Assessment of NeuroBOX and NeuroPAP in Infants.

Clinical Assessment of the NeuroBOX, a Cardio-respiratory Monitor Combined With a Fully Neurally Controlled Non-invasive Ventilator, in Infants.

Non-invasive ventilation (NIV, delivered via a mask or cannulas) permits to reduce the need for tracheal intubation in infants who needs a ventilatory support. NIV can be delivered with nasal CPAP (continuous positive airway pressure) or NIPPV (nasal intermittent positive pressure ventilation). The synchronization of the respiratory support according to the patient's demand is very difficult to obtain in infants with the conventional ventilatory modes. In all these ventilatory modes, the end-expiratory pressure (PEEP) is fixed and set by the clinician. However, since infants are prone to alveolar collapse and must compensate for a non-compliant chest wall, an active and ongoing management of PEEP is very important to prevent the lung de-recruitment. A new respiratory support system (NeuroPAP) has been developed to address these issues of synchronization and control of PEEP. This new system uses diaphragmatic tonic activity (Edi) that reflects the patient's efforts to increase lung recruitment and therefore it continuously controls the delivery of assist continuously both during inspiration (like NAVA) and during expiration, allowing a unique neural control of PEEP. A new device, the NeuroBOX, permits to deliver NIV with NeuroPAP, CPAP, or NIPPV, and also to serve as a cardio-respiratory monitor, tracking and displaying cardiac and respiratory signals, trends, and cardio-vascular events. The two main objectives of this study are: 1- To evaluate the clinical impact of NeuroPAP in infants with high tonic Edi; 2- To characterize the cardio-respiratory pattern and its relationship with cerebral perfusion of infants with noninvasive support, using the monitoring capacity of the NeuroBOX. The investigators expect that NeuroPAP will permit to improve the efficiency of NIV in infants, through the better synchronization and the personalization of the expiratory pressure level in response to the patient needs. This study will be conducted in two subgroups of patients at high risk of elevated tonic Edi and of cardio-respiratory events: a subgroup of premature infants and a subgroup of infants with bronchiolitis.
