The MBW Pre-Training module provides background information about the multiple breath nitrogen washout in preparation for the 1-day hands-on training session with the Exhalyzer® D held at The Hospital for Sick Children. All participants are encouraged to review the pre-training lessons to familiarize themselves with the MBW test and Exhalyzer® D equipment. After completing the lessons proceed to the pre-training quiz.

The MBW Post-Training module includes two additional MBW lessons and should be completed after attending our one day hands on session.
