The most appropriate tidal volume setting for a 6'3 male ventilator patient with normal lungs is which of the following?
 
  a. 300 mL
  b. 500 mL
  c. 700 mL
  d. 900 mL

Question 2

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?
  a. VT = 525 mL, rate = 14 breaths/min
  b. VT = 750 mL, rate = 12 breaths/min
  c. VT = 825 mL, rate = 10 breaths/min
  d. VT = 950 mL, rate = 8 breaths/min

Answer to Question 1

ANS: B
First calculate ideal body weight (IBW) = 106 + 6(ht  60). Then using the range of 5-7 mL/kg IBW the tidal volume range for this patient is 445-623 mL.

Answer to Question 2

ANS: A
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 ven-tilation 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 pro-vides 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.
