NOxBOXi Nitric Oxide Delivery System is intended for use by healthcare professionals for the delivery and monitoring of a constant (user set) concentration of nitric oxide (NO) and the monitoring of N02 and 02 in the inspiratory ventilator lines of a patient undergoing nitric oxide therapy (iNO).
The NOxBOXi Nitric Oxide Delivery System includes:
* The NOxBOXi head unit, which delivers NO gas while in the intelligent delivery mode.
* Continuous monitoring and alarms for NO, 02 and N02.
* The integrated NOxMixer which provides a backup NO delivery capability that is intended to deliver a continuous flow of NO, mixed with 02, for iNO therapy and provides a continuous treatment option during transit and transfer conditions within hospitals.
The NOxBOXiNitric Oxide Delivery System must only be used in accordance with the indications, contraindications, warnings and precautions described in the nitric oxide drug packaging inserts and labeling (currently neonates). Refer to this material prior to use.
Indications for use as stated in the FDA summary.
