• being further characterized in that the breathing equipment is assembled from a set at least comprising the breathing bag (12) formed with remotely situated gas flow connecting apertures, the exhaust gas discharge bridging conduit (18), the gas guiding tube (16), and a gas redirecting connector (14) along which a gas transfer and breathing bag discharging passage (34, 40) forming part of the gas guiding conduit is defined thus in conjunction with the gas guiding tube (16) forming the gas guiding conduit;
• and

A breathing equipment set assembleable into breathing equipment (10) at least employable for use in anesthesiology procedure comprising:
