Brief summary
The trial is a trial comparing two modes of mechanical weaning in patients in ICU who are eligible for weaning from mechanical ventilation
Interventions
Patients who have been ventilated for > 48hrs and are suitable for spontaneous breathing will be randomised into either; Arm 1.Proportional Assist Ventilation ( PAV+) ventilation or Arm 2. Pressure Support ( PS) ventilation arm. Once assigned to either the PAV+arm or PS arm the patients will remain on their assigned mode of ventilation throughout the duration of their mechanical weaning. The duration of each participants' mechanical weaning will differ on a case by case basis. The PAV+ intervention differs from the standard PS treatment in that the software in the ventilator delivering PAV+ mode of ventilation measures resistance and elastance of the airway.Studies suggest this software may improve patient ventilator synchrony.
