ACCS Exam Q’s & A’s 100% Verified (Latest)
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...
- If given P/F ratio less than 200 good clue to increase PEEP
*Use fio2 instead of PEEP in hypotensive or hemodynamicly unstable patients*
Ventilation Issues - ACCS ✔✔For ACCS purposes, treating a pH up to as low 7.30
is reasonable
(particularly for ARDS where fixing a pH/PaCO2 may result in a lung injury)
Watch WOB - indicates asynchrony on vent or needs to be placed on one if not
on vent
Improving ventilation - conventional way ✔✔- Increase RR while ensuring
adequate I:E
- Cautiously consider increasing tidal volume but never beyond 8 ml/kg IBW
- Ensure patient is not air trapping
Improving ventilation - "advanced" ✔✔- Increase perfusion to health lung - bad
lung up, good
lung down (BLU GLD)
