25
How much do we add after radial artery disappears for systolic?
30mmHg
26
Define Auscultatory Gap (potential problem)
Silent interval that may be present between S and D
27
What can the AG do?
Underestimate S and overestimate D
28
Which side of bell goes over brachial artery?
Bell (low pitch sounds)
29
What are the flow sounds called?
Korotkoff sounds
30
What should our rate of deflation be?
2-3mmHg per second
31
What is systolic?
When we hear sounds of at least 2 consective beats with cuff on
32
What is D with the cuff?
Whenever the turbulent flow sounds disappear
33
Should BP be taken in both arms at least once?
Yes
34
Is there normally a 5-10mmHg pressure difference in the arms?
yes
35
What is a pressure difference of 10-15mmHg in each arm occur in?
1. Subclavian Steal Syndrome | 2. Aortic Dissection
36
Do we assign worst possible classification?
Yes
37
Is a single elevate BP reading sufficient to establish diagnosis of HTN?
No
38
Normal BP
<120 and <80
39
Pre HTN
120-139 or 80-89
40
HTN Stage 1
140-159 or 90-99
41
HTN Stage 2
>160 or >100 (or =)
42
Do we need to take into account history of BP's regardless of our findings?
Yes (someone might live normally with HTN, if they come back w/ a normal BP, that would be considered abnormal)
43
Define Orthostatic Hypotension
Decrease in systolic blood pressure of 20 mm Hg or a decrease in diastolic blood pressure of 10 mm Hg within three minutes of standing when compared with blood pressure from the sitting or supine position
44
2 positions we measure BP and HR in OH?
1. Resting from 3-10 minutes | 2. Within 3 minutes after pt stands up
45
What is normal when a pt stands up?
SBO drops slightly or remains unchanged, while DBP rises slightly
46
What else is signficant for OH?
Accompanied symptoms of tachycardia
47
JVP
Jugular Venous Pressure and Pulsations
48
What does JVD reflect?
Pressure in R atrium OR central venous pressure
49
Where is JVD best assessed?
R internal jugular vein
50
What has a recent study said about JVD?
R external jugular is better than R internal for measuring
51
What does JVD fall with? Rise?
Loss of blood; R or L HF, pulmonary HTN, tricuspid stenosis, and pericardial compression or tamponade
52
How do we estimate level of JVP (2 ways)
1. Find highest point of oscillation in internal jugular vein 2. Point above which external jugular vein appears collapsed
53
How is JVP measured?
Vertical distance above sternal angle
54
Whatever you measure
5cm
55
Higher the JVP measurement, what?
Higher the PP
56
Why do we ausciltate the carotid artery?
For bruits or thrills
57
Do we want high pressure on the carotid sinus?
NO
58
Do we press on both carotids at the same time?
NO; reduces blood flow to brain and could induce syncope
59
What is the amplitude of the carotid pulse correlate well with?
Pulse pressure
60
What do we look for in the contoud of the pulser wave?
1. Speed of upstroke 2. Duration of its summit 3. Speed of downstroke
61
How is the normal upstroke?
Brisk
62
Is the downstroke less abrupt than upstroke?
No
63
Specific formula to Small, Weak Pulses
Decreased CO = SV x HR
64
Pulsus Alternans specific symtpom
L ventricular HF
65
Bigeminal Pulse specific symtpom
Premature contraction
66
Parasoxical Pulse
Palpable decrease in pulse amplitude on quiet inspiration
67
Do we need BP cuff is paradoxical sign is less pronounced?
Yes
68
How much do SBP drop in parasoxical?
>10mmHg in inspiration
69
Where do we find paradoxical pulse?
Percardial tamponade and frequently in exacernations of asthma and COPD
70
Where is paradoxical sometimes noted?
Constrictive pericarditis
71
Where is the Point of Maximal Impulse? (PMI)
Anterior chest
72
Where is the Point of Maximal Impulse? (PMI)
Anterior chest
73
Apex beat is how palpable?
25%-40% of healthy adults in supine position 50% of healthy adults in L lateral decubitus position
74
How do we palpate for heaves, lifts, or thrills?
Palm or fingerpads
75
What are lifts and heaves?
Sustained impulses
76
How are lifts and heaves produced?
Enlarged R or L ventricle or atrium and occaionally by ventricular aneurysms
77
How do we check thrills?
Press with the ball of your hand to check for a buzzing or vibratory sensation from underlying vascular turbulence from heart murmurs
