The integrated Backup NO delivery system is a completely independent backup NO generating system that is separate from the main delivery system; it has its own NO generator and gas flow delivery system. Backup NO flow can be delivered to one of two different locations by using the System Selector switch located on the front panel of the LungFit PH system.When the Selector Switch is turned to “Bagging System” position, the backup NO module turns on and delivers 1 L/min of 220 ppm of NO through a separate internal NO2 filter to the Bagging System connector on the front panel of the LungFit PH system. The Bagging System connector has two tubing fittings: one for connecting to an air/oxygen source through oxygen tubing or equivalent to provide an external flow of air/oxygen and the other to connect to a manual resuscitator for manually ventilating a patient. The 1 L/min NO flow from the backup NO module is added to this air/oxygen flow which dilutes the NO concentration down to therapeutic levels. Final NO concentration will depend on the amount of external flow added; for example, a flow of 10 L/min will provide 20 ppm of NO to the patient.
A mains electricity (AC-powered) device, which may include internal rechargeable batteries, intended for the delivery of precise amounts of nitric oxide (NO), also known as nitrogen monoxide, to the respiratory tract of neonate, paediatric, and adult patients to treat severe respiratory disorders [e.g., primary pulmonary hypertension (PPH), acute respiratory distress syndrome (ARDS)]. It consists of a portable main unit that enables the delivery and monitoring of NO to gases that are to be breathed by the patient via a ventilator or other respiratory device/system. It typically includes accessory items (e.g., tubing, filters) and possibly a trolley (cart) for mobility.
