What is Respiratory Distress?
![]() |
Physical examination findings in respiratory distress.
Children are more vulnerable due to:
· Smaller
airways
· Lower
lung reserve
· Immature
immune systems
Main Causes of Respiratory Distress in Children
Respiratory distress can arise from multiple systems:
1. Airway Problems
· Foreign
body obstruction
· Croup
· Epiglottitis
· Anaphylaxis
2. Lung & Chest Disorders
· Pneumonia
· Asthma
· Bronchiolitis
· Pneumothorax
3. Nervous System Issues
· Brain
injury
· Drug
overdose
· Increased
intracranial pressure
4. Neuromuscular Disorders
· Muscular
dystrophy
· Neuropathy
5. Other Systemic Causes
· Heart
failure
· Metabolic
acidosis
· Sepsis
Pathophysiology (How It Happens)
Respiratory distress occurs when one or more of these
processes fail:
· Ventilation
problem: Poor airflow in lungs
· Perfusion
problem: Blood not reaching lungs properly
· Diffusion
problem: Oxygen can't pass into blood
This leads to:
· Hypoxemia
(low oxygen)
· Hypercapnia
(high CO₂)
Signs & Symptoms (Early vs Severe) Early Signs
· Fast
breathing (tachypnea)
· Nasal
flaring
· Mild
chest retractions
· Wheezing
Severe Signs (Emergency )
· Cyanosis
(blue lips/skin)
· Grunting
· Altered
consciousness
· Paradoxical
breathing

Clinical Examination
Vital Signs
· Respiratory
rate
· Oxygen
saturation (pulse oximetry)
· Heart
rate
Key Findings
· Stridor:
Upper airway obstruction
· Wheezing:
Lower airway problem
· Crackles:
Fluid in lungs (pneumonia)
· Retractions:
Increased breathing effort
Diagnosis & Tests
Imaging
· Chest
X-ray → pneumonia, pneumothorax
· Neck
X-ray → croup (“steeple sign”)
Blood Tests
· Arterial
blood gas (ABG)
· CBC
(infection detection)
· Electrolytes
Advanced Tests
· CT
scan
· MRI
· Ventilation-perfusion
scan
Emergency Management (Life-Saving Steps)
Step 1: ABC Approach
· Airway:
Clear obstruction
· Breathing:
Provide oxygen
· Circulation:
Stabilize blood flow
Step 2: Immediate Interventions
· Oxygen
therapy
· IV
fluids (if dehydration)
· Antipyretics
(if fever)
· Suction
airway
Step 3: Advanced Treatment
· Nebulization
(asthma)
· Antibiotics
(infection)
· Mechanical
ventilation (severe cases)
When to Seek Emergency Help
Call emergency services if a child has:
· Difficulty
speaking or crying
· Blue
lips or face
· Severe
chest retractions
· Loss
of consciousness
