1.
Position of your hands during Chest compressions

Place them close to the neck
At 90 degrees to the floor, with straight elbows
At 90 degrees to the floor, with elbows bent to 90 degrees
Place them at the center of abdomen
2.
Which is not a feature of high quality CPR
1
A rate of 100-120 compressions/min
Minimize chest recoil
Minimize interruptions
Depth of 1/3rd chest diameter (2inches/5cms)

1
Use one hand to compress at tip of sternum
Place 2 fingers on lower half of sternum at nipple level
Use 2 hands as in adults in center of the chest
Place fingers at tip of the sternum
5.
What happens with interruptions in chest compressions?
1
Drastic improvement in perfusion
Rescuers get tired
Improved output from heart
Perfusion pressures go down
6.
What happens when you compress at a faster rate than recommended 100-120 / min?
1
You might break the ribcage
Oxygen cannot reach lungs
Heart chambers will not have time to refill
You will get tired faster
7.
Why is chest recoil important
1
Ribcage gets strengthened with recoil
Heart can get injured if there’s no recoil
Increased chest pressures impair blood flow returning to the heart
Chest recoil helps with oxygenation
