Impact of Biphasic Cuirass Ventilation Compared to Non Invasive Ventilation in High Risk Extubations

We are planning on conducting a pilot study to assess if Biphasic cuirass ventilator is non inferior to Non invasive ventilation in high risk patients who are usually extubated to Non Invasive ventilation per current standard of care.

We will identify daily in our Medical Intensive care unit patients who have passed their spontaneous breathing trials and are being planned on being extubated to Non invasive ventilation per their treating Physician and will screen them for suitability and if so then one of our study team will approach patient and or their durable power of attorney and explain about our study and possible risks vs benefit and if they are agreeable will get a written consent and then they are randomized to either the Non invasive arm (per current standard of care) vs Biphasic cuirass ventilation arm (intervention arm).

We plan on assessing them per current standard of care with blood gas and other routine standard laboratory and or imaging. The subjects will not be compensated and they will be made aware of this upfront. Also their participation is completely voluntary and they will not get any additonal charge for taking part in the study. Assuming they tolerate the biphasic cuirass ventilator we anticipate them being on it anywere from 1-4 days.
