What is a key concern for patients with Guillain-Barré syndrome related to respiratory function?

Patients with Guillain-Barré syndrome often experience progressive muscle weakness that can affect the respiratory muscles. One of the key concerns for these patients is the ability to clear secretions effectively. This syndrome can lead to weakness in the diaphragm and intercostal muscles, which are essential for proper ventilation and secretion clearance. As respiratory muscle strength diminishes, patients may struggle to cough effectively, increasing the risk of retained secretions in the airways. Retained secretions can lead to infection and further compromise respiratory function, making it vital to monitor and manage this aspect of care closely.

While reduced lung capacity could be a concern due to muscle weakness, the immediate threat to respiratory function lies in secretion management, making it a critical focus in the care of patients with this syndrome.
