Vitals - Midterm Flashcards
what are vitals
objective measure of physiological function
what are vitals used for
a baseline
when is a baseline needed
patients over 65 or under 2
debilitated patients
sedentary patients
patient with cardiovascular issues
HR/pulse rate
heart rate: direct measurement taken at heart w/ EKG, palpation on heart of ventricular beats per min
pulse rate: indirect measurement of contraction of left ventricle
-not always 1:1 with HR b/c not all ventricular contracts are strong enough to produce a pulse distally
amplitude of pulse rate
0 = absent
1+ = weak/thready
2+ = normal
3+ = strong
4+ = bouncing
what is peripheral patency
the ability to get blood to an area of the body
can provide signs of occlusion (blockage or vascular insufficiency)
measured in distal pulse and graded on amplitude
capillary refill
what is capillary refill
push down on an area to occlude it then remove pressure - color should return >2 seconds
can also be measured w/ reactive hyperemia test
-elevate limb for 1 minute then return to level and color should be normal in 2-3 seconds
heart rate norms
<6 months = 100-160
1 yr= 90-150
3 yr = 80-115
5 yr = 70-115
10 to adult = 60-100
Bradycardia = <60 bpm
tachycardia >100 bpm
max HR
208 - (0.7 x age) for healthy adults
1 SD of HR max is 10-12 bpm
target HR
minimal HR a person should sustain during exercise to train the CV system effectively
HR reserve method
HR reserve method
HR + ([HR max - HR rest] x 0.60 or 0.80)
normal HR response to exercise
increases, plateaus and decreases following intensity of exercise
should begin to return to resting value after 2 minutes
palpation of HR
HR never measured with pulsoximeter
30 seconds over a distal part with pads of index finger and middle finger
what is blood pressure
reflects CO, peripheral vascular resistance, and other hemodynamic factors
measured w/ sphygmomanometer (indirect measure of pressure of blood flow in an artery)
what is considered systolic
systolic - first sound (BP at time of contraction of ventricle, palpated pulses)
