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.
In respiratory physiology, the ventilation/perfusion ratio (or V/Q ratio) is a measurement used to assess the efficiency and adequacy of the matching of two variables:  1 V â ventilation â the air that reaches the alveoli. 2 Q â perfusion â the blood that reaches the alveoli.herefore, under these conditions, the ideal ventilation perfusion ratio would be about 0.95. If one were to consider humidified air (with less oxygen), then the ideal v/q ratio would be in the vicinity of 1.0, thus leading to concept of ventilation-perfusion equality or ventilation-perfusion matching.
