Hi I'm an Australian adult ICU nurse who is now in in a PICU in the New Orleans. There is no way ozzie nurses can double up.Firstly,here you don't touch the vents.I can only touch the Fio2.I don't even give nebulizer treatments(i can but tha'ts resp therapists job).When patients are admitted from OT/Er and they require a ventilator the resp tehrapist sets everything up and attaches patient.We are allowed to suction but we don't tie ETT tapes,do trachy care. Secondly,when you need you drips you scan an order down to phramacy and they draw it all up for you and send it up. Everything is computerized and there'sfar much more virtual paperwork. There obviously are pro and cons to both systems but you are expected to do alot more Oz. Hope that sheds some light,the two systems are completely different
