Intubation for ARDS
- For suspected severe ARDS, intubate the patient for mechanical ventilation.
- Lung-protective ventilation avoids over-distending alveoli and causing further damage.
Lung-Protective Ventilation
- Lung-protective ventilation uses low tidal volumes (6-8 cc/kg of ideal body weight) to minimize alveoli overdistension.
- Permissive hypercapnia (allowing slightly elevated CO2) is acceptable to protect the lungs.
PEEP in ARDS
- PEEP (positive end-expiratory pressure) keeps alveoli open at the end of exhalation, preventing collapse and atelectrauma.
- Optimal PEEP improves oxygenation and lung mechanics by increasing compliance.
