Vital Signs Flashcards
the 6 vital signs
pulse, respiration, BP, temp, pain, and walking speed
components of pulse
pulse force, pulse ryhthm, pulse rate,
normal adult pulse rates
60-80 bpm
normal pulse rate of children (1-8)
80-100 bpm
normal pulse rate of infants (less than 1 year)
100-120 bpm
normal pulse rate of highly trained athletes
40-60 bpm
tachycardia
pulse rate greater than 100 bpm
bradycardia
pulse rate lower than 60 bpm
pulse rhythm
Regular: pulses felt at typical intervals.
Irregular: pulses felt at variable intervals.
pulse force
0=absent
1+=diminished or weak (barely palpable)
2+=normal (easily palpable)
3+=increased force (very easily palpable)
4+=bounding (unable to obliterate with palpation pressure)
Thready=no interval between pulses (very weak and rapid)
factors affecting the pulse
age, gender, ANS, environment, drugs, pregnancy, excitement/nerves, arrythmias, POTS, and biofeedback (good effect)
components of respiration
breathing rate, ryhthm, and depth
oxygen saturation
measure of oxygen within arterial blood
oxygen saturation is dependent upon:
O2 availability, gas exchange in the lungs, concentration of hemoglobin for O2,
arterial blood gases
SaO2 describes the O2 saturation of the arterial blood; obtained from blood draw
pulse oximetry
SpO2; use of probe and wavelengths of light reflected from the blood.
normal SpO2 values
96-100% (less than 90% may need supplemental O2)
hypoxemia
deficient oxygenation of blood
