What can effective ventilation help to limit during resuscitation?

Effective ventilation during resuscitation plays a crucial role in preventing the buildup of carbon dioxide (CO2) in the bloodstream. When a person is experiencing cardiac arrest or other life-threatening conditions, their breathing often ceases or becomes insufficient, leading to a decrease in gas exchange. This causes CO2 to accumulate, which can lead to respiratory acidosis and further complications during resuscitation efforts.

By ensuring proper ventilation, rescuers can facilitate the removal of CO2, allowing for more stable acid-base balance in the body and enhancing the chances of a successful resuscitation. Additionally, the process supports oxygenation of the blood, but the specific limitation of CO2 buildup is the primary focus here. The other options, while related to critical care, do not directly relate to the immediate physiological benefits achieved through effective ventilation during the resuscitation process.
