The CPR compression ratio for infants and children is 30 compressions to 2 breaths. 2 people CPR compression ratio for infants is 15 compressions to 2 breaths. 2 people CPR coâ¦mpression ratio for children is 30 compressions to 2 breaths.
Engines with higher compression ratios are generally considered better because they create more power while still maintaining efficiency. Ad. To calculate the compression ratio of an engine, an engineer would first calculate the volume a cylinder in the engine can hold when the piston is at the bottom of the cylinder.During one stroke of the engine, the piston moves from the bottom up toward the top and compresses the air-fuel mixture.0 hilariously insightful foreign words. Compression ratio refers to the volume, or amount, of an air and fuel mixture that the combustion chamber in a combustion engine can hold when it is empty and at its largest size compared to the volume it holds when the mixture is compressed down to the smallest size possible.
