Study Notes
Blood Pressure Measurement Procedure
- Position patient comfortably; arm at heart level and palm facing up.
- Locate the radial pulse and identify the maximum inflation level (30 mmHg above where pulse stops).
- Place stethoscope over the brachial artery for accurate sound detection.
- Gradually deflate the cuff; listen for the first and last Korotkoff sounds to determine systolic and diastolic pressures.
- Always confirm readings by repeating after a brief wait, documenting results in fraction format (e.g., 117/69).
Blood Pressure Cuff Sizing
- Proper cuff size is critical for accurate measurements; width should be ¼ wider than the arm circumference.
- Larger cuffs are required for obese or muscular individuals; pediatric cuffs are available for children.
Hypertension and Blood Pressure Guidelines
- Hypertension defined as blood pressure consistently above 140/90 mmHg.
- Associated health risks include cardiovascular disease, stroke, kidney failure, and premature death.
- Treatment referrals vary by stage: Lifestyle changes for Normal and Elevated; consult a primary care provider for Stage I; medical referrals for Stage II.
- Emergency care recommended for readings of 180/120 mmHg or higher; clinic cutoff at 170/100 mmHg.
Pulse Characteristics
- Tachycardia: heart rate over 100 beats per minute; requires investigation.
- Bradycardia: heart rate below 50 beats per minute; can signify underlying issues.
- Factors increasing pulse: exercise, stimulants, emotional disturbances; decreasing factors include sleep and depressants.
Blood Pressure Fundamentals
- Blood pressure defined as the force exerted by blood on arterial walls.
- Systolic pressure (highest) occurs during heart contraction; diastolic pressure (lowest) occurs during relaxation.
- Pulse pressure calculated as the difference between systolic and diastolic pressures.
- Influencing factors: heartbeat force, peripheral resistance from vessel elasticity, and total blood volume.
Vital Signs Overview
- Essential for systemic evaluation and influence on dental treatment and planning.
- Patient should be seated upright and consent obtained prior to measurements.
Normal Body Temperature Ranges
- Average temperature for adults: 98.6°F; normal range is 97°F to 99°F.
- Older adults typically have a slightly lower average of 96.8°F.
- Children’s temperature varies by age, peaking at 99.4°F in the fourth year.
Temperature Variations and Influencing Factors
- Fever considered as temperature exceeding 99.5°F; hyperthermia over 104°F; hypothermia below 96°F.
- Body temperature affected by time of day, physical state (infections or trauma), and environmental factors.
Respiratory Assessment
- Normal adult respiratory rate ranges from 12 to 20 breaths per minute; higher for women.
- Children’s rates decrease over time; older adults show higher predictive value for complications.
- Tachypnea defined as a rate over 28 breaths per minute; bradypnea under 12 breaths.
Assessing Respiration
- Count chest rises for 30 seconds and multiply by two for rate.
- Note depth (shallow to deep), rhythm (regular to irregular), and quality (strong to labored).
- Document abnormal respiratory sounds during inspiration or expiration.
Pulse and Heart Rate Monitoring
- Adult resting pulse typically ranges from 60 to 100 beats per minute; varies with individual factors.
- Observe rhythm (regular or irregular) and strength (full or weak) while counting pulse.
- Children’s heart rate trends downward during childhood; closer observation for irregularities is essential.
