Desired V_T= 11ea68f7_d69d_ae11_b0a4_af5f3c6c0b45_TB1877_11 The desired target for V_T for this patient is 5 to 8 mL/kg IBW.Because the set V_T of 450 mL is at 5.9 mL/kg,there is room to increase the V_T.After calculating the desired V_T using the formula,the new volume is at 7.8 mL/kg.A V_T of 760 mL would be at 10 mL/kg IBW.
