Acute Respiratory Failure C0264490
A medical emergency where the lungs cannot provide enough oxygen to the body or remove enough carbon dioxide. Can affect anyone with severe lung disease, injury, or organ failure. Treatment often involves supplemental oxygen or mechanical breathing support.

Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Oxygen Therapy and Respiratory Support
Administration of supplemental oxygen via non-invasive methods (high-flow nasal cannula, CPAP, BiPAP) to correct hypoxemia. Escalation to invasive mechanical ventilation when non-invasive support fails or respiratory arrest is imminent.
Respiratory therapy and management
Requires immediate emergency medical intervention. Do not delay treatment.
Treatment of Underlying Cause
Etiology-specific therapy such as bronchodilators for COPD exacerbation, diuretics for pulmonary edema, antibiotics for pneumonia, or specific reversal agents for toxic causes. Addressing the precipitating factor is essential for respiratory recovery.
Additional treatment options
Respiratory Physiotherapy
Chest physiotherapy techniques including percussion, vibration, and directed coughing to mobilize secretions and improve airway clearance. Breathing exercises help strengthen respiratory muscles and prevent complications of prolonged ventilation.
physical_therapyContinuous Cardiorespiratory Monitoring
Continuous telemetry and pulse oximetry surveillance with regular arterial blood gas analysis to assess response to therapy and detect deterioration early. Serves as the foundation for safe management of respiratory failure.
monitoringNutritional Optimization
Adequate caloric and protein intake to prevent malnutrition and respiratory muscle wasting. Nutritional support helps maintain ventilatory drive and immune function critical for recovery from respiratory failure.
dietaryWhen to seek medical help
Recognize when you need immediate medical attention.
Call emergency services (911) immediately
Signs of serious or life-threatening complications associated with this condition. Immediate medical evaluation is required.
Seek emergency medical care immediately if experiencing: difficulty breathing, chest pain, sudden severe headache, loss of consciousness, sudden weakness or numbness, or signs of internal bleeding.
