Study Notes
Vital Sign Significance
- Vital signs are objective measurements of the body's basic functions.
- They include temperature, blood pressure, pulse, respiratory rate, and oxygen saturation.
- Normal ranges vary based on factors like age, BMI, and gender.
- Vital signs monitor patient health and detect deterioration, especially in acute care.
Assessment Techniques & Equipment
Temperature
- Oral: Convenient, commonly used, electronic thermometers (20-30 seconds).
- Rectal: Most accurate, invasive, patient positioned in left lateral decubitus.
- Tympanic: Noninvasive, quick, for adults, pull ear up and back; children under 3, pull ear down and back.
- Temporal Artery: Sliding probe across forehead/behind ear, less accurate.
Pulse
- Measures the heart's pumping action, felt as a pressure wave.
- Palpate radial pulse using first three fingers at the wrist.
- Count beats for 30 seconds (multiply by 2 for regular rhythm), 60 seconds (for irregular rhythm).
- Assess rate, rhythm, and force. Auscultate heart sounds if irregularities are detected.
- Normal rates vary by age and gender (faster in infancy/childhood, slightly faster in females after puberty).
Respiration Rate
- Normal breathing is relaxed, regular, automatic, and silent.
- Count for 60 seconds for accuracy.
- Document rate per minute and breathing characteristics.
Blood Pressure
- Force of blood against vessel walls, changes with cardiac cycle.
- Systolic: Maximum pressure during contraction.
- Diastolic: Resting pressure between contractions.
- Pulse Pressure: Difference between systolic and diastolic.
- Mean Arterial Pressure (MAP): Average pressure forcing blood into tissues (MAP > 60 mmHg needed for adequate perfusion).
- Normal readings vary based on age, sex, race, social determinants, daily patterns, weight, exercise, emotions, and stress.
- Noninvasive: Electric devices, measures BP, MAP, and pulse rate.
- Manual: Sphygmomanometer and stethoscope, able to assess pulse quality.
- Proper technique crucial for accurate readings including a 5-minute rest, sitting position, uncrossed legs, and arms at heart level, correct cuff size.
- Document extremity used, position, and cuff size for consistency.
- Normal BP < 120 mmHg / < 80 mmHg
Oxygen Saturation (SpO2)
- Noninvasive, measures arterial blood oxygen saturation.
- Measured on fingers, forehead, nose, or toes (adults); hands, thumbs, or feet (infants).
- Normal range is 97% to 99%.
Doppler
- Used to measure blood flow through vessels.
- Detects and amplifies changes in sound frequencies as blood flows and ebbs.
- Useful for locating peripheral pulse sites.
Abnormal Vital Signs
- Bradycardia: Heart rate < 60 bpm
- Tachycardia: Heart rate > 100 bpm
- Tachypnea: Respiratory rate > 25 breaths/min
- Bradypnea: Respiratory rate < 12 breaths/min
- Hypertension: Systolic > 140 mmHg or diastolic > 90 mmHg
- Hypotension: Low blood pressure, 20 mmHg decrease or diastolic drop >10 mmHg in a standing position.
Orthostatic Vital Signs
- Serial measurements of pulse and blood pressure.
- Useful in volume depletion suspicion, known hypertension/antihypertensive medication use, syncope/near-syncope reports.
- Procedure:
- Patient rests supine 3-5 minutes, measure BP and pulse.
- Have patient sit, measure BP and pulse.
- Have patient stand, measure BP and pulse.
- After standing 3 minutes, measure BP and pulse.
- Normally, a slight decrease in reading when changing from supine to standing is expected.

Description
This quiz covers the importance and measurement techniques of vital signs such as temperature, pulse, respiration rate, and blood pressure. Understanding these metrics is essential for patient health monitoring and detecting potential deterioration. Assess different methods like oral, rectal, tympanic, and temporal artery temperature measurements.
