Final answer:
The ventilation device should be connected to a Douglas bag method before an anticipated resuscitation. The Douglas bag method collects expired air and allows you to provide oxygen in any concentration.
Step-by-step explanation:
Before an anticipated resuscitation, the ventilation device should be connected to a Douglas bag method. The Douglas bag method is a canvas or plastic bag with a variable capacity that collects the expired air. By collecting the expired air, the bag enables you to measure the rates of oxygen utilization and carbon dioxide production. It allows you to provide oxygen in any concentration from room air up to 100% oxygen.
