Advanced Cardiovascular Life Support (ACLS) Practice Exam

What is the proper ventilation rate for a patient in cardiac arrest with an advanced airway in place?

1. 6-8 breaths per minute

2. 8-10 breaths per minute

3. 10-12 breaths per minute

4. 12-15 breaths per minute

The correct answer is: 8-10 breaths per minute

For a patient in cardiac arrest who has an advanced airway in place, the proper ventilation rate is 8-10 breaths per minute. This rate allows for adequate oxygenation while minimizing the risks of hyperventilation, which can lead to decreased venous return to the heart and impaired cardiac output. The rationale for this range is based on maintaining sufficient ventilation to support oxygenation without causing adverse effects. While rates above this range can lead to complications including increased intrathoracic pressure and potentially decreased effectiveness of chest compressions, the recommended ventilation rate strikes a balance between providing adequate ventilation and maintaining hemodynamic stability. Understanding this principle is crucial for effective management of a patient in cardiac arrest, as the focus remains on maximizing the quality of resuscitative efforts while adhering to established guidelines. For patients without an advanced airway, the recommended rate is different, reflecting the variations in airway management techniques and their physiological implications.
