The recommended compression rate is at least 100 compressions per
minute.
Be sure to achieve the full compression depth of at least 5cm
(2 inches) for adult patients.
For children, be sure to achieve the full compression depth, which
should be at least 1/3 of chest anteroposterior diameter of
approximately 4cm (1.5inch) for infants and approx. 5cm (2inch) for the
child.
Achieve enough compression speed and depth, allow the chest to
recoil completely after each compression, minimize interruptions in
chest compression, and refrain from excessive artificial respiration.
Perform the chest compression before one-man rescuer tries artificial
respiration. (Perform in order of chest compression 30 times, then
followed by artificial respiration 2 times.)
