title: User experience network. Supply gas failure alarm on Cardinal Health Infant Flow SiPAP units may not activate.
abstract: The supply gas failure alarm on Cardinal Health Infant Flow SiPAP units manufactured before April 2009 may not activate in the event of a gas supply loss if the device's silencer accessory is attached. However, the unit's FiO2 (fraction of inspired oxygen) and low-airway-pressure alarms will activate in such cases. If both of these alarms activate simultaneously, users should suspect a failure of the gas supply pressure. Identifying affected units requires testing that can be conducted during the device's next scheduled maintenance.
