Neurally-Adjusted Ventilatory Assist for Noninvasive Ventilation via a Helmet in Subjects With COPD Exacerbation: A Physiologic Study

Longhini F, Liu L, Pan C, et al. Respir Care. 2019;64(5):582-589

In this study compared neurally-controlled pressure support through a helmet with pressure support through a face mask for subject comfort, breathing pattern, gas exchange, pressurization and triggering performance, and patient-ventilator synchrony. Two 30-min trials of NIV were randomly delivered to 10 subjects with COPD exacerbation. The first group was treated with pressure support through a face mask and the second group with NAVA through a helmet. Several parameters were evaluated including subject comfort, breathing frequency, respiratory drive, arterial blood gases, pressure-time product (PTP) of the first 300 ms and 500ms after initiation of subject effort, inspiratory trigger delay, and rate of asynchrony determined as the asynchrony index. NAVA through a helmet significantly improved comfort compared with pressure support through a face mask. Although the breathing pattern was not different between the methods, the respiratory drive was slightly reduced during NAVA through a helmet in comparison with pressure support through a face mask. Gas exchange was also not different between the trials. The PTP was comparable between trials, whereas triggering performance, patient-ventilator interaction, and synchrony were all improved by NAVA through a helmet compared with pressure support through a face mask. Therefore, in subjects with COPD with exacerbation, NAVA through a helmet improved comfort, triggering performance, and patient-ventilator synchrony compared with pressure support through a face mask.

Non-invasive ventilation delivered by conventional interfaces and helmet in the emergency department

Pelosi P, Severgnini P, Aspesi M, Gamberoni C, Chiumello D, Fachinetti C, Introzzi L, Antonelli M, Chiaranda M. Eur J Emerg Med. 2003 Jun;10(2):79-86.

Early review of the use of NIV and the helmet interface in the emergency department and in the pre-hospital setting. Authors concluded that the helmet 'can extend the application of non-invasive positive pressure ventilation in different categories of patients with respiratory failure'.
