SPW - great post
I would only take issue with you about Pulmonary Embolus, clot which moves from the legs(usually) through the heart and lodges in the lung vessels, blocking the blood flow. Chest compressions can break up the clot and distribute it to the smaller vessels, allowing more blood to flow through the lungs and pick up oxygen. No disrepect intended on paramedic CPR - they are still better than most, and the good are very good. I've had the honour to fly missions with some of the best.

latest changes are
1. When obtaining help, ask for an automated external defibrillator (AED), if one is available.
2. Compress the chest to a depth of 5-6 cm and at a rate of 100-120 min-1.
3. Give each rescue breath over 1 s rather than 2 s.
4. Do not stop to check the victim or discontinue CPR unless the victim starts to
show signs of regaining consciousness, such as coughing, opening his eyes, speaking, or moving purposefully AND starts to breathe normally.
5. Teach CPR to laypeople with an emphasis on chest compression, but include ventilation as the standard, particularly for those with a duty of care.
In addition, advice has been added on the use of oxygen, and how to manage a victim who regurgitates stomach contents during resuscitation.
