all areas below the cuff. 

15

Occasionally, a shygmomanometer needs to be inflated to 200 mmHg. Why?

The patient's systolic pressure is more than 180 mmHg

16

The higher blood pressure represents the

systolic pressure of the heart

17

The lower blood pressure number represents the

diastolic pressure of the heart

18

What are the 5 parts of the stethoscope?

Briefly describe purpose of each.

  1. Earpieces: go in your ears to hear
  2. Eartubes: transmitting sound to earpiecs
  3. Tube: transmitting sound to ear tubes
  4. Stem: used to attach diaphragm
  5. Diaphragm: placed on body to pick up internal sounds

19

What are the 5 parts of the sphygmomanometer?

Brifely describe each.

  1. Cuff: attached to upper arm just above elbow
  2. Bladder: holds air to control blood flow
  3. Inflation bulb: used to pump air into bladder
  4. Release valve: controls the release of air from bladder
  5. Manometer: indicates pressure readings
