BACKGROUND Noninvasive ventilation (NIV) in preterm infants is currently applied using intermittent positive pressure (2 positive-pressure levels) or in a conventional manner (one pressure level). However, there are no studies in the literature comparing the chances of failure of these NIV methods. The aim of this study was to evaluate the occurrence of failure of 2 noninvasive ventilatory supp...

Background: Early nasal continuous positive airway pressure (NCPAP) has emerged as a primary modality of respiratory support for preterm infants withrespiratory distress syndrome (RDS). However, 30%-40% of these newborns need subsequent mechanical ventilation. Nasal intermittent positive pressure ventilation (NIPPV) is a promising alternative to NCPAP, especially in po...

OBJECTIVES The Severe Respiratory Insufficiency (SRI) questionnaire is the best assessment tool for health-related quality of life in patients with chronic obstructive pulmonary disease (COPD) receiving non-invasive positive pressure ventilation (NIPPV). This study aimed to translate the SRI Questionnaire into Chinese and to validate it. DESIGN Prospective validation study. SETTING AND PART...

The aim of our study was to evaluate the long-term effect of nasal ventilation in patients with advanced Duchenne's muscular dystrophy (DMD). To this end, we compared the clinical and pulmonary function course of five subjects affected with chronic ventilatory failure due to DMD and treated with nasal intermittent positive pressure ventilation (NIPPV) with that of an unventilated comparison gro...

Main text We read the innovative study by Duan et al. [1] with great interest. However, key results need to be interpreted carefully to reach the proper conclusions. First, their primary finding that patients with low cough peak expiratory flow (CPEF) have significant benefit from non-invasive positive pressure ventilation (NIPPV) in the prevention of re-intubation and 90-day mortality is not u...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2017219201 DESCRIPTION A male patient aged 81 years reported with dyspnoea and loss of consciousness, at our emergency department. His respiratory rate was 30 breaths/ min, and his level of consciousness determined using the Glasgow Coma Scale was eye (1), verbal (1) and mot...

OBJECTIVES To determine the effects of long-term nocturnal intermittent positive-pressure ventilation (NIPPV) on symptoms, pulmonary function test results, sleep, and respiratory muscle performance in patients with ventilatory insufficiency due to severe kyphoscoliosis. DESIGN A prospective study in which 16 severe kyphoscoliotic patients were treated with NIPPV delivered by volume-cycled and...

BACKGROUND Near-infrared spectroscopy (NIRS) provides the capability of monitoring oxygenation levels in cerebral microscopic vessels, enabling the operator to observe the spontaneous changes in the levels of hemoglobin concentration in tissue and interpret the resulting fluctuations. The current study tried to investigate whether brain's autoregulatory mechanisms in premature newborns have the...

Introduction: Although patients with an acute increase in airflow resistance may require aerosol therapy and noninvasive positive pressure ventilation (NIPPV), the efficiency of different aerosol devices and masks during NIPPV is not well understood. The purpose of this study was to determine the efficiency of a jet nebulizer (JN), a vibrating mesh nebulizer (VMN) and a pressurized metered-dose...
