INTRODUCTION: Conventional @entity386 testing in @entity1 with severe @entity519 or @entity1344 with removal from the ventilator support is unsafe. We describe an alternative approach to @entity386 testing, which may be used in @entity1 with @entity519 unable to undergo conventional @entity386 testing. METHODS: Case Report. A 42-year-old @entity1 had a severe @entity131 resulting in @entity2657 and @entity510 with @entity3976 . His presentation was complicated by @entity1576 from pulmonary contusions and @entity548 . On hospital day 2, the @entity1 lost brain stem reflexes. @entity1620 testing with conventional @entity386 testing was attempted but aborted due to @entity519 . RESULTS: A modified @entity386 test was applied, which had been approved by appropriate hospital committees including critical care operations, ethics, and the @entity1620 protocol council. Minute ventilation was gradually decreased by >= 50% to attain a PaCo 2 level >= 20 mm Hg above baseline. The ventilation mode was then switched from volume control to continuous positive airway pressure while observing the @entity1 for signs of respiration for a duration of 60 seconds. CONCLUSION: The modified @entity386 test does not require circuit disconnection and can be successfully applied to determine @entity1620 without compromising safety in high-risk @entity1 having severe @entity519 .
