IS helps in better oxygenation in first 24 hours after open heart surgery, and ensures good inspiratory effort by the patients, which in turn results in decreased incidence of atelectatic
The lesion was producing a significant mass effect in the thorax, as both the left lower lobe and a significant portion of the left upper lobe of the lung were completely atelectatic
Thoracic CT scans revealed mediastinal lymphadenopathy, bilateral emphysematous areas, and the right upper lobe had bronchiectatic, fibrotic and atelectatic
Effect of intrapleural pressure on pulmonary shunt through atelectatic
Mechanism of decreased blood flow to atelectatic
In patients without pleurotomy, as the hematoma volume is less, increase of the atelectatic
lung segments will be limited.
Manual hyperinflation might open collateral channels within the lungs, which could theoretically recruit atelectatic
lung regions and facilitate secretion mobilisation (Anderson et al 1979).
In expiration the surfactant molecules pack together so tightly that the surface tension normally generated at a liquid-gas interface shrinks to ~0 mN/m eliminating the atelectatic
force at end expiration.
The alveoli in half of the specimens were atelectatic
THEORY: High frequency puffs of air are believed to open atelectatic
alveoli and deliver air behind mucus plugs, helping to dislodge them.
Immature lungs become progressively atelectatic
due to alveolar collapse resulting from the deficiency in surfactant, causing respiratory distress.
Any PPCs like development of pleural effusion, atelectatic
lung on Chest X-Ray, lobar lung collapse or requirement of NIV every 4-6 hourly during the first 48 hours were also noted.
