summary ventilation treatment system and method for providing a treatment gas flow this revelation belongs to a ventilation treatment system configured to sterilize and/or disinfect a fluid path by mea ventilator by providing a forced flow of treatment gas to the ventilator. Fans are often contaminated by bacteria and viruses during normal use. when a fan is transferred from one patient to anotherThere is a risk of contamination of the new patient by the pathogen of the previous patient. The application of treatment gas is especially practical for the hygienisation of surfaces difficult to access, such as those found in cavities and ducts (the way of the fluid) of a ventilator. a treatment gas, such as ozone, is converted to oxygen and has a short life span, which can be further reduced by humidity, heat, or cheap destruction catalysts. this revelation applies to any medical device with a fluid path that can be contaminated,provided that the materials in the path of the fluid in the medical device are compatible with the sterilisation and/or disinfection gas. In one realisation, the ventilator sterilization system comprises one or more treatment gas flow generators, a gas circuit, a user interface, one or more sensors, a treatment gas remediation system, an exhaust port, one or more valves, a processor, electronic storage, and/or other components. 1/1resumo sistema de tratamento com ventilador e método para o provimento de um fluxo de gás de tratamento a presente revelação pertence a um sistema de tratamento com ventilador configurado para esterilizar e/ou desinfetar um caminho de fluido por meio de um ventilador pelo provimento de um fluxo forçado de gás de tratamento para o ventilador. os ventiladores são frequentemente contaminados por bactérias e vírus durante o uso normal. quando um ventilador é transferido de um paciente para outro, existe o risco da contaminação do novo paciente pelo patógeno do paciente anterior. a aplicação de gás de tratamento é especialme
