There is an artificial syringe that is inserted into the left armpit of the dead patient, to pretend the dead body alive, and breathing!
If you have any patients in ICU, and if he/she dies, then check the body from the hospital. Check if there is any small hole in the left side of the corpse. If there is a hole, if you find any then make sure to get help from the administration.
Many hospitals are doing this for making money. One serious patient takes a lot of money to keep one day at ICU, and with this artificial injection, it is very easy to keep a dead patient breathing for 28 to 32 days.
