What is an effect of excessive ventilation ACLS Test?

Avoid excessive ventilation, which may reduce cerebral blood flow due to the decrease in the PaCO2 level. Excessive ventilation also has the potential to cause high intrathoracic pressures, leading to adverse hemodynamic effects (decreased cardiac output and cerebral perfusion) during the post arrest phase.

What is an effect of excessive ventilation decreased cardiac output?

What happens with excessive breathing is that it increases intrathoracic pressure, which reduces coronary perfusion because blood can't flow back into the heart. “It reduces venous blood return to the heart, and reduced blood return means reduced blood outflow from the heart,” says Aufderheide. Jun 30, 2004

What is a complication of excessive ventilation?

Excessive ventilation can also cause splinting of the patient's diaphragm, which can make it much more difficult to continue ventilation and also impede the output of the heart.

Why do you need to allow for a complete recoil after each compression?

Full recoil is required so the blood can re-fill the heart's chambers between compressions. Therefore, full recoil is essential because, as the chest is elevated, the negative pressure that is exerted actually causes the blood to be drawn back into the heart.

Why should you avoid excessive ventilation?

❖ Excessive ventilation may potentially lead to adverse hemodynamic effects when intrathoracic pressures are increased and because of potential decreases in cerebral blood flow when PACO2 decreases.
