Module 1: General Assessment & Vital Signs
Master APGAR scoring, vital sign interpretation, and general newborn appearance assessment
Welcome to Module 1!
In this module, you’ll learn the fundamentals of newborn assessment. We’ll start with APGAR scoring, progress to vital sign interpretation, and develop skills in assessing overall newborn appearance. These are critical foundational skills for safe newborn care.
Learning Objectives
By the end of this module, you will be able to:
- ✅ Accurately calculate APGAR scores and interpret their clinical significance
- ✅ Recognize normal vs abnormal vital signs in term and preterm newborns
- ✅ Systematically assess general newborn appearance
- ✅ Identify concerning features requiring further evaluation
- ✅ Communicate findings appropriately to families
Lesson 1: The APGAR Score
History and Purpose
The APGAR score, developed by Dr. Virginia Apgar in 1952, provides a quick, standardized assessment of newborn transition immediately after birth. It helps identify infants who need resuscitation or special attention.
The Five Components
Appearance (color) Pulse (heart rate) Grimace (reflex irritability) Activity (muscle tone) Respiration
Each component is scored 0, 1, or 2, for a maximum total score of 10.
Scoring Details
| Component | 0 | 1 | 2 |
|---|---|---|---|
| Appearance | Blue/pale all over | Body pink, extremities blue (acrocyanosis) | Completely pink |
| Pulse | Absent | <100 bpm | >100 bpm |
| Grimace | No response | Grimace/feeble cry | Sneeze/cough/vigorous cry |
| Activity | Limp/flaccid | Some flexion | Active motion, good tone |
| Respiration | Absent | Slow, irregular, weak cry | Good crying, regular breathing |
Interpretation
- 7-10: Generally normal - infant is transitioning well
- 4-6: Moderately abnormal - infant may need intervention (stimulation, oxygen, positive pressure ventilation)
- 0-3: Severely abnormal - infant needs immediate resuscitation
Important Notes
- Scores are assessed at 1 minute and 5 minutes after birth
- If 5-minute score is <7, continue scoring every 5 minutes up to 20 minutes
- The 1-minute score indicates immediate condition and need for resuscitation
- The 5-minute score is a better predictor of neurological outcome
- APGAR scores should not delay resuscitation - if infant needs help, start immediately
Clinical Pearls
- Acrocyanosis (blue hands/feet) is common in the first 24 hours - this is normal!
- Healthy preterm infants may have slightly lower scores due to immaturity
- Medications during labor (magnesium, opioids) can affect scores
- Don’t subtract points for issues that are normal (e.g., acrocyanosis in a vigorous infant)

Exercise 1.1: APGAR Scoring from Clinical Scenarios
Let’s practice! You’ll be given detailed descriptions of newborns immediately after birth. Your job is to calculate APGAR scores and interpret them.
Exercise 1.1: APGAR Scoring
🎯 Your Challenge
Review the clinical scenarios describing newborns at 1 and 5 minutes after birth. Calculate APGAR scores for each time point and explain the clinical significance and next steps.

Lesson 2: Newborn Vital Signs
Normal Ranges for Term Newborns
Understanding normal vital sign ranges is crucial for identifying sick infants.
Heart Rate
- Normal: 120-160 bpm at rest
- Can increase to 180 bpm when crying or active
- During sleep: may drop to 100 bpm
- Concerning: <100 bpm (bradycardia) or persistent >180 bpm (tachycardia)
Respiratory Rate
- Normal: 30-60 breaths per minute
- Periodic breathing is normal (brief pauses <10 seconds followed by rapid breathing)
- Concerning: >60 consistently (tachypnea) or apnea >20 seconds
Temperature
- Normal: 36.5-37.5°C (97.7-99.5°F) axillary
- Hypothermia: <36.5°C
- Fever: >38.0°C (requires evaluation for sepsis in newborns)
Blood Pressure (varies by birthweight and gestational age)
- Term newborn average: 65-75 systolic / 40-50 diastolic
- Typically not routinely measured unless concerns
Oxygen Saturation
- Normal: ≥95% in room air after first few hours of life
- Right hand (pre-ductal) and foot (post-ductal) should be within 3% of each other
Red Flags in Vital Signs
- Persistent tachycardia or bradycardia
- Tachypnea, especially with increased work of breathing
- Fever or hypothermia
- Oxygen saturation <95% or significant pre-ductal/post-ductal difference
Special Considerations
Preterm Infants: May have different normal ranges based on gestational age First Hours of Life: Transitional period - some variation expected Crying/Feeding: Temporarily affects heart rate and respiratory rate
Exercise 1.2: Vital Signs - Normal vs Abnormal
Practice identifying concerning vital signs and determining appropriate actions.
Exercise 1.2: Vital Signs Assessment
🎯 Your Challenge
Review vital signs from multiple newborn cases. Identify which are normal vs abnormal, explain the clinical significance, and recommend appropriate next steps.

Lesson 3: General Appearance Assessment
The “Eyeball Test”
Experienced clinicians often say they can tell if a baby is sick just by looking. This “eyeball test” involves systematic assessment of:
Components of General Appearance
Color
- Pink and well-perfused = good
- Central cyanosis (blue tongue/mucous membranes) = concerning
- Acrocyanosis (blue hands/feet only) = normal in first 24-48 hours
- Pallor = possible anemia, poor perfusion
- Jaundice = assess level and timing
Activity and Tone
- Alert when awake, easily consolable = reassuring
- Vigorous cry and movement = good
- Lethargic, poor response to stimulation = concerning
- Hypotonic (“floppy”) or hypertonic (stiff) = abnormal
Respiratory Effort
- Quiet, easy breathing = normal
- Tachypnea, retractions, grunting, flaring = distress
Symmetry and Proportions
- Symmetric face, body, limbs = normal
- Asymmetry may indicate birth trauma or congenital anomaly
- Dysmorphic features may suggest genetic syndrome
State and Behavior
- Appropriate sleep-wake cycles
- Responsive to stimuli
- Consolable when crying
- Interested in feeding
Red Flags in General Appearance
- Appears ill or “just doesn’t look right”
- Lethargic or difficult to arouse
- Inconsolable crying or high-pitched cry
- Poor feeding, weak suck
- Central cyanosis
- Significant respiratory distress
- Marked dysmorphic features

Module 1 Complete! 🎉
Congratulations on completing Module 1! You’ve learned the fundamentals of newborn assessment:
✅ APGAR scoring and interpretation ✅ Normal vs abnormal vital signs in newborns ✅ Systematic general appearance assessment ✅ Identifying red flags requiring further evaluation
Key Takeaways
- APGAR scores guide immediate newborn care - but never delay resuscitation
- Know your normal ranges - vital signs vary by age and state
- Trust your clinical gestalt - if a baby “doesn’t look right,” investigate
- Context matters - consider gestational age, maternal factors, and time since birth
- Safety first - when in doubt, err on the side of caution with newborns
What’s Next?
In Module 2, you’ll learn focused examination of the head, eyes, ears, nose, and throat. You’ll practice identifying cranial molding, assessing the red reflex, and differentiating normal oral findings from those requiring intervention.
