  1. Data are presented as numbers (%), means ± standard deviations or medians (interquartile ranges)
  2. Abbreviations: PACU: postanesthesia care unit. BAL: bronchoalveolar lavage
  3. a Cardiovascular collapse: clinical evidence of inadequate perfusion
  4. b Cardiac arrest: absence of pulse and loss of heart function
  5. c The duration of bronchoscopy was the duration between the insertion of the bronchoscope and the removal of the bronchoscope
