Cardiovascular- The Exam: BP, Respiration, O2 Sat, and Pain Flashcards
Normal BP
Systolic <120 mm Hg
Diastolic <80 mm Hg
Prehypertension BP
Systolic 120-139 mm Hg
or
Diastolic 80-89 mm Hg
Stage 1 Hypertension BP
Systolic 140-159 mm Hg
or
Diastolic 90-99 mm Hg
can also be called grade 1
Stage 2 Hypertension BP
Systolic 160-179 mm Hg
or
Diastolic 100-109 mm Hg
can also be called grade 2
Hypertensive crisis
Systolic 180+ mm Hg
or
Diastolic 110+ mm Hg
can also be called grade 3
What is hypotension and what may cause it?
- a decrease in BP below normal; BP is not adequate for normal perfusion/oxygenation.
- may be related to bed rest, drugs, arrhythmias, blood loss/shock, or MI
What is orthostatic hypotension
- drop in BP that accompanies changes from supine to standing
- To assess: take BP and HR in supine 5+ min before transfer, take BP and HR immediately upon standing, take BP and HR 3 min after standing
- pt. is orthostatic is systolic drops > 20 mm Hg or if diastolic drops >10 mm HG
Common symptoms of orthostatic hypotension
light-headedness
dizziness
LOB
LE weakness
Pediatric BP range under age 2
Systolic 106-110 mm Hg
Diastolic 59-63 mm Hg
Pediatric BP range age 3-5
Systolic 113-116 mm Hg
Diastolic 67-74 mm Hg
What is Mean Arterial Pressure (MAP)?
- the arterial pressure w/in the large arteries over time; dependent upon mean blood flow and arterial compliance
- calculated by systolic BP + 2(diastolic BP) then divided by 3
- important measure in critical care (ICUs)
What is a normal MAP?
70-110 mm Hg
Normal adult respiration rate (RR)
12-20 breaths per min
Normal newborn RR
30-40 breaths per min
Normal child RR
20-30 breaths per min
