What should be avoided to ensure effective CPR?

To ensure effective CPR, it is important to avoid excessive ventilations. When performing CPR, maintaining an appropriate ratio of chest compressions to breaths is crucial. The recommended ratio for adults is typically 30 compressions followed by 2 breaths. If a rescuer provides too many breaths, it can lead to interruptions in chest compressions, resulting in reduced blood flow to vital organs. Excessive ventilations can also increase intrathoracic pressure, which may inhibit blood return to the heart and decrease the effectiveness of the compressions.

By focusing on high-quality compressions, minimizing interruptions, and achieving the correct compression depth, the rescuer maintains optimal blood circulation and oxygen delivery to the body, which are critical during a cardiac arrest situation. Balancing compressions and ventilations is key to effective CPR, making it essential to avoid excessive ventilations to maximize the chance of survival for the patient.
