    Out-of-hospital cardiac arrest (OHCA) increasingly affects older adults, who represent the majority of cases in developed countries.

  • 2

    Kishihara et al. assessed the impact of no-flow duration on neurological outcomes in older adults with witnessed cardiogenic OHCA.

  • 3

    The study found that the no-flow duration threshold for a favorable neurological outcome decreases with age, from 14 minutes for ages 65-74 to 0 minutes for those 95 and older.

  • 4

    The authors emphasize the need for caution in interpreting their findings due to variations in defining no-flow duration across studies.

  • 5

    Clinical application of the study's results should consider individual patient factors, as a 1% probability does not imply futility in resuscitation efforts.
