A patient's baseline arterial blood gas (ABG) reveals a partial pressure of oxygen (PaO2) of 78 mm Hg while receiving 35 supplemental oxygen.
 
  What should the ventilator fractional inspired oxygen (FIO2) be set at to obtain a target PaO2 of 95 mm Hg?
  a. 0.34
  b. 0.43
  c. 0.55
  d. 0.67

Question 2

The mode of ventilation that provides pressure-limited, time-cycled breaths that use a set tidal volume as a feedback control is which of the following?
 
  a. Pressure support ventilation (PSV)
  b. Pressure-regulated volume control (PRVC)
  c. Pressure-controlled continuous mandatory ventilation (PC-CMV)
  d. Bilevel positive airway pressure (Bilevel PAP)

Answer to Question 1

ANS: B

Answer to Question 2

ANS: B
Pressure support ventilation (PSV) is pressure-limited and flow-cycled. Pressure regulated vol-ume control (PRVC) is a dual control mode of ventilation that provides the benefits of pressure breathing along with targeting a set volume. These breaths are pressure-limited, time-cycled, and use tidal volume as a feedback. The pressure is adjusted by the ventilator to meet the set volume. Pressure-controlled continuous mandatory ventilation (PC-CMV) is pressure-limited and time-cycled but does not have a volume feedback system. Bilevel PAP is similar to PC-CMV in that it is pressure-limited and time-cycled with no volume feedback.

Did you know?

Nearly 31 million adults in America have a total cholesterol level that is more than 240 mg per dL.

Did you know?

The heart is located in the center of the chest, with part of it tipped slightly so that it taps against the left side of the chest.

Did you know?

Patients who cannot swallow may receive nutrition via a parenteral route—usually, a catheter is inserted through the chest into a large vein going into the heart.

Did you know?

Astigmatism is the most common vision problem. It may accompany nearsightedness or farsightedness. It is usually caused by an irregularly shaped cornea, but sometimes it is the result of an irregularly shaped lens. Either type can be corrected by eyeglasses, contact lenses, or refractive surgery.

Did you know?

As many as 28% of hospitalized patients requiring mechanical ventilators to help them breathe (for more than 48 hours) will develop ventilator-associated pneumonia. Current therapy involves intravenous antibiotics, but new antibiotics that can be inhaled (and more directly treat the infection) are being developed.
