Question 1

Assessing passive leg raise for fluid responsiveness using ETCO2?

Answer 1

increasing venous return with PLR boosts returning Co2, and this will be reflected by ETCO2.

• if . ETCO@ rises by 5% a fluid bolus should augment CO by 15%
• effect of of PLR is 1-3 minutes after maneuver performed

Question 2

Answer 2

passive patient, TV 8cc/kg, no cor pulmonale or elevated intraabdominal pressure
