Study Notes

Vital Signs

  • Vital signs include temperature, pulse, respiration rate, oxygen saturation, and blood pressure.
  • Temperature reflects the balance between heat production and loss, indicates infection, inflammation, or thermoregulation issues. Common routes to measure are oral, axillary, tympanic, and rectal. Normal range for adults is 36.7°C-37.5°C.
  • Pulse (Heart Rate) is a wave of blood flow in arteries, indicates cardiovascular status and rhythm abnormalities, measured in beats per minute (bpm). Normal range for adults is 60-100 bpm. Common sites to measure are radial, carotid, brachial, femoral, popliteal, posterior tibial, and dorsalis pedis arteries.
  • Respiration Rate (RR) measures the rate, rhythm, and depth of breathing. Normal range for adults is 12-20 breaths per minute.
  • Oxygen Saturation (SpO2) measures the percentage of hemoglobin saturated with oxygen. Normal range is 95-100%.
  • Blood Pressure (BP) is the force of blood against artery walls, measured in millimeters of mercury (mmHg). Normal range for adults is 120/80 mmHg. Systolic pressure is the maximum pressure exerted during contraction, and diastolic pressure is the pressure exerted between contractions.

Temperature

  • Reflects the balance between heat production and loss.
  • Common routes include oral, rectal, axillary, and tympanic.
  • Rectal readings are closest to core temperature, reliable for infants (<2 years).
  • Oral is quick and accessible.
  • Axillary is non-invasive, good for children.
  • Tympanic is quick and accessible.
  • Normal oral ranges from 35.8°C to 37.3°C.
  • Normal axillary ranges from 34.8°C to 36.3°C.
  • Normal tympanic ranges from 36.1°C to 37.9°C.
  • Normal rectal ranges from 36.8°C to 38.2°C.

Pulse

  • Measured by palpating or auscultating the pulse.
  • Normal adult range is 60 to 100 bpm.
  • Factors affecting pulse include exercise, temperature, emotions, pain, drugs, hemorrhage, and body position.
  • Variations such as tachycardia (>100 bpm) and bradycardia (<60 bpm) indicate potential issues.
  • The strength of the pulse (bounding, strong, weak, thready, absent) and rhythm (regular or irregular) are also assessed.
  • Equal pulse strength bilaterally is important.

Respiration Rate

  • Measures the rate, rhythm, and depth of breathing. Normal range for adults is usually 12-20 breaths per minute.
  • Factors that influence RR include exercise, pain, anxiety, medications, body position, neurological injury, hemoglobin function, smoking, and cardiovascular function.

Oxygen Saturation (SpO2)

  • Measures the percentage of hemoglobin saturated with oxygen.
  • Normal range is 95-100%.
  • Assess using pulse oximeter.
  • Factors affecting SpO2 include light interference, movement, intravascular dyes, and jaundice.

Blood Pressure

  • Measures the force of blood against artery walls.

  • Components are systolic and diastolic pressure.

  • Normal adult range is 120/80 mmHg.

  • Measured using a sphygmomanometer (manual) or automated devices.

  • Factors include age, gender, ethnicity, diurnal rhythm, weight, exercise, emotions, and stress.

Pain Assessment

  • Pain is the 5th vital sign.
  • Important to assess for underlying conditions and responses to interventions.
  • Assessment tools include rating scales (e.g., Numerical Rating Scale, 0-10), PQRSTU, and subjective reporting.
  • Factors influencing pain include emotional state, fatigue, cultural background, and pain tolerance.
