title: A portable electronic 'calling device' as an aid to 'weaning' ventilator-dependent tetraplegic patients from intermittent positive pressure ventilation.
abstract: An electronic calling device has been developed. It is easily portable and can be operated by the severely paralysed tetraplegic patient in order to attract attention. The patient can operate the sensor either during artificial ventilation or when breathing spontaneously via the tracheostomy tube at a stage prior to the insertion of a speaking tube.
