Acute Respiratory Distress Syndrome (ARDS)

Sudden, Severe Lung Failure Requiring Emergency Care

Acute Respiratory Distress Syndrome (ARDS) is a life-threatening condition where the lungs rapidly fill with fluid due to severe inflammation, leading to critically low oxygen levels. It usually occurs in ICU settings due to severe infections, trauma, or other critical illnesses.

Immediate ICU care is critical for survival.

Understanding

What is Acute Respiratory Distress Syndrome?

ARDS occurs when:

  • Severe inflammation damages lung membranes
  • Fluid leaks into air sacs (alveoli)
  • Oxygen exchange becomes severely impaired

This leads to:

  • Low blood oxygen levels
  • Respiratory failure
  • Need for ventilator support
Warning Signs

Risk Factors

Causes & Risk Factors

Common Causes
  • Severe pneumonia
  • Sepsis (blood infection)
  • Trauma or injury
  • Aspiration (inhaling stomach contents)
Risk Factors
  • ICU patients
  • Major surgery
  • Severe infections
  • Chronic illness
Progression

Disease Progression

Acute Phase Rapid inflammation
Exudative Phase Fluid accumulation
Fibrotic Phase Lung scarring
End Stage Transplant needed

Acute Phase

Rapid lung inflammation

Oxygen levels drop

ICU Admission

Exudative Phase

Fluid accumulation in lungs

Ventilation Support

Fibrotic Phase

Lung scarring develops

Severe cases only

ECMO Consideration

End Stage Lung Disease

Persistent lung damage

Transplant required (rare)

Lung Transplant
Testing

Diagnosis & Tests

Chest X-ray / CT scan
Arterial blood gas (ABG)
Oxygen saturation (SpO2)
Clinical ICU assessment

Critical illness requires close monitoring

Assess your lung function risk

Management

Treatment Options (Before Transplant)

1. ICU Support
  • Mechanical ventilation
  • Oxygen therapy
2. Treat Underlying Cause
  • Antibiotics (infection)
  • Manage trauma/sepsis
3. Advanced Support
  • Prone positioning
  • ECMO (in severe cases)

When is Lung Transplant Needed?

Severe irreversible lung damage

Failure to recover after ICU care

Chronic respiratory failure develops

Early ICU Intervention Saves Lives

Timely treatment significantly improves survival

Important Consideration: Emergency Condition

• Rapid onset • Requires ICU care • Outcome depends on early management

ICU Management vs Transplant
ICU Management

Stage: Acute • Goal: Restore lung function • Outcome: Often reversible

Lung Transplant

Stage: Severe irreversible • Goal: Replace lungs • Outcome: Rare but life-saving
