A. activated clotting times less than 200 seconds
B. dynamic compliance of 0.8 ml/cm H2O or greater
C. oxygenation index of less than 40
D. PEEP of 10 cm H2O or less

Question 2

Answer to Question 1

ANS: B
A. Incorrect response: See explanation B.
B. Correct response: Measurement of dynamic compliance may be helpful in the assessment of recovery from ECLS. A dynamic compliance of 0.8 ml/cm H2O or greater has predicted successful discontinuation of ECLS. Successful weaning from ECLS has occurred at lower dynamic compliance values.
C. Incorrect response: See explanation B.
D. Incorrect response: See explanation B.

Answer to Question 2

ANS: D
A. Incorrect response: See explanation D.
B. Incorrect response: See explanation D.
C. Incorrect response: See explanation D.
D. Correct response: Seizures associated with fluid and electrolyte abnormalities can be seen at the time of cannulations, and during the early hours of ECLS. Pediatric patients (1 month to 18 years of age) who have a metabolic acidosis, a bicarbonate or inotrope/vasopressor requirement, CPR, or a left ventricular assist device before initiation of ECLS are at greater risk for the development of central nervous system complications.
