When may respiratory care be necessary for scoliosis?

Respiratory care may become necessary when the Cobb angle exceeds 40 degrees due to the increased risk of respiratory compromise associated with scoliosis at this severity. Scoliosis can lead to significant alterations in the thoracic cavity's structure, which may affect lung capacity and function. As the angle increases, the curvature of the spine can compress the lungs and diminish their ability to expand fully during respiration.

In patients with a Cobb angle exceeding 40 degrees, pulmonary function tests often show a decline in vital capacity and forced expiratory volume, indicating that the thoracic deformity is impacting respiratory function. Consequently, respiratory care interventions might be required to optimize breathing, prevent complications, and ensure adequate oxygenation in individuals with severe scoliosis.

While lower angles may not typically necessitate respiratory support, the critical threshold for intervention aligns with the 40-degree mark, emphasizing the importance of monitoring and managing respiratory issues in patients with significant scoliosis.
