Acute respiratory distress syndrome is characterized by diffuse inflammatory lung injury and is classified as mild, moderate, and severe. Clinically, hypoxemia, bilateral opacities in lung images, and decreased pulmonary compliance are observed. Sepsis is one of the most prevalent causes of this condition (30 - 50%). Among the direct causes of acute respiratory distress syndrome, chlorine inhal...

The use of noninvasive ventilation (NIV) in acute hypercapnic respiratory failure, cardiogenic pulmonary oedema, acute lung injury/acute respiratory distress syndrome (ARDS), community-acquired pneumonia and weaning/post-extubation failure is considered common in clinical practice. Herein, we review the use of NIV in unusual conditions. Evidence supports the use of NIV during fibreoptic broncho...

INTRODUCTION Noninvasive ventilation (NIV) is a standard procedure in selected patients with acute respiratory failure. Previous studies have used noninvasive ventilation to ensure adequate gas exchange during fiberoptic bronchoscopy in spontaneously breathing hypoxemic patients, thus avoiding endotracheal intubation. However, it is unknown whether bronchoscopy can be performed safely in patien...

The aim of the study was to comprehensively examine the efficacy and safety of noninvasive ventilation used at the pulmonary infection control (PIC) window for acute respiratory failure (ARF) in patients with acute exacerbations of chronic obstructive pulmonary disease (AECOPD).Seven electronic databases and relevant resources were searched to identify randomized controlled trials (RCTs) compar...

Nasal mask ventilation has been shown to be effective, but outcomes do not always match expectations because of mouth leaks, patient-ventilator asynchrony, or decreased upper airway patency. These developments are detected when they lead ultimately to circuit leaks that lower the effectiveness of ventilation through pressure loss, poor inspiratory triggering, and prolonged inspiratory time. The...

Current respiratory management paradigms recommend tracheotomy for ventilator-dependent patients. The review by SHNEERSON and SIMONDS [1] published in the European Respiratory Journal on the current use of noninvasive ventilation (NIV) in neuromuscular disorders does little to dispel this paradigm. The authors note that "nasal and face masks are usually the first choice" for NIV interfaces, and...

Objectives. To assess whether noninvasive ventilation with Heliox reduces the need for endotracheal ventilation and subsequent complications in preterm infants with respiratory distress syndrome (RDS). Methods. A search of major electronic databases, including MEDLINE and the Cochrane Central Register of Controlled Trials, for randomized or quasi-randomized controlled trials that compared nonin...

BACKGROUND Noninvasive positive pressure ventilation is frequently prescribed to obese patients with obstructive sleep apnea syndrome and obesity hypoventilation syndrome. However, mechanical ventilation with a positive end-expiratory pressure can induce or worsen a right-to-left shunt through a patent foramen ovale associated with systemic hypoxemia. Thus, in obese patients treated with noninv...

Noninvasive ventilation (NIV) and continuous positive airway pressure (CPAP) have been used in various unusual settings to assist breathing. NIV is now frequently used to treat exacerbations of chronic obstructive pulmonary disease and chronic respiratory failure in neuromuscular disease. This paper discusses CPAP and NIV for postoperative hypoxemia, preventing intubation in high-risk bronchosc...

HYPOTHESIS Albuterol delivered during noninvasive positive-pressure ventilation is affected by use of a nebulizer or metered-dose inhaler (MDI) and whether the leak port is in the hose or the mask. METHODS A lung model that simulated spontaneous breathing at 20 breaths/min was used. A bi-level positive-airway-pressure ventilator (Respironics S/T30) was set for an inspiratory positive airway p...
