how do u find out the I:E ratio an insp. flow demand?
(you are provided with the RR, Vt, and IT(insp time)
1. 60 sec divided by the RR
2. then subtract the IT from that number. that will give you the ET
3. then add insp and exp ratio together
4. mutiply that # with the RR and multiply that by the Vt. convert answer into liters
5. that will give you the insp flow demand.
