1

__________ artery provides more blood to the hand?

ULNA artery

2

In terms of bleeding, Arteries do _______ and Veins do _________?

Arteries = squirt
Veins = pool out...

3

What is the #1 answer to Bleeding?

- Hold pressure!

4

In terms of Blood Pressure which number do we worry about more?

Diastolic

5

What is Diastolic pressure?

The lowest pressure within the arteries

6

What is Systolic pressure?

Pressure at the height of the pressure pulse within the arteries

7

What is Pulse Pressure?

The difference between systolic and diastolic pressure

8

What does MAP mean?

Mean Arterial Pressure

9

What is Mean Arterial Pressure?

The average pressure in the arterial system during ventricular contraction and relaxation

10

Age = and increase in ____________?

Hypertension

11

The Highest pressure is in the ________?

AORTA

12

___________________________ occurs at the beginning of the cardiac cycle when the ventricles are filling up with blood?

Diastolic Blood Pressure

13

_____________________________ occurs near the end of cardiac cycle when the ventricles are contracting

Systolic Blood Pressure

14

What is arterial blood pressure?

Represents the pressure of the blood as it moves through the arterial system

* Blood Pressure differs w/ every heart beat

15

Blood Pressure can be affected by what?

- Stress
- Drugs (coccaine/heroin= elevation)
- Diseases
- Exercise
- Nutritional factors
- Momentarily when we stand

16

Regulation of BP is found where?

In the Medulla of the brain stem

17

Respiratory and Cardiac centers are found where?

Behind the head
( brain stem)

18

Epinephrine is a _______________ which is released from the ________________?

Vasoconstrictor
Adrenal glands

19

Why is Epinephrine given?

Given to increase HR and blood flow

- which increases BP....?

20

Renin-angiotensin-aldosterone system plays a role in what?

A Central role in BP regulation

21

Sodium 🧂 and water 💧 = ___________ ?

Buddies!
(Always together)

22

What is the role of the Renin-angiotensin-aldosterone system?

Retain sodium and water which will increase blood volume and pressure



Hypertensive = Excrete
Hypotensive = Retain (to get BP up)

23

_________________ is found in the carotid bodies of the aorta

Arterial chemoreceptors

24

Chemoreceptors are found where?

In the AORTA

25

With orthostatic hypotension a patient can be either ____________ or ____________

Symptomatic OR asymptomatic

26

In a patient with orthostatic hypotension what should you do if symptoms occur?

Lay or sit the patient down!

27

Common causes of Orthostatic Hypotension?

LOSS OF VOLUME!!

28

Manifestations of Orthostatic Hypotension?

- Dizziness
- Visual changes
- Diaphoresis
- Poor concentration while standing
- Palpitations
- Tremor
- Anxiety
- Presyncope, and in some cases syncope

29

Treatment for Orthostatic Hypotension?

FLUIDS!!!
(Increase Volume)

30

_____________is know as the silent killer ?

Hypertension
