l D. corticosteroids
l



l (Ans- B. heliox therapy l l l



Heliox therapy is most appropriate. Helium, when combined with oxygen, isless
l l l l l l l l l l l l



viscous than pure oxygen or room air, which is made up mostly of nitrogen. This a
l l l l l l l l l l l l l l l



llows patients to breathe in gases with less airway resistance.

What would occur on a time-

ed?


l A. increase in tidal volume
l l l l



l B. decrease in inspiratory time
l l l l



l C. decrease in tidal volume
l l l l



l D. increase in inspiratory time
l l l l



l (Ans- A. increased in tidal volume
l l l l l



On a time- l l



cycled ventilator inspiratory time is predetermined. So, if the flowrate is increase

d while the mandatory rate is unchanged, the result would be an increase in tidal

volume.
