Use of the Drger E-4 nebulizer in the Neo setting will do which of the following?
 
  a. Increase the base flow from 6 L/min to 11 L/min
  b. Cause a 6 decrease in the oxygen con-centration in any mode
  c. Divert 6 L/min away from the patient cir-cuit to the nebulizer
  d. Decrease oxygen concentration signifi-cantly with rates greater than 12 breaths/min

Question 2

Which of the following statements concerning the use of AutoFlow for neonates on the Drger E-4 is true?
 
  a. AutoFlow is an adult mode and should not be used with neonates.
  b. The ventilator's internal flow sensor is al-ways used with neonates on AutoFlow.
  c. Two test breaths determine the appropriate pressure to deliver volume in AutoFlow.
  d. In AutoFlow, the highest pressure to de-liver the volume is the high-pressure limit setting.

Answer to Question 1

ANS: D
Use of the Drger E-4 nebulizer in the Neo setting increases the base flow from 6 L/min to 9 L/min. Delivered oxygen concentrations decrease slightly from the level set. The amount of de-crease is less than 4 at breath rates greater than 12 per minute. When operating at mandatory breath rates of less than 12 per minute, the nebulizer should not be used because of the potential-ly significant drop in oxygen concentration.

Answer to Question 2

ANS: C
When the flow sensor is attached during AutoFlow in neonates, the unit provides two test breaths, first with a pressure of 5 cm H2O and then with a pressure equal to 75 of that required to deliver the set volume.

A serious new warning has been established for pregnant women against taking ACE inhibitors during pregnancy. In the study, the risk of major birth defects in children whose mothers took ACE inhibitors during the first trimester was nearly three times higher than in children whose mothers didn't take ACE inhibitors. Physicians can prescribe alternative medications for pregnant women who have symptoms of high blood pressure.
