30/2
Compress the chest about 1 1/2 inches per compression.
Child 2 rescuer CPR is cycles of 15 compressions to 2 breaths.

A combination of breaths and chest compression cycles.
Absorption & vapor compression.
When two rescuers are preforming CPR on a child, the compression to breath ratio is 15:2. That is 15 compressions 1-1.5" deep at a rate of 100 compressions a min. Each rescue breath should last about one second and make the chest clearly rise. The cycle is then repeated, fifteen compressions and two breaths. The rescuers should change positions about every 2min or about 10 cycles.
Well we breath in oxygen, and release co2, which plants breath in then release oxygen. thus they are almost the same cycles
Two strokes have two cycles the piston go through intake/compression and ignition/exhaust where four strokes have four separate piston cycles intake compression ignition and exhaust.
Sound is a compression or rarefication of air. That compression is measured in frequency (Hertz) or cycles per sec . 440 Hertz is A or "Concert Pitch"
For two rescuer infant CPR; one rescuer should give the breaths, the other rescuer performs compressions using the 2 thumbs encircling hands technique. Give cycles of 15 compressions and 2 breaths.
