saw

saw someone comment why she was giving cpr to someone with a head injury but the boy had stopped breathing and she found no heartbeat, the first thing you do as a medical professional is cpr in that situation, a human can survive only about 4? minutes without oxygen getting to the brain whether or not its a head injury without oxygen they would not come back. There have been some cases of people surviving without oxygen longer but as a general rule of thumb its about 4 minutes plus she was timing the situation beforehand. In the time era shes in *which i assume its likely Victorian* not much can be done about a serious head injury besides hoping it heals, with the little equipment *none* she had she did the absolute best possible means of getting the boy to come back to life cause he was DEAD no pulse and breathing.
