Mechanisms of active laryngeal closure during noninvasive intermittent positive pressure ventilation in nonsedated lambs.
The present study stems from our recent demonstration (Moreau-Bussiere F, Samson N, St-Hilaire M, Reix P, Lafond JR, Nsegbe E, Praud JP. J Appl Physiol 102: 2149-2157, 2007) that a progressive increase in nasal intermittent positive pressure ventilation (nIPPV) leads to active glottal closure in nonsedated, newborn lambs. The aim of the study was to determine whether the mechanisms involved in ...
متن کاملLaryngeal response to nasal ventilation in nonsedated newborn lambs.
Although endoscopic studies in adult humans have suggested that laryngeal closure can limit alveolar ventilation during nasal intermittent positive pressure ventilation (nIPPV), there are no available data regarding glottal muscle activity during nIPPV. In addition, laryngeal behavior during nIPPV has not been investigated in neonates. The aim of the present study was to assess laryngeal muscle...
متن کاملLaryngeal muscle activity during nasal high-frequency oscillatory ventilation in nonsedated newborn lambs.
BACKGROUND We have previously shown that nasal pressure support ventilation (nPSV) can lead to an active inspiratory laryngeal narrowing in lambs. This, in turn, can limit lung ventilation and divert air into the digestive system, with potentially deleterious consequences. On the other hand, nasal high-frequency oscillatory ventilation (nHFOV) is particularly attractive in newborns, especially ...
متن کاملNoninvasive Positive-Pressure Ventilation.
Prince Andrew married Sarah Ferguson on July 23 1986. That day also saw the first use in the United Kingdom of non-invasive positive pressure ventilation by nasal mask. Aged about fifty years, the patient had suffered pulmonary tuberculosis as a youngster and, in the days before antituberculous chemotherapy, had been treated with bilateral pneumothoraces, phrenic crush and finally an apical tho...
متن کاملDeterminants of effective ventilation during nasal intermittent positive pressure ventilation.
Our aim was to verify in healthy subjects submitted to nasal intermittent positive pressure ventilation (nIPPV) with a volumetric ventilator on controlled mode, whether changes in ventilator settings (delivered tidal volume (VT), respiratory frequency (fR) and inspiratory flow (V'I) could influence effective minute ventilation (V'E), thus allowing identification of the settings resulting in the...
