A 5'10" male patient with normal lungs has been intubated and requires mechanical ventilation with volume-controlled continuous mandatory ventilation (VC-CMV).The tidal volume and ventilator rate settings that should be recommended for this patient are which of the following?

First calculate ideal body weight (IBW)for a male,which is 106 + 6(ht - 60)= 75 kg.Then using the range of 5-7 mL/kg IBW,the tidal volume range for this patient is 375⁻⁵25 mL.Minute ventilation is about 100 mL/kg IBW.Therefore,minute ventilation should be approximately 7.5 L/min.Dividing the calculated minute ventilation by the tidal volume range for this patient provides a range of rates for the tidal volumes: 14-20 breaths/min depending on the set volumes.The most appropriate volume and rate combination for this patient is 525 mL × 14 breaths/min = 7.35 L/min.
