Even though the two medics plus two emergency medical technicians who worked on Rivers restarted her heart and got oxygen into her lungs using the tracheal tube and bag-valve mask
, Rivers' brain has already been deprived of oxygen for far too long.
Two experiments were performed to compare the Threshold IMT device-in-reverse pressure to that of the actual pressure measured via a pressure monitor (PF-300; IMT-medical, Switzerland) under two separate conditions, including (1) manually generated expiratory flow using a bag-valve mask
and, (2) human subject generated expiratory flow.
In addition, significant improvements were seen in both performing and teaching peripheral intravenous techniques, central line placement, inserting an intraosseous needle, bag-valve mask
ventilation, endotracheal intubation, and chest needle decompression.
I make certain I have a bag-valve mask
resuscitation bag and suction with extra tubing available, and I ensure the suction is working.
A bag-valve mask
system is used to perform this procedure.
