Vital Signs Flashcards
Normal vital signs change with
age, sex, weight, exercise, tolerance, and condition
Baseline
use to identify changes in patient status
series of vital sign measurements establishes patient trends
Frequency
dependent on patient status and clinical judgement
Interpretation
Compare the patient’s results with normal values
Medical history and diagnosis a consideration
Normal temperature range
97.6-99.6 F
Average oral temperature
98.6
Hyperthermia temperature
> 104F
fever is a body defense
Hypothermia temperature
<95F
Oral temperature
most common
Axillary (armpit)
least accurate
Tympanic (ear)
used most in children
Temporal (forhead)
usually a bit higher than your actual temperature
Rectal (anus)
last resort in newborns but most accurate
Temperature measurement should occur at least
1 hour after exercise or bathing
30 minutes after smoking or consuming hot or cold food or beverages
Normal Heart Rate
60-100 bpm
fluctuates with exercise, illness, injury, emotions
What gender has a higher heart rate
females
Bradycardia heart rate
<60 bpm
resting or heart block
Tachycardia heart rate
> 100 bpm
shock, hemorrhage, fever, acute pain, drugs
Sites for assessing pulses
Carotid (most used in emergencies)
brachial
radial (most common)
dorsalis pedis
apical (stethoscope)
posterior tibial
Tips for assessing pulse
Never use your thumb
count for 30 seconds x2
irregular = full minute
infants = apical 1 minute
Infants resting heart rate is
higher than young children and adults
Heart rate will do what with age
decrease
Respirations average range
12-20
affected by age, exercise, respiratory disease, medications, pain, emotions
Bradypnea respiration rate
<12
head trauma, medications
Tachypnea respiration rate
> 20
fever, illness
Newborns respiration rate is
higher than chids
Average blood pressure for adults
120/80
Hypertension blood pressure
elevated
head trauma, medications
Hypotension blood pressure
abrupt decline
fever, illness, medications
How to position a patient for blood pressure
sitting
feet on ground
artery same height as heart
accurate size cuff
Arm too high what happens to blood pressure
low BP
Arm too low what happens to blood pressure
high BP
Infants blood pressure is
low compared to kids and adults
Older adults blood pressure
rises as people age
