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.
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.
