ABSTRACT

It is important to analyze the current state of a person during respiration in individual breathing apparatus. For that reason, you need to register cardiorespiratory parameters of a human. Reusable simulators of breathing apparatus with specific hardware and software are used for these purposes. They allow simulating the conditions of the breathing, equivalent to primary breathing apparatus with chemically bound oxygen.
During the development of the mine insulating self-rescuer simulator for the personnel of mining industries, the indicators of heart rate variability, spirography and pneumotachography were identified.
Based on the analysis of the requirements in the recorded parameters, a selection of control devices and measuring sensors was carried out, a diagram of the simulator hardware was developed, and information flows were formalized.
The graphic programming environment LabVIEW was selected as development environment. The paper presents the structure and functioning algorithms of the main program control units of the simulator which responsible for the generation of the specified breathing conditions

Keywords: spirography, pneumotachography, LabVIEW, self-rescuer, breathing apparatus.
