During pressure-targeted ventilation with volume guaranteed for every breath, the set volume is not met. Which of the following phase variables would cycle that breath?
 
  a. Time c. Volume
  b. Flow d. Pressure

Question 2

What is the expiratory time when the tidal volume is 700 mL, the flow rate is 50 L/min, and the inspiratory time-to-expiratory time ratio is 1:3?
 
  a. 0.42 second c. 2.52 seconds
  b. 0.70 second d. 4.67 seconds

Answer to Question 1

ANS: C
If the volume is not delivered by the time flow decreases to its set value during pressure-targeted ventilation with volume guaranteed for every breath, the flow continues at the amount set on the flow control until the set tidal volume is delivered. Inspiration becomes volume cycled.

Answer to Question 2

ANS: C
Inspiratory time = Tidal volume (in liters)  Flow rate (in liters/second) = 0.7 L  0.83 L/s = 0.84 s. Expiratory time = 3  Inspiratory time = 3  0.84 = 2.52 s.

A cataract is a clouding of the eyes' natural lens. As we age, some clouding of the lens may occur. The first sign of a cataract is usually blurry vision. Although glasses and other visual aids may at first help a person with cataracts, surgery may become inevitable. Cataract surgery is very successful in restoring vision, and it is the most frequently performed surgery in the United States.
