Vital Signs Flashcards
vital signs
objective measurements like temperature, heart rate, blood pressure, respiratory rate, and oxygenation
temperature
-reported in C or F
-measured with thermometer at specific sites like under tongue, armpit, ear canal, and rectum
-normal adult temperature is 37 C and 98.6 F
hypothermia
condition of low temperature (<35 C)
normothermia
condition of normal temperature
hyperthermia
condition of high temperature (>38 C)
thermoregulation
maintenance of body temperature
heart rate
-reported in beats per minute
-measured by: pulse oximeter on distal finger tip, electrocardiogram (ECG/EKG), felt and counted by hand for 1 min at pulse sites, and auscultated and counted for 1 min with stethoscope
-normal adult heart rate: 60-100 beats per min
tachycardia
condition of fast heart rate (>100bpm)
bradycardia
condition of slow heart rate (<60bpm)
arrhythmia/dysrhythmia
condition of abnormal heart rhythm
heart rate pulse sites
temporal, FEMORAL, popliteal, posterior tibial, CAROTID, BRACHIAL, RADIAL, and dorsalis pedis
pulse measurement rate
-0=absent
-1+=thready/weak
-2+=normal pulse
-3+=bounding
blood pressure
-reported as systolic blood pressure (SBP)/diastolic blood pressure (DBP) in millimeters of mercury (mmHg)
-measured with sphygmomanometer (BP cuff) at brachial site
-can be taken manually with stethoscope and BP cuff or electronically
-normal adult blood pressure:
SBP: 100-140 mmHg
DBP: 60-90 mmHG
MAP: >65
hypotension
low blood pressure (<100/60)
hypertension
high blood pressure (>140/90)
normotensive
normal blood pressure
MAP
mean arterial pressure (2(DBP+SBP)/3)
respiratory rate
-reported in breaths per minute
-measured: observing chest fall and rise for 1 min, auscultation with stethoscope and count rate for 1 min
-can assess rhythm (regular/irregular) and quality (shallow/deep)
-normal adult respiratory rate: 12-20 breaths per minute
-pnea
breathing
spir/o
breathing
tachypneic/tachypnea
condition of rapid breathing (>20 bpm)
