OBJECTIVE Recent studies provide evidence that nasal intermittent positive pressure ventilation (NIPPV) may stabilize the airway of extremely low birth weight infants after endotracheal extubation. The objective of this project was to introduce the use of NIPPV into a busy level 3 intensive care nursery. METHODS This report describes the process of NIPPV introduction using a series of rapid-c...

BACKGROUND Respiratory failure is the commonest cause of death in patients with Duchenne muscular dystrophy (DMD). Life expectancy is less than one year once diurnal hypercapnia develops. This study examines the effects of nasal intermittent positive pressure ventilation (NIPPV) on survival in symptomatic Duchenne patients with established ventilatory failure. METHODS Nocturnal NIPPV was appl...

Nasal continuous positive airway pressure (NCPAP) has proven to be an effective mode of non-invasive respiratory support in preterm infants; however, many infants still require endotracheal ventilation, placing them at an increased risk of morbidities such as bronchopulmonary dysplasia. Several other modes of non-invasive respiratory support beyond NCPAP, including synchronised and non-synchron...

A 49 yr old poliomyelitic patient had been under cuirass-type nocturnal negative pressure ventilation for more than 20 yrs. He had a severe restrictive ventilatory impairment, and normal awake blood gases at rest and during light exercise. He was offered a trial of intermittent positive pressure ventilation applied through the nose (nIPPV). Two daytime studies and one night study were carried o...

Nocturnal nasal intermittent positive pressure ventilation (nIPPV) has been used successfully in the management of patients with respiratory failure due to chest wall deformity and neuromuscular disease. In order to determine if nIPPV is useful in patients with cystic fibrosis (CF) complicated by respiratory failure, we treated four hypercapnic patients for up to 18 months. All patients had fai...

Bronchopulmonary dysplasia (BPD), also known as chronic lung disease (CLD), is the most common serious morbidity associated with premature birth, particularly among those infants who have respiratory distress syndrome (RDS) and receive mechanical ventilation after birth. BPD is characterized by lung inflammation and scarring, which are thought to be the effects of excessive (or inadequate) vent...

BACKGROUND Apnoea, desaturations and bradycardias are common problems in preterm infants which can be treated with nasal continuous positive airway pressure (NCPAP) and nasal intermittent positive pressure ventilation (NIPPV). It is unclear whether synchronised NIPPV (SNIPPV) would be even more effective. OBJECTIVE To assess the effects of flow-SNIPPV, NIPPV and NCPAP on the rate of desaturat...

The present study aimed to assess the impact of diurnal mouthpiece intermittent positive pressure ventilation (MIPPV) as the extension of the nasal intermittent positive pressure ventilation (NIPPV) in Duchenne muscular dystrophy (DMD). In total, 42 DMD patients aged 15-33 yrs, normocapnic at night with NIPPV and receiving MIPPV since end-diurnal hypercapnia, were studied. Transcutaneous CO2 te...

When supplementary oxygen is necessary with nasal intermittent positive pressure ventilation (NIPPV), the optimal route by which it should be added to the ventilator circuit is unknown. We investigated the oxygen concentration received when oxygen was supplied at flow rates between 0 and 6 L.min-1 into the proximal ventilator tubing or the nasal mask whilst patients were ventilated with air. El...

BACKGROUND A study was undertaken to assess the long term physiological and clinical outcome in 79 patients with musculoskeletal disorders (73 neuromuscular, six of the chest wall) who received non-invasive ventilation for chronic respiratory failure over a period of 46 years. METHODS Vital capacity (VC) and carbon dioxide tension (PCO(2)) before and after initiation of ventilation, type and ...
