A male patient (74-kg IBW)is being ventilated with PC-CMV,f = 12/min,PIP = 20 cm H₂O,T_I = 1.5 seconds;the resulting flow-time scalar is shown below.The patient's measured V_T is 435 mL.ABG results on these settings are: pH 7.32,PaCO₂ 54 mm Hg,HCO₃^- 25 mEq/L.The most appropriate action to take is which of the following?

The flow-time scalar shows that T_Iis adequate,because it shows a time of zero flow during inspiration.Therefore,changing T_I would not be appropriate.The measured V_T for this patient is at 5.9 mL/kg IBW;therefore,the V_T could be increased.In the PC mode,this would be done with by increasing the set PIP using the following formulas: Desired V_T = 11ea68f7_d69d_fc34_b0a4_938c8296a817_TB1877_11 = approximately 590 mL Desired P = 11ea68f7_d69d_fc35_b0a4_090eca0240b5_TB1877_11 = 26.8 cm H₂O
