22
Q

korotkoff sounds:
- unobstructed =

A

no vibrations/sounds

23
Q

phase 1: first recognition or “faint, clear” sounds or “sharp thuds” that increase in intensity

A

SBP

24
Q

phase 5: sounds are no longer audible or “disappear”

A

DBP

25
Q
  • body arm positions
    • no practical difference in BP when supine vs sitting
    • statistically slightly higher SBP (6-7 mm Hg) and DBP (1 mm Hg) when supine
    • BP is higher when arm is below the heart vs above
A

factor affecting blood pressure measurements

26
Q
  • cuffs
    • too small – overestimated BP
    • too large – underestimate BP
A

factor affecting blood pressure measurements

27
Q

Effects of aerobic exercise on BP:
- _ increases linearly with increasing exercise intensities
- Q increases significantly during graded exercise
- increases in flow/pressure are “absorbed” by elasticity of vessels dampening the change in blood flow (TPR decrease slightly)
- If TPR did not decrease, pressures would be extremely high – busrting

A

systole blood pressure

28
Q

Effects of aerobic exercise on BP:
- _: slightly increases, slightly decreases, or remains unchanged (~10 mm Hg)

A

diastole blood pressure

29
Q

Effects of aerobic exercise on BP:
- within 5-8 minutes of exercise cessation, BP usually returns _
- Return depends upon:
- type
- intensity
- duration

A

to pre-exercise level

30
Q

Effects of aerobic exercise on BP:
- SBP may drop slightly lower than pre-exercise SBP and remain _ following exercise

A

lower for several hours

31
Q

Effects of aerobic exercise on BP:
- _: can lead to syncope
- passive recovery – cessation of muscle pump – venous pooling – reduced venous return and vasoconstriction
- loss of plasma volume (sweating)

A

recovery hypotension

32
Q

age, muscle mass, fitness level, smoking

A

factors affecting BP during exercise

33
Q

type of exercise and exercise protocol
- Resistance training produces > BP than rhythmic aerobic exercise
- some aerobic exercises (cycling) produce greater BP than other aerobic exercise (treadmill)

A

factors affecting BP during exercise

34
Q

pulse pressure =

A

SBP-DBP

35
Q

difference between SBP and DBP
- reflects vascular compliance in large arteries
- high PP = increased risk of MI
- 40 - normal
- > 60 - may be at risk

A

pulse pressure (PP)

36
Q

average force against arterial walls during the cardiac cycle
- based on actual arterial pressure that would be sustained if blood flow was constant and not pulsating
- slightly lower than average value of SBP and DBP

A

mean arterial pressure (MAP)

37
Q

Q =

A

MAP/TPR

38
Q

MAP =

A

DBP + (0.333 [SBP-DBP])

39
Q
  • reflects how hard the heart is working depending on rate (HR) and resistance (SBP)
  • believed to be related to physical fitness (healthy persons)
    • lower at rest
    • higher maximal
A

rate pressure product (RPP)

40
Q

RPP =

A

HR (bpm) x SBP (mm Hg) / 100

41
Q

rate pressure product:
- considering both HR and BP offers a better estimate of _ than HR alone

A

myocardial O2 consumption

42
Q
  • aka: postural hypotension
  • move from supine to standing
  • venous pooling occurs immediately (gravity); Q decreases
  • baroreceptors sense a decrease in BP and sends a message to the medulla oblongata to increase BP – venous return
    • vasoconstriction
    • increase in HR and SV
A

orthostatic intolerance (orthostatic hypotension)

43
Q
  • high risk for future CV morbidity and mortality
  • primary: cause of HT is not known (~90% of HT in adults)
  • secondary: caused by known endocrine or structural disorders
A

hypertension (high BP)

44
Q
  • more likely to accelerate atherosclerosis
  • may cause occlusions (blood clots) and ruptures ~20 years prior to normotensives
  • BP can be affected by non-pathological factors; should not classify persons from a single reading
A

hypertension

45
Q

Systolic = less than 120
AND
Diastolic = less than 80

A

Blood pressure - normal

46
Q

Systolic = 120-129
AND
Diastolic = less than 80

A

Blood pressure - elevated

47
Q

Systolic = 130-139
OR
Diastolic = 80-89

A

Blood pressure - high blood pressure (hypertension) stage 1

48
Q

Systolic = 140 or higher
OR
Diastolic = 90 or higher

A

Blood pressure - high blood pressure (hypertension) stage 2

49
Q

Systolic = higher than 180
AND/OR
Diastolic = higher than 120

A

Blood pressure - hypertensive crisis (consult doctor immediately)
