Questions and Answers


Can Intersurgical Breathing Filters be used with Ambu SPUR II Resuscitators?

Lucia M.- On Monday, 23 November 2020


The preferred location for a filter on an Ambu SPUR II Resuscitator is the exhalation port which would require a 30mm adapter. This filter will fit between the valve and mask, but you should consult with your medical director before using a filter this way. It will increase dead space, and can accumulate moisture.
