Select the Question that corresponds to the displayed Answer.
incorrect
11. >PaO2 of less than 10 after increasing FIO2 by 20%, inadequate arterial oxygenation w/acceptable FIO2, PaO2 <60 (SaO2 <90) w/FIO2 >40-50%, P/F <300 ALI, P/F <200 ARDS.




incorrect
12. VT 6-8, RR 12-15 (can go to 30), Flow set to Itime, ITime target is 1.2 seconds, mode VC-CMV, PEEP 5-8, FIO2 100%




incorrect
13. inability of heart and lungs to provide adequate tissue oxygenation or removal of CO2




incorrect
14. BIG 4-APNEA, ACUTE VENT FAILURE (>CO2 W/PH <7.2), IMPENDING VENT FAILURE (RR >35 AND “CLINICAL PRESENTATION), SEVERE O2 PROBLEM (SHUNT, DIFFUSION DEFECT)




incorrect
15. increased Paw that can lead to cardio effects, shortens Etime, long ITime can cause airtrapping




incorrect
16. mode, VT, RR, I:E ratio, Flow, VE, PEEP, Trigger/Sensitivity, FIO2, Alarms




incorrect
17. same as normal, but may adjust after 24 hours for increased ICP, hyperventilation to target CO2 of 25-30 to reduce ICP (<CO2 will cause vasoconstriction and <blood volume therefore reducing ICP




incorrect
18. assess leak size by measuring inspired versus expired VT, BFV need chest tube, VC not working change to high frequency, also keep PEEP to minimum or 0, and small VT 4-8, may need surgical repair.




incorrect
19. 1-support and manipulate gas exchange (alv vent CO2 & PH), 2-increase lung volume (end inspiratory-end expiratory inflation and FRC), 3-reduce or manipulate WOB, 4-minimize cardiovascular involvement




incorrect
20. MIP >-20cmH20 (norm -80-100), VC <10mL/kg (norm 65-75), MVV <2xVE (norm 120-180L/min)
