The ratio of compressions to ventilations in adult cpr is 20 to 4. 30 to 2. 15 to 1. 5 to 1.

CPR or Cardiopulmonary Resuscitation is a technique used in emergency cases for people who become suddenly unconscious without the presence of pulse and respiration upon assessment. The ratio of compressions to ventilations in adult CPR is 30:2. Compressions per minute should be 100-120 compressions. 

I’ve personally felt invisible all my life, especially when a friend turned out to be fake and didn’t seem to take any type of interest in what i said or any type of input i said. being invisible is a terrifying feeling to experience due to the fact you feel like no one sees you and just sees you (sorry if that doesn’t make sense). it’s like a deep emptiness that no one can fill, just you; you have to fix that emptiness by yourself and you don’t really want , or in some cases want to be invisible. i can see many invisible people when they intentionally stay away from people that can potentially hurt them in any way. also, when a person intentionally breaks off a connection so they aren’t seen by people.hope it

It is for u to answer
