RT Journal Article SR Electronic T1 Cerebral air embolism complicating bilevel positive airway pressure therapy JF European Respiratory Journal JO Eur Respir J FD European Respiratory Society SP 235 OP 237 DO 10.1183/09031936.98.12010235 VO 12 IS 1 A1 SC Hung A1 HC Hsu A1 SC Chang YR 1998 UL http://erj.ersjournals.com/content/12/1/235.abstract AB A 13 yr old male with acute lymphoblastic leukaemia who received bilevel positive airway pressure ventilation via a face mask for post-transplant pneumonitis developed subcutaneous emphysema, radiographic evidence of pulmonary interstitial emphysema, pneumomediastinum and 6 h later, right hemiparesis and focal livedo reticularis. This case illustrates that severe barotrauma may complicate noninvasive bilevel positive airway pressure ventilation.
