Initial Treatment for Basilar Atelectasis
The initial treatment for basilar atelectasis should focus on chest physiotherapy including postural drainage, percussion, and vibration techniques to mobilize secretions and promote airway clearance. 1
Primary Treatment Approaches
- Chest physiotherapy techniques (postural drainage, percussion, vibration) are the first-line treatment for mobilizing secretions and promoting airway clearance in basilar atelectasis 1, 2
- Breathing exercises including forced expiration technique (huffing) are effective for increasing airway clearance and should be taught to patients for self-management 1
- Proper patient positioning with head elevated at least 30 degrees improves lung expansion and prevents further atelectasis 1, 2
- Early mobilization and physical activity should be encouraged as immobility contributes to deterioration in lung function 2
Breathing Exercises and Lung Expansion
- Incentive spirometry should be prescribed to encourage deep breathing and maximal inspiration, helping to prevent and treat atelectasis 1, 2
- Respiratory muscle strength training improves ventilatory patterns, lung volumes, and respiratory muscle strength 1, 2
- For mechanically ventilated patients, alveolar recruitment maneuvers involving transient elevation of airway pressures (30-40 cm H2O for 25-30 seconds) effectively re-expand collapsed lung tissue 1, 3
- Positive expiratory pressure (PEP) therapy can be used to open airways while promoting removal of secretions 2
Oxygen Therapy Considerations
- High FiO2 (>0.8) should be avoided during recovery as it can worsen atelectasis formation 1, 3
- If supplemental oxygen is needed, FiO2 <0.4 should be used to reduce the risk of worsening atelectasis 2, 3
- Supplemental oxygen should not be relied upon solely without addressing the mechanical aspects of atelectasis 1, 3
Advanced Interventions for Persistent Cases
- Flexible bronchoscopy is indicated for persistent cases with mucous plugging that fail to respond to conservative measures 1, 2
- Bronchoscopy should be performed for direct visualization and removal of obstructing secretions in cases of persistent mucous plugs causing atelectasis 1
- Nebulized hypertonic saline may be considered as an adjunct to airway clearance in persistent cases 2, 3
Special Considerations
- Cough assist devices may improve forced vital capacity and peak cough flow in patients with neuromuscular weakness contributing to atelectasis 1, 2
- Suctioning may be necessary when cough is inadequate to clear secretions, but routine deep suctioning should be avoided as it may be associated with longer recovery time 1
- For patients with recurrent respiratory infections and atelectasis, consideration should be given to evaluating for underlying causes such as gastroesophageal reflux disease or aspiration 2
Common Pitfalls to Avoid
- Performing airway clearance techniques without proper instruction reduces effectiveness 1, 2
- Applying positive end-expiratory pressure (PEEP) without first performing recruitment maneuvers is less effective, as PEEP maintains but does not restore functional residual capacity 2, 3
- Relying solely on supplemental oxygen without addressing the mechanical aspects of atelectasis 1
- Using high FiO2 (>0.8) during recovery can worsen atelectasis formation 1, 3
