STUDY OBJECTIVES The purpose of the present study was to compare in awake and asleep healthy subjects, under nasal intermittent positive pressure ventilation (nIPPV) with a two-level intermittent positive pressure device (two-level nIPPV), the efficacy of the controlled and spontaneous modes, and of different ventilator settings in increasing effective minute ventilation (VE). PARTICIPANTS Ei...
Severe respiratory failure in a patient with obstructive sleep apnoea was treated successfully with nasal intermittent positive pressure ventilation. Nasal intermittent positive pressure ventilation is a non-invasive method of respiratory support originally developed for the treatment of chest wall and neuromuscular disorders.'2 Recent studies suggest that this technique may be applicable to a ...
The present study was aimed at investigating the effects of nasal continuous positive airway pressure (nCPAP; 6 cmH2O) or intermittent positive pressure ventilation (nIPPV; 10/4 cmH2O) on nonnutritive swallowing (NNS) and on the coordination between NNS and phases of the respiratory cycle, while taking into account the potential effects of states of alertness. Twelve full-term lambs were chroni...
Nocturnal ventilatory support in patients with cystic fibrosis: comparison with supplemental oxygen.
Progressive deterioration of lung function in cystic fibrosis (CF) patients may lead to significant hypoxaemia and hypercapnia, especially during sleep. The effects of bi-level noninvasive positive pressure nasal mask ventilation (NIPPV) on respiration and sleep were compared to those of low-flow oxygen therapy in six CF patients (mean +/- SD age 22.3 +/- 4.7 yrs, with severe lung disease (forc...
Cheyne-Stokes respiration (CSR) is common in patients with congestive heart failure (CHF). This characteristic crescendo-decrescendo pattern of breathing is often seen during sleep in patients with CHF and is a form of central sleep apnoea. Disordered nocturnal breathing leads to oxygen desaturation, poor sleep quality, and altered sleep architecture. These features may lead to complaints of da...
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 ...
BACKGROUND Nasal intermittent positive pressure ventilation (NIPPV) is useful in exacerbations of chronic obstructive pulmonary disease (COPD) complicated by ventilatory failure. The effects of NIPPV were compared with those of the respiratory stimulant doxapram on gas exchange in patients with COPD and acute ventilatory failure. METHODS Patients admitted with acute exacerbations of COPD and ...
