Flashcards in Physiologic Monitoring part 1 Deck (56):
1

Arterial blood pressure is a complex function of both

Cardiac output and
Vesicular input

2

that the presence of a normal blood pressure is evidence that cardiac output and tissue perfusion are adequate

False

3

Arterial blood pressure that's desirable in many circumstances

Noninvasive monitoring

4

If the cuff is too narrow (relative to the extremity), the measured pressure will be

Elevated

5

measuring BP also require some means for detecting the presence or absence of

arterial pulsations like

Korotkoff sounds
Osscilation ( pwede kahit maingay )

6

Sounds which are heard over an artery distal to the cuff

Korotkoff sounds

7

reappearance of the pulse is indicated by flashing of a light-emitting diode

Pulse oximeter

8

reappearance of the pulse produces an audible amplified signal

Doppler stethoscope

9

Devices that measure pressure oscillations in the inflatable bladder encircling the extremity to detect arterial pulsations

Oscilometers

10

positioned over the brachial artery as a pulse detector

piezoelectric crystal

11

Most accurate

Osccilometry

12

Beat to beat basis
Infrared light

PHOTOPLETHYSMOGRAPHY

13

the pressure in the cuff reflects the pressure in the digital artery

Photoplethysmography

14

PHOTOPLETHYSMOGRAPHY less accurate in patient with

Hypotension and
Hypothermia

15

Arterial catheterization has no absolute contraindication but it has relative contraindications which is

All about hemodynamic

16

Arterial catheterization site

Radial artery 2.Axillary artery 3.Femoral artery 4.Dorsalis pedis artery 5.Superficial femoral artery 6.Brachial artery

17

Most commonly used site for intra-arterial pressure

Radial artery

18

Assess ulnar artery

Allen's test

19

For long term monitoring
Close to aorta
Located near neuro vascular structure

Axillary artery

20

Large size and superficial location •Prone to atherosclerosis •Difficult to keep clean

Femoral artery

21

Surgical exposure is required •Neurologic complications observed

Dorsal is pedis artery

22

Surgical exposure is required •Neurologic complications observed

Superficial temporal artery

23

For short term use only •Median nerve contracture •(Volkmann's contracture

Brachial artery

24

Infection in arterial catheterization if catheter place in

>4days

25

The incidence of thrombosis is increased when

Larger caliber
Extend period of time.

26

The incidence of thrombosis can be minimized by using

20 gauge or smaller

27

Indication of arterial catheterization

For continous BP monitoring

28

Normal CVP measurement:

4-7 mmH2O

29

Easiest to cannulate •Pneumothorax - most common complication •Difficult to control bleeding

Subclavian vein

30

Lower risk of pneumothorax •Arterial puncture - most common complication

Internal jugular vein

31

CVP monitoring indication

For blood and fluid replacement

32

Normal CVP
Low CVP
High CVP

4-7cm
0-3 cm
8-20 cm

33

Cannulation of the Superior Vena Cava through

Basilic or Cephalic Veins

34

connected to IV set w/ a three way stopcock

Manometer

35

CVP monitoring

Zero point should be at level of the

Atrium or approximately at midaxillary line

36

The limb leads are defined as: •

Lead I (LA-RA) •
Lead II (LL-RA), and •
Lead III (LL-LA

37

Most lethal complication that ECG should monitor

Dysrhythmias

38

the most sensitive for detecting perioperative ischemia and infarction

Precordial lead V4

39

The force of muscle contraction depends on the initial length of the cardiac fibers

Starling law of the heart

40

Is determined by end-diastolic volume (EDV

Preload

41

Defined as the force resisting fiber shortening once systole begins

Afterload

42

afterload is commonly approximated by calculating

systemic vascular resistance

43

Defined as mean arterial pressure (MAP) divided by cardiac output

Systemic vascular resistance

44

Defined as the inotropic state of the myocardium

Contractility

45

Pulmonary artery catheter

Balloon
Thermistor
2channels

Tip
Near tip
Tip and 20 cm proximal to the tip

46

Used for pressure monitoring and the injection of the thermal indicator for determinations of cardiac output

Final two channels of PAC

47

calculation of cardiac output using the thermodilution technique in PAC

Thermistor

48

Preferred per cutaneous area for placement of PAC

Jugular or
Subclavian

49

PAC

Carries the lowest risk of complications •The path of the catheter from this site into the right atrium is straight

Right internal jugular vein

50

PAC

Disadvantage if right jugular vein

more difficult to keep occlusive dressings

51

PAC

The anatomic landmarks in the subclavian position are quite constant, even in patients with anasarca or massive obesity; •The subclavian vein is always attached to the deep (concave) surface of the clavicle

Subclavian vein cannulation

52

PAC

Jugular difficult to discern

Obese patient

Pero ginagamit an ng ultrasound ang jugular

53

PAC

method of percutaneous insertion of a catheter into a blood vessel or space. •A needle is used to puncture the structure and a guide wire is threaded through the needle; when the needle is withdrawn, a catheter is threaded over the wire; the wire is then withdrawn, leaving the catheter in place

Seldinger technique

54

4 ports color

Balloon - red
Distal - yellow
Proximal - blue
Thermistor -

55

equipped with a side port, which can be used for administering fluid

Introducer sheath

56

The pressure exerted by blood in the systemic arterial system
