Locked-in Guillain-Barré syndrome: 'my living nightmare'.

A 48-year-old man with severe Guillain-Barré syndrome suffered complete paralysis, and for 31 days could not communicate with the outside world, while remaining fully conscious. After recovery, he provided feedback on aspects of his care, such as mechanical ventilation, physical therapy, and communication. Conventional low tidal volume normocapnic ventilation induced ongoing and profound dyspnoea, occasionally relieved by modest increases in minute ventilation.
