If the patient shows signs of return of spontaneous circulation, or ROSC, administer post-cardiac care. If a nonshockable rhythm is present and there is no pulse, continue with CPR.

What do you do after ROSC?

In summary, we recommend that comatose (ie, lack of meaningful response to verbal commands) adult patients with ROSC after out-of-hospital VF cardiac arrest should be cooled to 32°C to 34°C (89.6°F to 93.2°F) for 12 to 24 hours (Class I, LOE B).

Do you continue CPR with ROSC?

An increase of ETCO2 35-40 may indicate adequate tissue oxygenation and can be used to confirm return of spontaneous circulation (ROSC), however our experts recommend continuing CPR after the initial spike of ETCO2.
