As a medical professional with expertise in emergency care, I can explain the effects of excessive ventilation during CPR.
During CPR, the primary goal is to provide adequate oxygenation and circulation to the patient. Excessive ventilation, which means giving too many breaths or too much volume per breath, can have several negative effects:
1. Stomach Distention: Over-inflation of the lungs can push air into the stomach, leading to distention. This can make it difficult for the patient to breathe and can also lead to vomiting, which can further obstruct the airway.
2. Reduced Chest Compressions: Focusing too much on ventilation can reduce the number and quality of chest compressions, which are crucial for maintaining blood flow to the brain and heart.
3. Impaired Cardiac Output: Excessive ventilation can interfere with the mechanics of the heart's pumping action, leading to reduced cardiac output and less effective circulation of blood and oxygen.
4. Increased Intrathoracic Pressure: Over-ventilation can increase the pressure inside the chest cavity, which can impede blood flow back to the heart, especially from the veins below the level of the heart.
5. Hypoventilation: Ironically, excessive ventilation can also lead to inadequate ventilation if it disrupts the normal breathing pattern and the rescuer does not allow enough time for the patient to exhale.
6. Barotrauma: High pressure from forced ventilation can cause lung damage, known as barotrauma, which can lead to conditions like pneumothorax (collapsed lung).
7.
Ineffective CPR: Ultimately, excessive ventilation can lead to ineffective CPR, reducing the chances of successful resuscitation.
It's important to follow the current guidelines for CPR, which emphasize chest compressions over ventilation, with a ratio of 30 compressions to 2 breaths for adults in most situations.

Excessive ventilation during cardiopulmonary resuscitation (CPR) is likely to increase intrathoracic pressure and decrease coronary perfusion pressure, according to a new study. ... To further investigate, his group observed EMS personnel as they performed CPR on 13 patients in cardiac arrest, none of whom survived.
