Important
Before using the INOvent delivery system, read through this manual and the related manuals provided. Read through the manuals for the ventilator, humidifier and any other accessory items used. Follow the manual instructions and obey Warnings and Cautions. Know the proper setup and operation of the ventilator and the humidifier you are using. Know the proper information provided in this Operation and Maintenance manual before operating the INOvent delivery system. Keep this manual readily available to answer questions. Read through each step or procedure to understand it before doing it. All specifications in this manual are nominal. Read the User Responsibility statement on the inside front cover of this manual; it describes what the user must do to maintain this product.
w WARNING
The INOvent delivery system must only be used in accordance with the indications, usage, contraindications, warnings and precautions described in the nitric oxide drug package inserts and labeling. Drug package inserts and labeling are packaged with each drug cylinder. Refer to this material prior to use. The use of devices which radiate high-intensity electrical fields may affect the operation of the delivery system. Do not drape the leads of these devices across the delivery system. Constant surveillance of all monitoring and life support equipment is mandatory whenever interfering devices are in operation on or near a patient.

INOvent delivery system
Overview • The INOvent delivery system delivers nitric oxide therapy gas into the inspiratory limb of the patient breathing circuit in a way that provides a constant concentration of NO, as set by the user, to the patient throughout the inspired breath. • The INOvent delivery system uses a specially designed Injector Module which enables the tracking of ventilator waveforms and the delivery of a synchronized and proportional dose of NO. • The INOvent delivery system may be used with most ventilators. • The INOvent delivery system provides continuous on-line integrated monitoring of delivered O2, NO2, and NO, and a comprehensive alarm system. • The interactive control panel and display provide a simple-tounderstand interface for operation of the INOvent delivery system. • The battery system provides up to 30 minutes of uninterrupted nitric oxide delivery in the absence of an external power source. • The INOvent delivery system provides an integrated Manual NO delivery system for administration of a fixed concentration of NO/O2 therapy with a resuscitator bag.
