•Cardiac compression allows the heart to maintain pump
functionby sequential filling and emptying of its
chambers with competant valves
maintaining the forward direction of flow.Palm
of one hand placed over lower sternum; heel of the other rests on dorsum of the lower hand.
•To get the
right speed and rhythm, count out loud as you do the compressions, saying "1 and 2 and 3 and 4
and 5!" Rest on each
"and," then compress on each number. Each series of 5 should take about 3 seconds. Force
sufficient to depress sternum by
3-5cms;relaxation is abrupt.
