Determination of CO2 and O2 at Various Stages of the Dives Using Three Different Types of Self Contained Breathing Apparatus under Identical Conditions and the Appraisal of Them from a Standpoint of Comfort, Breathing Resistance, Duration, Visability and Other Factors Pertinent to their Practical Use

Abstract

The object of this experiment is to determine the CO2 and O2 at various stages of the dives of various self contained breathing apparatus under identical conditions and to appraise them from a standpoint of comfort, breathing resistance, duration, visibility and other factors pertinent to their practical use.
