BACKGROUND Some patients started on nasal intermittent positive pressure ventilation (NIPPV) with the Monnal D ventilator deteriorate after a period. The effects of changing them to the Nippy ventilator were investigated. METHODS The records of such patients were examined retrospectively. Comparisons were made between blood gas tensions and overnight oximetry records before NIPPV, 12 weeks af...

OBJECTIVE To detail the history, modes, physiological effects, and circuit geometry of non-invasive ventilation. DATA SOURCES A review of articles published in peer-reviewed journals from 1966 to 1998 and identified through a MEDLINE search on non-invasive ventilation. SUMMARY OF REVIEW Non-invasive ventilation (NIV) has been used for many years as an adjunct to standard therapy in patients...

OBJECTIVE To assess the outcome of 54 patients with obesity-hypoventilation syndrome (OHS) who were treated with nasal intermittent positive-pressure ventilation (NIPPV). DESIGN Descriptive analysis of retrospectively collected clinical data. MATERIALS AND METHODS From March 1995 to December 2002, OHS (defined as a body mass index [BMI] of > 30 kg/m2, a daytime Pa(CO2) of > or = 50 mm Hg, a...

BACKGROUND Domiciliary assisted ventilation, using negative or positive pressure devices, is an effective treatment for respiratory failure due to chest wall deformity and neuromuscular disease. Negative pressure ventilators have been used with some success in patients with chronic obstructive lung disease in hospital, but attempts to continue treatment at home have been disappointing. This stu...

In selected patients, noninvasive positive pressure ventilation (NIPPV) with a facemask is now commonly employed as the first choice for providing mechanical ventilation in the intensive care unit (ICU). Aerosol therapy for treatment of acute or acute-on-chronic respiratory failure in this setting may be delivered by pressurized metered-dose inhaler (pMDI) with a chamber spacer and facemask or ...

Thorax Editorials Domiciliary ventilation in chronic obstructive pulmonary disease: where are we? The introduction of non-invasive nasal positive pressure ventilation (NIPPV) in the late 1980s has been a major advance in the home management of patients with chronic hypercapnic respiratory failure due to chest wall and neuro-muscular disease.`3 Nasal ventilation is considerably easier to adminis...

Non-invasive positive pressure ventilation (NIPPV) for respiratory failure in cystic fibrosis (CF) is frequently used in adults and has been shown to be of benefit to patients with advanced disease in terms of stabilisation of lung function, reduction in symptoms and increased exercise capacity. When used as an adjunct to physiotherapy, NIPPV increases oxygen saturations (SpO2), tidal volume, m...

BACKGROUND Noninvasive ventilation (continuous positive airway pressure [CPAP] or noninvasive intermittent positive-pressure ventilation [NIPPV]) appears to be of benefit in the immediate treatment of patients with acute cardiogenic pulmonary edema and may reduce mortality. We conducted a study to determine whether noninvasive ventilation reduces mortality and whether there are important differ...
