Who this trial is looking for
This trial is looking for adult patients who have recently had major abdominal surgery and need breathing support in the ICU. Participants will be monitored to see how they adapt to different levels of breathing assistance.
Are You a Good Fit for This Trial?
You may be able to join if
- I am at least 18 years old
- I have had major abdominal surgery recently
- I am receiving breathing support with a machine
- I have been on breathing support for more than 48 hours
- I am stable and not expected to be taken off the machine in 6 hours
- My breathing rate is less than 35 breaths per minute
- My oxygen level is at least 90%
- My heart rate is less than 140 beats per minute
You may not be able to join if
- I have a known neuromuscular disease affecting my breathing
- I am unstable and need more support to maintain my blood pressure
- I have severe breathing failure requiring high pressure support
- I am deeply sedated and not alert
- I have a history of chronic obstructive pulmonary disease
- I have a history of another obstructive lung disease

About This Trial
This physiological observational study will assess respiratory drive and inspiratory effort across varying levels of pressure support ventilation (PSV) in adult surgical ICU (SICU) patients after major abdominal surgery. By using non-invasive bedside indices (airway occlusion pressure at 100 ms after the onset of inspiration \[P0.1\], maximum negative occlusion pressure \[Pocc\], and pressure musc…
