In the hours before diagnosis, there was increased clinical intervention, including reintubation; this was less so in those diagnosed by transillumination. The study did not elucidate whether such interventions caused the pneumothorax or were secondary to a failure to diagnose it.<\/jats:p>\n                  <jats:p>\n                     <jats:boxed-text position=\"float\">\n                        <jats:sec>\n                           <jats:title>Key messages<\/jats:title>\n                           <jats:list list-type=\"simple\">\n                              <jats:list-item>\n                                 <jats:p>Brief inadvertent overventilation was not associated with pneumothoraces<\/jats:p>\n                              <\/jats:list-item>\n                              <jats:list-item>\n                                 <jats:p>There was a cluster of clinical procedures before the diagnosis of a pneumothorax.
