A 62-year-old inpatient undergoing a portable chest radiograph suddenly develops stridor and hypotension after a latex glove change, the radiographer suspects anaphylaxis, gives no medication beyond scope, calls the rapid response team, and captures an image showing a new large tension pneumothorax. The nurse asks what to report. Which critical finding communication should the radiographer use to alert the health care team?

Correct practice requires immediate direct closed-loop verbal report to the nurse and provider of both suspected latex anaphylaxis and the new large tension pneumothorax because stridor with hypotension and tension physiology are imminently life-threatening and demand parallel resuscitation and decompression planning, and closed-loop exchange confirms receipt while the radiographer reports observations without drugs beyond scope. Entering a STAT electronic critical result with callback is standard for documented acknowledgment of critical imaging findings, but it fails on synchrony because an unstable patient cannot wait for asynchronous review. Reporting only the pneumothorax with closed-loop technique shows excellent imaging communication, but it fails on completeness because omitting latex-associated stridor and hypotension withholds the trigger needed for resuscitation and exposure control. Giving an immediate verbal report of suspected anaphylaxis while holding the pneumothorax for final radiologist confirmation escalates deterioration appropriately, but it fails on responsibility because a newly seen large tension pneumothorax is independently actionable and delay risks collapse. An exam caveat is that staying within scope does not excuse delaying urgent communication. A practical check is to state identifiers, signs, image finding, receiver, time, obtain read-back, document, and confirm rapid response continues.
