1. Position of your hands during Chest compressions
1
At 90 degrees to the floor, with straight elbows
Place them close to the neck
At 90 degrees to the floor, with elbows bent to 90 degrees
Place them at the center of abdomen

Place fingers at tip of the sternum
Place 2 fingers on lower half of sternum at nipple level
Use one hand to compress at tip of sternum
4. What happens with interruptions in chest compressions?
1
Improved output from heart
Drastic improvement in perfusion
Perfusion pressures go down
Rescuers get tired
5. What happens when you compress at a faster rate than recommended 100-120 / min?
1
You will get tired faster
You might break the ribcage
Heart chambers will not have time to refill

Flat and firm
Surface with a bump in middle

Ribcage gets strengthened with recoil
Chest recoil helps with oxygenation
