What problem is associated with using pressure-volume loops to determine potential levels of appropriate PEEP for protective lung strategy?
A. Patients need to be sedated and paralyzed.
B. Technology is unavailable to accommodate the widespread use of this strategy.
C. This protective lung strategy cannot be used in all patients receiving mechanical ventilation.
D. This strategy only works for patients who have decreased pulmonary compliance.
?ANS: A
A. Correct response: Obtaining static pressure-volume curves to determine potential levels of appropriate PEEP requires that the patients be sedated and paralyzed, and that these measurements be performed repeatedly. Therefore, the use of pressure-volume loops to limit VILI has not entered routine clinical practice.
B. Incorrect response: See explanation A.
C. Incorrect response: See explanation A.
D. Incorrect response: See explanation A.
