PURPOSE OF REVIEW: Several alternative treatments have been proposed to decrease mortality of patients with acute respiratory distress syndrome (ARDS). We will discuss most recent trials and meta-analysis studies on nonconventional ventilatory and pharmacological treatments of ARDS patients. RECENT FINDINGS: Nonconventional ventilatory...

Purpose of review We report on recent advances and achievements on the use of extracorporeal gas exchange for long-term application in the therapy of critically ill patients with various forms of respiratory failure. Recent findings The most important results regarding the use of extracorporeal gas exchange are expected from the Conventional...

Mechanical ventilation and ventilator-associated lung injury could be avoided by decreasing the ventilatory needs of the patient by extracorporeal carbon dioxide removal. The reasons for the increased ventilatory needs of the patients with acute respiratory distress syndrome are outlined, as well as some of the mechanisms of continuing damage....

Computerised tomography (CT) is being used with increasing frequency in acute respiratory distress syndrome (ARDS) patients. This brief review will discuss some of the clinical insights that a CT scan can offer. A large number of CT scan studies have provided new insights into the pathophysiology of ARDS and of mechanical ventilation, and are...

Objective: To assess the behavior of different helmets after discontinuation of fresh gas flow by disconnection at the helmet inlet, flow generator, or gas source. Design and setting: Randomized physiological study in a university research laboratory. Patients: Five healthy volunteers. Intervention: CPAP (FIO250%, PEEP 5 cmH2O) delivered in...

Objective: To assess selected physiological effects of non-invasive continuous positive airway pressure delivered by head helmet (CPAPH), a special interface device designed to completely contain the head of the patient, compared to face mask (CPAPM). Design: Randomized physiological study. Setting: University research laboratory. Patients:...

We report a case of severe posttraumatic acute respiratory distress syndrome (ARDS) complicated by bronchopleural fistulae (BPF). The stiff ARDS lung and huge air leaks from BPF resulted in the failure of different protective mechanical ventilation strategies to provide viable gas exchange. Lung rest, achieved by extracorporeal carbon dioxide...

Purpose: The purpose of this study is to describe and test a modified Boussignac system for non-invasive continuous positive airway pressure, aimed at reducing the decrease in inspiratory oxygen fraction (FiO2) with higher inspiratory peak flow rates. Methods: We modified a Boussignac circuit by inserting a T-piece between the Boussignac valve...

Objective: We measured pulmonary edema by thermal indocyanine green-dye double-dilution technique and quantitative computed tomography (CT) in patients with acute respiratory distress syndrome and compared the two techniques. Design and Setting: Prospective human study in a university hospital. Patients: Fourteen mechanically ventilated...

Objective: It is commonly assumed that lung volume at zero end-expiratory pressure (functional residual capacity) is not affected by positive end-expiratory pressure (PEEP) even in presence of alveolar recruitment, and it is often ignored when measuring lung recruitment by pressure-volume curves. Aim of the study was to investigate the effect...

Objective: To prevent gas exchange deterioration during translaryngeal tracheostomy (TLT) in patients with acute respiratory distress syndrome (ARDS) ventilation is maintained through a small diameter endotracheal tube (ETT; 4.0 mm i.d.) advanced beyond the tracheostoma. We report on the feasibility of uninterrupted ventilation delivered...
