Which of the following are true when heated-wire circuits are used with heated humidifiers ex-cept:

a. the humidifier operates at a higher tem-perature.
b. there is less condensate and a reduced need for drainage.
c. cost savings (less water and staff time) are realized.
d. there is less infection risk for both patient and caregivers.

ANS: A
When heated-wire circuits are used, the humidifier heats gas to a lower temperature (32° to 40° C) than it does with conventional circuits (45° to 50° C). The reduction in condensate in the tub-ing results in less water use, reduced need for drainage, and less infection risk for both patient and health care workers.
