Noninvasive positive pressure ventilation (NPPV) is a technique used to deliver mechanical ventilation that is increasingly utilised in acute and chronic conditions. The present review examines the evidence supporting the use of NPPV in acute respiratory failure (ARF) due to different conditions. Strong evidence supports the use of NPPV for ARF to prevent(More)
Vascular disease is frequent in uremics and may contribute to tissue malnutrition and damage. The aim of this study was to detect whether uremic patients show also changes of microcirculation and to evaluate the effects induced by hemodialysis (HD) session. Eleven uremics on HD (7 males, 4 females, aged 25-65 years) were studied; 11 healthy subjects, age-(More)
OBJECTIVES To investigate the skin vasodilatory response to iontophoretically applied acetylcholine (Ach), an endothelium dependent vasodilator, and to sodium nitroprusside (SNP), an endothelium independent vasodilator, in patients with systemic sclerosis (SSc). METHODS Eleven SSc patients were preliminarily studied (10 females, mean age 40.5; mean(More)
The role of pulmonary rehabilitation (PR) in COPD patients with lung hyperinflation has not yet been fully investigated. We retrospectively evaluated the effect of a standard PR course on exercise tolerance and symptoms according to the presence or absence of associated lung hyperinflation, as defined by lung function parameters in three Italian(More)
Randomized controlled trials have confirmed the evidence and helped to define when and where non invasive mechanical ventilation (NIV) should be the first line treatment of acute exacerbations of chronic obstructive pulmonary disease (AECOPD). Noninvasive ventilation has its best indication in moderate-to-severe respiratory acidosis in patients with AECOPD.(More)
BACKGROUND Recently, it has been proposed that different clinical phenotypes can be recognized in patients with chronic obstructive disease (COPD), namely predominant airway disease or parenchymal destructive changes. OBJECTIVES The aim of this prospective multicenter study was to evaluate whether these two phenotypes may influence outcomes following a(More)
The aim of the present study was to assess the endothelial function of the microcirculation in chronic renal failure. We investigated the responses of the cutaneous blood flow to locally delivered acetylcholine and sodium nitroprusside in uremic patients. The study included 60 chronic uremic patients: 40 patients with a creatinine clearance of 4-25 ml/min(More)
Neurally adjusted ventilatory assist (NAVA) is a mode of ventilation wherein the delivered assistance is proportional to diaphragm electrical activity (EAdi) throughout inspiration. We assessed the physiologic response to varying levels of NAVA and pressure support ventilation (PSV) in 13 tracheostomised patients with prolonged weaning. Each patient(More)
In critically ill patients, a prolonged hospital stay, due to the initial acute insult and adverse side-effects of drug therapy, may cause severe late complications, such as muscle weakness, prolonged symptoms, mood alterations and poor health-related quality of life. The clinical aims of physical rehabilitation in both medical and surgical intensive care(More)
BACKGROUND Respiratory intermediate care units (RICU) are hospital locations to treat acute and acute on chronic respiratory failure. Dedicated weaning centers (WC) are facilities for long-term weaning. AIM We propose and describe the initial results of a long-term weaning model consisting of sequential activity of a RICU and a WC. METHODS We(More)
