Question

Bystanders have pulled a young woman with a pulse but no respirations out of a lake. One of them is administering rescue breaths at a rate of one every 5-6 seconds while waiting for EMS to arrive. Which of the following is true about rescue breaths?

A. Each breath should result in visible chest rise.
B. Give each breath over 1 second.
C. The pulse should be checked every 2 minutes.
D. All of the above.

Answer 1

The correct answer is D. All of the above, which includes ensuring visible chest rise with each breath given over 1 second and checking the pulse every 2 minutes during rescue breaths as part of CPR.

Step-by-step explanation:

The correct option : d

When administering rescue breaths, it's essential that each breath should result in visible chest rise, which confirms that air is entering the lungs. Each breath should be given over approximately 1 second to ensure adequate ventilation without overinflation, which could damage the lungs. Additionally, the rescuer needs to check the pulse every 2 minutes to ensure that the victim still has adequate circulation, and if not, to commence CPR with chest compressions. Proper technique is crucial as incorrect application of CPR can cause additional injuries, such as broken ribs or damage to internal organs.

Rescue breaths tend to be given less frequently than in the past, with current emphasis on high-quality chest compressions, particularly when the rescuer is alone without help or a barrier device. Rescue breaths are a component of CPR, which is vital in maintaining adequate oxygenation to the brain and other vital organs after cardiac or respiratory arrest. This is especially crucial as irreversible brain damage can occur within minutes without oxygen. Although rescue techniques should be performed by individuals trained in CPR, untrained bystanders can still perform chest compressions until medical professionals arrive.
