If an advanced airway is in place during CPR, what is the correct ventilation delivery rate?

1 ventilation every 2 to 3 seconds
1 ventilation every 30 seconds
1 ventilation every minute
1 ventilation every 5 seconds

The correct answer is: 1 ventilation every 2 to 3 seconds

When an advanced airway is in place during CPR, the correct ventilation delivery rate is to administer 1 ventilation every 2 to 3 seconds. This means that rescuers should provide approximately 10 to 12 breaths per minute. This rate is based on the understanding that an advanced airway, such as an endotracheal tube, allows for more effective ventilation than traditional mouth-to-mouth or bag-mask techniques. It ensures that while one rescuer is performing chest compressions, another can deliver ventilations without interrupting the high-quality compressions that are crucial for maintaining circulation and perfusion. The other options suggest ventilation rates that are either too infrequent or too quick, which may not provide adequate oxygenation or maintain the compression rhythm necessary for effective CPR. Using the correct ventilation rate with an advanced airway is vital for the successful resuscitation of a patient in cardiac arrest.
