broken ribs during CPR is quite common, especially among older people where their bone more fragile.
but better broken ribs than dead.

FYI, there r law that protects CPR giver that even cause injury, cant sue the CPR giver.
but, u no CPR certificate, & doing it wrong like the video, they van argued that u're causing harm more than helping, hence can sue u.

source: i'm CPR certified. need to renew every 3 years.

u can absolutely sue.
ie like shown in the video.
if u dunno what u're doing, dun hog the spotlight & be a hero.
help go look for people who knows CPR better.

better than administer poor cpr and deny the victim of having proper cpr
if you don't know how to do proper cpr, then better find someone who know even if it takes 5 minutes
a delayed proper cpr within 5 minutes is better than an immediate bad cpr that prolonged for 30 minutes
first do no harm. so if know nothing, do nothing

Thanks for the tip bro, I will do that if it is you lying there. 
oh maybe even better i help you call 999
