ACCS Review Exam with Accurate
Answers
IBW calculation in Adults - ✔✔-Male = 50+2.5(ht in inches - 60)
-Female = 45.5+2.5(ht in inches - 60)
Tidal Volume (TV) - ✔✔Always start at 8ml/kg of IBW (can be range of 6-10 on test)
Pressure - ✔✔18-22 cm H2O - target appropriate tidal volume of 6-10 ml/kg of IBW
Respiratory Rate (initial vent settings) - ✔✔- 10-24 considered normal on exam
- Can be as low as 8
- Pick higher range for ARDS
- Watch I:E ratios for air trapping
I time and I:E ratios - ✔✔- Normal I times 0.8-1.2
- Normal I:E 1:2 - 1:3
- Larger I:E times for COPD,Asthma,CF 1:4-1:5
PEEP - ✔✔- For exam anything over 6 is therapeutic and a reason needs to exist before applying
it
- Uses of higher PEEP - refractory hypoxia ( V/Q mismatch )
- If given P/F ratio less than 200 good clue to increase PEEP
*Use fio2 instead of PEEP in hypotensive or hemodynamicly unstable patients*
