What does AED stand for?

15:2
You should check for a pulse for up to 30 seconds before starting compressions.
check for no more than 10 seconds but more than 5
What is the correct compression rate per minute?
100–120 compressions/min.
What is the correct ventilation rate for adults with an advanced airway in place?
breath every 6 seconds (10 breaths/min) with continuous compressions. AKA - rescue breaths
What should you do immediately after delivering a shock with an AED?
Resume chest compressions.
What should you do if someone is choking but still able to cough or talk?
Encourage them to keep coughing
True or False: CPR alone can restart a heart.
False – CPR keeps blood circulating until defibrillation/advanced care.
What is the correct hand placement for adult compressions?

15:2 compressions-to-breaths.
Where should AED pads be placed on an adult?
Right upper chest, left lower chest (below armpit)
How do you check responsiveness in an infant?
Tap the soles of the feet and shout.
What is the most common mistake in CPR compressions?
Not pressing deep enough or not allowing full chest recoil.
What is the ratio of compressions to breaths for single rescuer adult CPR?
30:2
What is the recommended volume for each rescue breath?
Just enough to see the chest rise.
Can you use adult AED pads on a child if pediatric pads are not available?
Yes, but ensure pads don’t touch each other.
What is the compression depth for infants?
4 cm/ 1.5 inches
Should you remove an implanted pacemaker before placing AED pads?
No – place pads at least 1 inch away from the device.
Compression ratio for infant CPR (single rescuer)
30:2
What device can provide supplemental oxygen during BLS when available?
Bag-valve-mask (BVM) with oxygen.
What do you do while the AED is charging?
Continue giving last couple compressions.
In a drowning victim, what should you do first before compressions?
Provide 2 rescue breaths.
