Q

What are the tools used for taking blood pressure?

A
  • Stethoscope
  • Sphygmomanometer
2
Q

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

A

Brachial

3
Q

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

A

on the patient’s brachial artery under BP cuff

4
Q

Taking a blood pressure reading

Why do we inflate the cuff to 180 mmHg?

A

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

5
Q

Taking a blood pressure reading

We reduce pressure in the cuff by

A

slowly opening the air release valve

6
Q

Taking a blood pressure reading

The first reading is taken when

A

the first heartbeat is heard

7
Q

Taking a blood pressure reading

The second reading is taken…

A

as soon as the heartbeat is no longer heard.

8
Q

Taking a blood pressure reading

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

A

systole

9
Q

Taking a blood pressure reading

The number below the line is known as

A

diastole

10
Q

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

Why?

A
  • No
  • Blood is flowing freely and there is no variance of pressure upon the cuff
11
Q

After inflating the cuff, do we hear a heartbeat?

Why?

A
  • No
  • Because all blood flow has been cut off by the bp cuff
12
Q

The two easiest places to take a pulse are

A
  • Coratid artery at neck
  • Radial artery at wrist
13
Q

What causes the sounds we hear when taking blood pressure?

A

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

14
Q

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

A

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

15
Q

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

A

The patient’s systolic pressure is more than 180 mmHg

16
Q

The higher blood pressure represents the

A

systolic pressure of the heart

17
Q

The lower blood pressure number represents the

A

diastolic pressure of the heart

18
Q

What are the 5 parts of the stethoscope?

Briefly describe purpose of each.

A
  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
Q

What are the 5 parts of the sphygmomanometer?

Brifely describe each.

A
  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
