You and your partner are the responding medical crew on a RW aircraft. You are dispatched to rendevous with a ground unit for a 74-inch tall, 98kg, 66 YOA M. Upon arrival, the ground crew is preparing for RSI due to hypoxic and hypercarbic respiratory failure. Current VS are as follows: HR: 144, BP: 68/44, Spo2: 88%, RR: 56, EtCO2: 14. Intubation is performed with no adverse events and VS are being tended to accordingly. The ground paramedic reads their current vent settings to be:
Vt - 410cc
RR - 14
FiO2 - 1.0
PEEP - 5
I:E - 1:2
Please describe what values, if any, you would like to change and why
**Answer may be approximated as long as still within the presenter's set limits**
Vt - 475
RR - 22
FiO2 - 1.0
PEEP - 8
I:E - 1:2.5
