Here are some technical specifications to keep in mind for CPR on the Adult when alone: 1  Attempt a 30 to 2 ratio. Thatâs 30 compressions, briefly pause and give 2 ventilations (breaths), then repeat until help arrives. 2  Try to maintain a rate of compressions at 100/min.  Try to keep interruptions of CPR to a minimum.
CPR for an Infant. If providing CPR for an infant the ratio of compressions to breaths remains the same but the method of performing compressions changes. For an infant you should use 2-3 fingers in the center of the chest on the lower half of the breast bone to compress the chest about 1 Â½â.
