    Study Notes

    Vital Signs Overview

    • Vital signs include temperature, pulse, blood pressure, respirations, and oxygen saturation.
    • These measurements are essential for assessing a patient's health status.

    Body Temperature

    • Defined as the balance between heat produced and lost by the body.
    • Core temperature, regulated by the hypothalamus, ranges from 36.0°C to 37.5°C.
    • Core temperatures can be measured via tympanic (ear) or rectal methods; surface temperatures through oral, axillary, or skin measurement.
    • Rectal temperatures are approximately 0.5°C higher than oral; axillary and tympanic are about 0.5°C lower.

    Assessing Temperature

    • Consider oral cavity conditions, ear issues, recent surgeries, and habits like smoking or drinking before measurement.
    • Proper thermometer cleaning: wipe dry with a tissue, shake to at least 35°C, and read at eye level.
    • Temperature measurement times vary: 3 minutes for oral, 2-3 minutes for rectal, and 10 minutes for axillary.
    • Oral temperature measurement is easily accessible, comfortable, provides accurate readings, and shows rapid core temperature changes.
    • Hyperthermia occurs above 37.5°C; hypothermia refers to temperatures below 36°C.

    Peripheral Pulses

    • Pulse is a throbbing sensation easily palpated at peripheral arteries (e.g., radial, carotid).
    • Characteristics include rate (60-100 beats per minute for adults) and rhythm, impacting heart and blood flow effectiveness.
    • Equipment required: watch with a second hand and gloves if needed.

    Assessing Pulse

    • Radial pulse is the most commonly used site; apical pulse preferred for infants and children under age 2.
    • Use first three fingers to palpate the artery, counting for 30 seconds, and multiply by 2 for rate per minute.
    • In case of irregularities, count for a complete minute.

    Respiration Assessment

    • Healthy adult respiratory rates range from 12 to 20 breaths per minute, characterized by depth and rhythm.
    • Avoid letting the patient know about the respiratory count to prevent altered breathing patterns.
    • Assess respirations immediately after pulse count, noting chest movements.

    Assessing Blood Pressure

    • Blood pressure measures the force of blood against arterial walls, consisting of systolic (highest pressure during heart contraction) and diastolic (lowest pressure during heart relaxation).
    • Measured in millimeters of mercury (mm Hg) using a stethoscope and sphygmomanometer.

    Blood Pressure Measurement Techniques

    • Position cuff 3-5 cm above the elbow with the cuff marker over the brachial artery.
    • Ensure snug cuff placement without obstruction from clothing.
    • Palpate the brachial or radial pulse while inflating the cuff for accurate application.
