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.
The compression ratio is the ratio of the volume of the cylinder and the combustion chamber when the piston is at the bottom, and the volume of the combustion chamber when the piston is at the top. Automotive engineers can improve fuel efficiency and fuel economy by designing engines with high compression ratios.The higher the ratio, the more compressed the air in the cylinder is.When the air is compressed, you get a more powerful explosion from the air-fuel mixture, and more of the fuel gets used.he higher the ratio, the more compressed the air in the cylinder is. When the air is compressed, you get a more powerful explosion from the air-fuel mixture, and more of the fuel gets used.
