Case Study........................................................................................................................................... 30. Synthesis of Instructional Design Research........................................................................................
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.
As of the 2010 ECC updates:    For ADULT CPR, the ratio is the same (30:2) for 1-person and  2-person CPR, but you should incorporate switching at least every 2  minutâ¦es/5 cycles  For CHILD/INFANT CPR, the ratio CHANGES from 30:2 (1-person) to  15:2 (2-person), along with the compressor adopting a modified hand  position in infant CPR.
