Respiratory Care for Atelectasis

Diagnosis and Assessment

High-resolution CT (HRCT) is preferred over chest radiography for accurate diagnosis and assessment of extent, including inspiratory prone images and supine end-expiratory imaging, as recommended by the American College of Rheumatology 1
Pulmonary Function Tests (PFTs) provide complementary information about physiologic impact, including spirometry, lung volumes, and DLCO, as suggested by the American Thoracic Society 1
Abdominal CT and CT chest should be considered to rule out intra-abdominal complications and characterize the extent of aspiration and consolidation, as recommended by the World Journal of Emergency Surgery guidelines 2, 3

Non-invasive positive pressure ventilation (NIPPV) or continuous positive airway pressure (CPAP) should be implemented immediately for hypoxemic patients with aspiration and consolidation, using a CPAP level of 8 cm H₂O for at least 8-12 hours, as recommended by the World Journal of Emergency Surgery guidelines 3
Controlled oxygen therapy should be used to maintain SpO₂ ≥94% with the lowest possible FiO₂, avoiding high FiO₂ (>0.8) during emergence from anesthesia, as recommended by the European Respiratory Society and the British Journal of Anaesthesia 4, 5
Non-invasive ventilation (NIV) or CPAP can be used if conservative measures do not improve oxygenation, with a CPAP level of 7.5-10 cmH₂O, as recommended by the European Respiratory Society 4

A passive leg raise (PLR) test should be performed to determine fluid responsiveness before administering IV fluids, as suggested by the British Journal of Anaesthesia guidelines 6
If the PLR test is positive, a crystalloid fluid bolus should be administered, and if negative, vasopressor therapy (norepinephrine) should be initiated, as recommended by the British Journal of Anaesthesia guidelines 6
Indiscriminate fluid administration without assessing fluid responsiveness can worsen respiratory status in patients with aspiration pneumonia, as warned by the British Journal of Anaesthesia guidelines 6

Bronchoscopy allows for mechanical removal of sloughed bronchial epithelium and mucus plugs, preventing airway obstruction, as recommended by the British Thoracic Society 7
Decortication may be beneficial for extensive pleural fibrosis (pachypleuritis) causing ventilatory failure, as stated by the American Thoracic Society 8
Consider surgical intervention for rounded atelectasis presenting as a mass-like lesion that doesn't respond to conservative measures, as recommended by the American Thoracic Society 8
Flexible bronchoscopy can be used to restore airway patency by removing mucus plugs or blood clots causing atelectasis, and is indicated for persistent atelectasis despite conservative measures 9

Airway suctioning under direct vision using laryngoscope is recommended to remove secretions, as suggested by the Association of Anaesthetists of Great Britain and Ireland 10
Positive end-expiratory pressure (PEEP) ventilation, positive expiratory pressure (PEP) devices, and high-frequency oscillation devices can assist in secretion clearance, as recommended by the Intensive Care Medicine society and the Chest society 11, 12

Careful measurement of respiratory rate and heart rate, as well as continuous monitoring of oxygen saturation, is recommended for hypoxemic patients, as suggested by the British Thoracic Society 13
Arterial blood gas analysis should be considered to evaluate oxygenation and ventilation status, as recommended by the British Thoracic Society and the European Respiratory Society 13, 14
Vaccinations against influenza and pneumococcus should be administered to patients with chronic conditions and atelectasis, as recommended by the American Thoracic Society 15
Early mobilization and ambulation, as well as postural drainage techniques, can help reduce pulmonary complications, as recommended by the Intensive Care Medicine society and the Chest society 11, 12

Implementing a structured protocol of multimodal respiratory physiotherapy can reduce the rate of postoperative pulmonary complications, improving clinical outcomes in patients with postoperative atelectasis and pleural effusion, as recommended by the American College of Chest Physicians 16
Recruitment maneuvers and respiratory muscle strength training may be beneficial for patients with atelectasis, as recommended by the American Thoracic Society and the European Respiratory Review 17, 18
Locoregional analgesia techniques and patient-controlled analgesia (PCA) with opioids can be used for pain management, as recommended by the American Society of Anesthesiologists 16
