How do quadriplegics breath?

Quadriplegics can breathe independently if their diaphragm and intercostal muscles are functioning, which is often the case if their spinal cord injury is incomplete. However, those with complete quadriplegia may have impaired respiratory function and might rely on mechanical ventilation or assistive devices to aid breathing. In some cases, individuals may use techniques like adaptive coughing to help clear their airways. Rehabilitation and respiratory therapy can also play a crucial role in improving respiratory function.
