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.
During compressions on a child patient, depress the chest about 2 inches. In the adult procedure, rescuers should depress the chest at least 2 inches. If two rescuers are performing CPR, the ratio of compressions to rescue breaths is 15:2. The ratio for lone rescuers and all adult procedures is 30:2. A manual defibrillator is preferred for infant patients, although an automatic defibrillator may be used if a manual defibrillator is not available.
