Randomized Controlled Trial
Evaluation of isoflurane and sevoflurane vaporizers over a wide range of oxygen flow rates.
To examine the accuracy and precision of isoflurane and sevoflurane anesthetic vaporizers. ⋯ A possible explanation for the inaccuracy of the isoflurane vaporizer may be that it was manufactured to be accurate with air but not oxygen, which must be accounted for when using the vaporizer with oxygen, especially with nonrebreathing systems. The sevoflurane vaporizer may not deliver accurate agent concentrations at high flow and high dial settings. Both vaporizers are suitable for clinical use with a wide range of oxygen flow rates if these precautions are properly addressed.
