Study Arms:
- Positive end-expiratory pressure (PEEP) level changes (Type: EXPERIMENTAL): Sequential changes in PEEP level within range of 4-8 cm H2O followed by measurement of V/Q mismatch at each level.

Based on this trial design, predict the completion outcome and termination type (if applicable).
