Brief Summary:
We will investigate whether measurement of the change in thickness of the diaphragm during the respiratory cycle by ultrasound can predict extubation success in a 48 hour window. We will also asses whether this is only possible on low levels of pressure support as has been shown previously, or if this technique retains its predictive power at higher levels of pressure support.

Group/Cohort Intervention/treatment
Main Cohort
all patients enrolled will have an ultrasound of their diaphragm performed once they are on a pressure support trial. Intervention: Diaphragm Ultrasound
Procedure: Diaphragm Ultrasound
Once on a pressure support weaning trial, enrolled subjects will have an ultrasound of their right hemidiaphragm performed on three levels of pressure support: 15/5 10/5 and 5/5

Primary Outcome Measures :
  1. Extubation Success [ Time Frame: 48 hours ]
    Discontinuation from mechanical ventilation in 48 hours from ultrasound

Secondary Outcome Measures :
  1. Re-intubation [ Time Frame: 48 hours from removal of ventilatory support ]
    Reinstitution of mechanical ventilation within 48 hours of extubation
