    Environmental Influence on Body Temperature

    Cold environments cause vasoconstriction, narrowing blood vessels to conserve heat. Hot environments lead to vasodilation, widening blood vessels and sweating, to release heat.

    Study Notes

    Vital Signs Assessment

    • General Conditions: Assess consciousness level, facial expressions (happy, sad, pain, pale)
    • Vital Sign Checks: Include body temperature, pulse, respiration, blood pressure, pain assessment, and oxygen saturation.
    • Medical History: Obtain patient's history including present complaints, problems, pain, allergies, and past medical history.

    Body Temperature

    • Normal Range (Adults): 36°C – 37.5°C (Afebrile)
    • Hyperthermia/Fever: 38°C
    • Hyperpyrexia: 41°C
    • Hypothermia: < 36°C
    • Factors Affecting Body Heat Production: Basal metabolic rate, muscle activity, thyroxine output, epinephrine, and fever.

    Heat Loss from the Body

    • Radiation: Heat loss due to a temperature gradient.
    • Conduction: Transfer of heat from one object to another.
    • Convection: Heat loss via air or water movement.
    • Evaporation: Heat loss via sweat evaporating.

    Factors Affecting Body Temperature

    • Age: Infants and children have immature thermoregulatory systems, making them more sensitive to temperature changes; elderly may have lower metabolic rates.
    • Diurnal Variation: Body temperature naturally fluctuates throughout the day, typically lowest in the early morning and highest in the late afternoon/early evening.
    • Exercise: Muscle contractions generate heat.
    • Hormones: Thyroid hormones and epinephrine.
    • Stress: Stress triggers the release of adrenaline increasing metabolic activity & related factors (pulse/respiration).
    • Environment: Cold weather leads to vasoconstriction; hot weather leads to vasodilation and sweating.

    Types of Fever

    • Intermittent: Body temperature returns to normal at least once within 24 hours.
    • Remittent: Temperature fluctuates above baseline, but doesn't reach normal.
    • Relapsing: Periods of fever alternate with periods of normal temperature.
    • Constant: Elevated temperature without returning to normal.
    • Fever Spike: Sudden, brief elevation in temperature that quickly returns to normal.
    • Heat Exhaustion: Excessive heat exposure leading to dehydration and elevated temperature.
    • Heat Stroke: Extremely high body temperature due to prolonged heat exposure.

    Measuring Body Temperature

    • Oral
    • Tympanic Membrane

    Vital Sign - Pulse

    • Factors Affecting Pulse: Age, sex, exercise, stress, medications, and medical conditions.
    • Explanations: Pulse rate higher in infants/children, females generally slightly higher than males, physical activity increases pulse rate.
    • Pulse Rate Variations: tachycardia, bradycardia, dysrhythmia/arrhythmia, affecting volume.
    • Evaluation: Assess rate, rhythm, volume.

    Vital Sign - Respiration

    • Definition: The act of breathing (inspiration/ inhalation & expiration/ exhalation).
    • Ventilation: Air movement in and out of the lungs.
    • Types of Breathing: Costal (thoracic), diaphragmatic (abdominal).

    Respiratory Rate/Quality

    • Terminology: Eupnea, tachypnea, bradypnea, apnea, hyperventilation, hypoventilation.
    • Factors Affecting Respiratory Rate: Exercise, stress, environmental temperature, and lowered oxygen concentrations.

    Vital Sign - Blood Pressure

    • Measurement: Sphygmomanometer/ Dynamap.
    • Units: 120/80 mmHg (systolic/diastolic).
    • Determinants: Pumping action of the heart, peripheral vascular resistance, blood volume, and blood viscosity.
    • Factors Affecting Blood Pressure: Age, exercise, stress, sex, medications, obesity, and diurnal variations.
    • Explanations: Blood pressure generally increases with age, exercise increases blood pressure, stress-related hormones increase BP; menopause-related changes (hormonal shifts) affect woman's BP. Medications, obesity, and diurnal patterns influence BP fluctuations.

    Vital Sign - Oxygen Saturation

    • Measurement: Pulse oximeter.
    • Factors Affecting Oxygen Saturation: Hemoglobin levels, circulation, activity level.
    • Explanations: Low hemoglobin levels result in lower oxygen saturations. Impairment to circulation reduces oxygen transport to tissues.
    • Clinical Importance: Essential assessment in many medical conditions, such as shock, hypothermia or poor perfusion.

    Vital Signs - Pain Assessment

    • Classifications: Localized/referred pain, visceral/visceral pain, acute/chronic.
    • Pain Description: Intensity (mild/moderate/severe) and location.
    • Duration: Duration of pain (acute/chronic, short-term or long-term).
