The recommended standard CPR cycle ratio is $30$ chest compressions to $2$ rescue breaths. If a trained first-aider performs $5$ complete cycles, how many chest compressions are given in total?
$100$
$120$
$150$
$160$
Solution
Total compressions $= 30 \text{ compressions per cycle} \times 5 \text{ cycles} = 150\text{ compressions}$.
