What are the current recommendations to decrease CO production that was recommended by APSF?
1) Turn off gas flows when the anesthesia machine is not in use.
2)Change absorbents regularly especially on Monday mornings. Since the absorbent may become desiccated over the weeekend.
3) Change absorbent whenever the color change indicates exhaustion.
