Study Notes

Vital Signs (VSs)

Vital signs assess critical physiological functions: temperature, pulse, respiration, and blood pressure.
Accurate measurement and documentation of VSs are essential for patient care.
Normal VSs do not guarantee overall physiological well-being; context is crucial for assessment.
Additional factors like pain, oxygen saturation, smoking status, and emotional distress are also important in patient assessments.

Core Temperature

Core temperature is measured deep within the body, typically near the hypothalamus.
Rectal measurements indicate core temperature, while oral and axillary measurements indicate surface temperature.
Normal internal temperature ranges from 36.1°C to 38.2°C (97°F to 100.8°F).
Core temperature is generally higher than surface temperature by about 0.6°C to 1.2°C (1°F to 2°F).

Temperature Variability

Body temperature varies from individual to individual and can fluctuate based on age, exercise, and environment.
The traditional average normal temperature of 37°C (98.6°F) is now considered high; recent studies suggest a mean of 36.6°C (97.9°F) with variations for older adults and by gender.
Temporary variations in temperature may not be significant, but continuous elevation should prompt further evaluation.

Regulation of Body Temperature

The hypothalamus manages body temperature through sensory feedback mechanisms.
Decreasing body temperature triggers mechanisms like peripheral vasodilation and sweating.
Increasing body temperature leads to shivering and vasoconstriction to conserve heat.

Pulse

Pulse reflects the rhythmic expansion of arteries from blood pumped by heart contractions.
Normal pulse rate for adults is 60 to 100 beats/min, averaging 70 to 80 beats/min.
Production of the pulse is linked to stroke volume and cardiac output; average stroke volume in healthy adults is 70 mL.

Factors Influencing Pulse Rate

Pulse rate varies with blood volume, heart function, arterial elasticity, and nervous system health.
Developmental factors: newborns have higher pulse rates, which stabilize in childhood and decrease with age.
Gender influences pulse; adult women typically have higher pulse rates than men.
Exercise increases pulse rate temporarily, with well-conditioned individuals returning to baseline faster than less fit individuals.

Importance of Continuous Monitoring

Consistent monitoring and evaluation of vital signs can detect significant physiological changes and guide patient care decisions.
Regular assessment of pulse provides quick insights into heart and circulatory health, important for identifying needs for advanced monitoring.
