    End-tidal carbon dioxide (EtCO2) is widely used for confirming airway placement during in-hospital cardiac arrest, with 92.6% adherence from 2019 to 2023.

  • 2

    For monitoring cardiopulmonary resuscitation (CPR), only 35.3% of in-hospital cardiac arrests utilized EtCO2 from 2019 to 2023.

  • 3

    There is minimal variation in hospital use of EtCO2 for airway confirmation, with a median adherence rate of 94.0%.

  • 4

    Significant variability exists among hospitals regarding the use of EtCO2 for monitoring CPR quality during cardiac arrest.

  • 5

    Despite widespread use for airway confirmation, adherence to guidelines for CPR monitoring with EtCO2 shows notable gaps.
