Abstract:
Artificial breathing apparatus such as oxygen masks involves added external respiratory dead space. In dogs with permanent tracheostomies, chronic increase in dead space has been maintained with lengths of 0.75-inch interior diameter vinyl plastic tubing. A dead space of 2030 cc./kg. is not tolerated for more than 24 hours. The amount of mixing and air streaming within this tubing and in tubing of 0.5-inch interior diameter and 1.5-inch interior diameter was determined. There was very little mixing in the two smaller tubes but, in the large one, the amount of mixing was significant.
