Flashcards in A load of random Cardio Stuff you should know by now Deck (32):
1

In foetal life - the right atrium and left atrium are connected by what structure?

foramen ovale

2

An atrial septal defect allows the shunting of blood between the

right and left atrium

3

Examples beta blocker drugs

atenolol

propranalol

4

What are beta blockers commonly used to treat?

angina

post MI

heart failure

arrhythmias

hypertension

anxiety

5

Digoxin uses

atrial fibrillation

heart failure

6

Pleural effusions can be either transudate or exudate according to their protein concentration.

transudate is

exudate is

<30g/L

>30g/L

7

Pleural effusion

water on the lungs

fluid in the layers of the pleura

8

Transudate is common in ...

heart failure

hypothydroism

9

exudate is common in

infection

connective tissue disease

pulmonary embolism

lung cancer

10

Pleural effusion symptoms

SOB

Cough

chest pain

11

hyperventilation is followed by a small spell of

apnoea


(stop breathing)

12

Muscles of inspiration and expiration are ..... muscles that are under ...... control

skeletal



voluntary

13

Doral-respiratory group in the medulla co-ordinates the contraction of the

diaphragm

14

most potent regulator of ventilation is the

chemical changes in arterial blood

15

central chemoreceptors are found in the medulla and respond to alteration in

PCO2

16

peripheral chemoreceptors are found in the

aortic and carotid bodies

17

peripheral chemoreceptors respond to changes in

PO2 and pH

18

central chemoreceptors can respond to a change in H+ in the

CSF to increase ventilation

19

hypoventialion


acid or alkalosis

acidosis

20

hyperventilation

acid or alkalosis

alkalosis

21

NO can be a bad sedative to use as it blunts the

peripheral chemoreceptor response to falling PO2

22

emphysema will do what to elasticity?

decrease it

23

emphysema will do what to compliance?

increase it

24

Boyles law

the pressure exerted by a gas is inversely proportional to its volume

25

transpulmonary pressure is the

difference between alveolar and fintrapleural pressure

26

PO2 in air is usually

160mmHg

27

PO2 in alveolar air is usually

100mmHg

28

PO2 in mixed venous blood is usually

40mmHg

29

PO2 in mixed venous blood is usually

40mmHg

30

Law of Laplace equation

pressure is 2 times surface area over radius

31

surfactant will do what to lung compliance?

increase it

32

surfactant will do what to lung recoil?

decrease it
