Scientific title
A prospective study to systematically assess the nature and time course of sleep disordered breathing and respiratory failure in patients with motor neurone disease and to study the effects of auto-bilevel positive airway pressure [BiPAP] ( with variable expiratory positive airway pressure[EPAP]) vs. standard bilevel positive airway pressure [BiPAP]- spontaneous/timed (S/T) mode , in patients requiring non invasive ventilation(NIV) as per current guidelines

Description of intervention(s) / exposure
This is an prospective observational study with a phase II randomised controlled arm. We have previously demonstrated( retrospective observational study) that patients with motor neurone disease( MND) develop a spectrum of various types of sleep disordered breathing.
Aims:
1. A prospective study of 40 patients to delineate the nature and time course of sleep disordered breathing in MND patients referred to the Repatriation General Hospital MND clinic for assessment.
2. Detailed sleep studies of Auto BiPAP ( using BiPAP A 40 AVAPS AE mode AE mode with auto pressure support, auto EPAP and auto back-up rate) vs. currently recommended BiPAP-S/T using a cross-over randomized 2 overnight study design ( consecutive nights), to assess the acute effects of each treatment in patients with respiratory failure, followed by randomization to one of the two treatments and clinical follow-up for 6 months ( minimum).
This part of the study will include all the patients who meet the criteria for NIV as per the current guidelines. There is no washout period between the two nights, for the cross-over trial.
