Dead space in the breathing apparatus; interaction with ventilation / D.E. Warkander and C.E.G. Lundgren

Sumario: Dead space in breathing apparatus may cause increased ventilation and/or CO2 retention. Interactions between ventilation and dead space tested in the breathing apparatus of three divers: a full face mask with an oro-nasal cul (AGA), a full face mask without an oro-nasal cup (EXO-26) but designed to minimize dead space, and one mouthpiece. Comparisons of the mean inspired PCO2 to the maximum values considered acceptable by various organizations showed that the mouthpiece was always acceptable, THe AGA mask was marginally acceptable or better, while sometimes the EXO-26 was not acceptable
