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.
If alone, start high-quality cardiopulmonary resuscitation (CPR) at a compressions-to-breaths ratio of 30:2. If not alone, start high-quality CPR at a compressions-to-breaths ratio of 15:2. Every 2 minutes, check pulse, check rhythm, and switch compressors. In infants, start CPR if heart rate (HR) < 60 bpm and poor perfusion despite adequate oxygen and ventilation.
