Description: Regularity of flow at work in SCBA is a normal function of the distribution of the indicator within the considered mode. It is noted that in all operating modes of SCBA air flow above the normative parameters of pulmonary ventilation. Justified the use of the term "air flow" instead of "pulmonary ventilation". Proposed security guards at the post to assess the temporal characteristics of the calculated taking into account the actual values of the air flow. The main focus it needs to be addressed checking cylinder pressure of CSBA and permanent correction of controlling the pressure at which the units of rescuers should begin returning to fresh air.
