1
New cards

blood pressure

force of the blood pushing against artery walls, written as systolic/diastolic reading

average: 120/80mmHg

2
New cards

systolic

active contractions of the heart

3
New cards

diastolic

relaxation of heart between beats

4
New cards

heart rate

heart beats per minute (BPM)

average: 80 BPM

5
New cards

respiratory rate

the number of breaths taken per minute, typically measured in breaths per minute (BPM) during rest

average: 12-20 breaths per minute

6
New cards

temperature

internal temperature of body, measured in C or F

average: 98.5F

7
New cards

oximetry

the measurement of oxygen saturation in the blood

average: 95-100%

8
New cards

what artery is used to measure BP?

brachial artery

9
New cards

ideal conditions to take BP

  • pt sitting for 5 mins

  • brachial artery at level of heart

  • pt to avoid exercise, tobacco, and caffeine for 30 mins prior

  • room warm and quiet

  • cuff/stethoscope to bare skin


10
New cards

fistula

a surgical arterial bypass that attaches a vein to an artery

11
New cards

who most commonly has a fistula to be aware of when taking BP?

dialysis pts

12
New cards

auscultatory gap

silent interval between systolic and diastolic pressures

  • associated with arterial stiffness and atherosclerotic disease


13
New cards

white coat syndrome

higher BP while evaluating in office, at home BP measurements more accurate

14
New cards

elevated BP

systolic reading 120-129 AND diastolic reading <80

15
New cards

stage 1 hypertension

systolic reading 130-139 OR diastolic reading 80-89

16
New cards

stage 2 hypertension

systolic reading 140 or higher OR diastolic reading 90 or higher

17
New cards

hypertension crisis

systolic reading higher than 180 AND/OR diastolic reading higher than 120

18
New cards

evidence for end-organ damage due to htn

retinopathy changes in eyes, EKG hypertrophy, abnormal mini mental stress exam/neuro exam, abnormal urinalysis (excess protein)

19
New cards

symptoms of LBP

generalized weakness, visual changes, syncope

20
New cards

what can cause LBP?

medications, blood loss, dehydration

21
New cards

orthostatic blood pressure

BP changes from when laying, sitting, to standing

22
New cards

worrisome orthostatic BP changes

systolic reading changes >20mmHg

diastolic reading changes >10mmHg
