The therapist desires to mechanically ventilate a patient with a mode that provides an increased I:E ratio, encourages spontaneous breathing, and lowers pressure fluctuations as tidal volume is delivered. Which of the following modes would be appropriate?
A. pressure-regulated volume control ventilation
B. inverse ratio ventilation
C. airway pressure release ventilation
D. synchronized intermittent mandatory ventilation
?ANS: C
A. Incorrect response: See explanation C.
B. Incorrect response: See explanation C.
C. Correct response: Airway pressure release ventilation (APRV) involves the use of long I:E ratios, less variation from in the delivered VT from breath to breath, and a spontaneously breathing patient. In addition to the recruitment effects cause by the long I:E ratios, the required spontaneously breathing has been shown to better distribute ventilation to dependent lung regions, thereby improving ventilation-perfusion relationships.
D. Incorrect response: See Explanation C.
