Knowing when to stop the CPR Knowing the limits of your work location Knowing the complete details about the case 11. Why is chest recoil important1 Ribcage gets strengthened with recoil Chest recoil helps with oxygenation Increased chest pressures impair blood flow returning to the heart Heart can get injured if there's no recoil 12.

One secures the mask, the other squueezes the bag. 24. When performing CPR with an advanced airway,1 Maintain 30:2 compressions to breaths ratio Compressions are continuous and breaths at every 6 seconds Advanced airway should be attempted only if there's a pulse No need of giving breaths, just continue compressions 25. What happens with interruptions in chest compressions?1 Rescuers get tired Perfusion pressures go down Improved output from heart Drastic improvement in perfusion 26. Which is not a feature of high quality CPR1 Depth of 1/3rd chest diameter (2inches/5cms) Minimize interruptions Minimize chest recoil A rate of 100-120 compressions/min 27. Regarding depth of chest compressions1 Compress upto 4cm in adults Compress 5cm depth Compress as deep as possible Compress 1/3rd the chest 28. What to do after delivering a shock?1 Check pulse for 10seconds Remove pads from chest Wait for 2 minutes Resume CPR for 2 minutes Turn off the AED. and do CPR 29.
