Randomized Controlled Trial
Teaching recognition of agonal breathing improves accuracy of diagnosing cardiac arrest.
Agonal breathing is present in up to 40% of pre-hospital cardiac arrests and is commonly mistaken as a sign of circulation leading to omission of bystander resuscitation. The aim of this study was to test the hypothesis that specific tuition on agonal breathing improves the accuracy of checking for signs of circulation as a diagnostic test for cardiac arrest. ⋯ This study demonstrates improved diagnostic accuracy and sensitivity of "checking for signs of circulation" by teaching CPR providers to recognise agonal breathing as a sign of cardiac arrest.
