Neftaly Adult Respiratory Distress Syndrome (ARDS) Care
Introduction
Acute Respiratory Distress Syndrome (ARDS) is a severe inflammatory lung condition characterized by rapid onset of widespread alveolar damage, leading to respiratory failure. Effective management is critical to improving survival and reducing complications. Neftaly’s ARDS Care protocol outlines best practices for diagnosis, supportive care, and treatment in adults.
Objectives
- To promptly recognize and diagnose ARDS.
- To provide evidence-based ventilatory and supportive care.
- To monitor and manage complications.
- To optimize patient outcomes through multidisciplinary approaches.
1. Definition and Diagnosis
Berlin Criteria for ARDS:
- Timing: Within 1 week of a known clinical insult or new/worsening respiratory symptoms.
- Chest Imaging: Bilateral opacities not fully explained by effusions, lobar/lung collapse, or nodules.
- Origin of Edema: Respiratory failure not fully explained by cardiac failure or fluid overload.
- Oxygenation Impairment (on PEEP ≥5 cm H2O):
- Mild ARDS: PaO₂/FiO₂ 201–300 mm Hg
- Moderate ARDS: PaO₂/FiO₂ 101–200 mm Hg
- Severe ARDS: PaO₂/FiO₂ ≤100 mm Hg
2. Initial Assessment
- Identify and treat underlying cause (sepsis, pneumonia, trauma, aspiration).
- Assess oxygenation status and respiratory mechanics.
- Monitor vital signs, ABGs, chest imaging.
- Evaluate hemodynamics and organ function.
3. Respiratory Support
A. Oxygen Therapy
- Target SpO₂ 88–95% to avoid hyperoxia.
- High-flow nasal cannula or non-invasive ventilation (NIV) in selected mild cases.
B. Mechanical Ventilation
- Use lung-protective ventilation strategies:
- Low tidal volumes (4–6 mL/kg predicted body weight).
- Plateau pressure <30 cm H₂O.
- Moderate PEEP to maintain alveolar recruitment.
- Avoid volutrauma and barotrauma.
C. Prone Positioning
- Recommended in moderate to severe ARDS for ≥12–16 hours/day.
- Improves oxygenation and ventilation-perfusion matching.
D. Adjunct Therapies
- Neuromuscular blockade in early severe ARDS (48 hours).
- Conservative fluid management to avoid fluid overload.
- Consider ECMO in refractory hypoxemia where available.
4. Supportive Care
- Hemodynamic monitoring and support.
- Nutritional support via enteral feeding.
- Prevention of complications (ventilator-associated pneumonia, thromboembolism, stress ulcers).
- Sedation protocols to minimize delirium.
5. Monitoring and Reassessment
- Regular arterial blood gases and chest imaging.
- Monitor ventilator parameters and lung compliance.
- Assess for signs of recovery or deterioration.
- Adjust therapy accordingly.
6. Multidisciplinary Approach
- Collaboration among intensivists, respiratory therapists, nurses, nutritionists, and physiotherapists.
- Early mobilization as feasible.
- Family communication and psychological support.
Conclusion
Neftaly’s Adult Respiratory Distress Syndrome Care protocol promotes early recognition, lung-protective ventilation, and comprehensive supportive care to improve patient outcomes. Continuous monitoring and multidisciplinary management are vital in the care of ARDS patients.
