BACKGROUND A high flow of air applied by large bore nasal cannulae has been suggested to improve symptoms of chronic respiratory insufficiency. In pediatric patients, nasal high-flow (nHF) ventilation was similarly effective compared to noninvasive ventilation with a face mask. OBJECTIVES The aim of this study was to describe changes in respiratory parameters. METHODS We measured pressure a...

BACKGROUND Respiratory effort belt measurement is a widely used method to monitor respiration. Signal waveforms of respiratory volume and flow may indicate pathological signs of several diseases and, thus, it would be highly desirable to predict them accurately. Calibrated effort belts are sufficiently accurate for estimating respiratory rate, but the respiratory volume and flow prediction accu...

Objective Structural deformities can impair different body functions, and kyphosis is one of the most common postural deformities. It seems that kyphosis induces unfavorable effects on the respiratory system. Impairment of pulmonary function, in turn, affects spirometer indices significantly. Some previous studies have indicated a positive influence of corrective structural exercise on kyphosis...

PURPOSE OF REVIEW The aim of this article is to describe the physiologic utility, correlation with lung morphology, difficulties in interpretation and current clinical applications of static respiratory system pressure-volume curves at the bedside in patients with acute lung injury or acute respiratory distress syndrome. RECENT FINDINGS Complex interpretation of pressure-volume curves indicat...

High case volume is associated with improved survival in medical and surgical conditions. The present study sought to determine whether intensive care unit (ICU) case volume was associated with survival of critically ill patients with haematological malignancies and acute respiratory failure (ARF). A regional database containing data from 1,753 haematological patients with ARF admitted to 28 me...

Introduction The distribution of viable and infarcted myocardium is typically visualized using inversion recovery (IR) late gadolinium enhancement (1) or phase-sensitive inversion recovery (PSIR) sequences (2). Transitioning PSIR from breath-hold 2D to respiratory navigator-gated 3D imaging promises higher SNR and CNR, and whole heart coverage (3,4). However, the optimal method for motion compe...

BACKGROUND The authors studied the effects of the beach chair (BC) position, 10 cm H2O positive end-expiratory pressure (PEEP), and pneumoperitoneum on respiratory function in morbidly obese patients undergoing laparoscopic gastric banding. METHODS The authors studied 20 patients (body mass index 42 +/- 5 kg/m2) during the supine and BC positions, before and after pneumoperitoneum was institu...

Background: Occupational flour inhalation has been a culprit in commence of several pulmonary maladies, such as asthma. The flour particle is one of the most important factors which can cause occupational chronic respiratory disorders. We examined the relationship of occupational wheat flour inhalation in bakery and supermarket employees with pulmonary function, respiratory symptoms, and sputum...

BACKGROUND The burden and determinants of airway disease in the population of southern Africa, which is currently undergoing rapid, often uncontrolled, urbanisation and industrialisation, are unknown. Previous surveys have focused on specific occupational groups and few have included women. This paper describes the respiratory status in a 30% probability sample of 206 men and 203 women drawn fr...
