What action should be taken upon achieving ROSC?

Upon achieving Return of Spontaneous Circulation (ROSC), it is crucial to ensure that the patient receives supplemental oxygen. This action is vital because, after ROSC, the patient may still be in a compromised state, and providing supplemental oxygen helps to optimize tissue oxygenation, improve cellular function, and support the recovery of vital organs.

Maintaining adequate oxygen levels is essential for the prevention of hypoxia, which could lead to further complications or deterioration of the patient’s condition. Supplemental oxygen ensures that the body has enough oxygen to meet its metabolic demands, especially after the stress of cardiopulmonary resuscitation (CPR) and the accompanying lack of oxygen during cardiac arrest.

Other actions, such as defibrillation or administering medications, may be appropriate in different contexts but are not the immediate priorities once ROSC is achieved. Performing another round of CPR would not be indicated since the primary goal of CPR—restoring circulation—has been accomplished.
