FIELD: medicine.
SUBSTANCE: secondary line purging system comprises a blower for pressurising a flow of gas, a secondary line communicating with blower and a subject circuit, a first pressure sensor for measuring a first pressure of flow of gas at or near blower, as well as a second pressure sensor for measuring second pressure of flow of gas inside a secondary line. Valve system is operable in a first mode of operation to isolate the blower from secondary line and a second mode of operation to permit communication between blower to secondary line to purge secondary line of obstructions with pressurised flow of gas.
EFFECT: invention discloses a system and method of purging pressure line for an artificial pulmonary ventilation apparatus.
