BACKGROUND Intermittent positive pressure ventilation applied through a nasal mask has been shown to be useful in the treatment of chronic respiratory insufficiency. Pressure support ventilation is an assisted mode of ventilation which is being increasingly used. Invasive ventilation with intermittent positive pressure, with or without positive end expiratory pressure (PEEP), has been found to ...

Pressure support ventilation (PSV) is a pressure assist form of mechanical ventilatory support that augments the patient's spontaneous inspiratory efforts with a clinician selected level of positive airway pressure. To understand the effects of PSV on respiratory function, experiments were performed on 15 stable patients requiring synchronized intermittent mandatory ventilation (SIMV), as well ...

Noninvasive ventilation (NIV) is recognized nowadays as the first choice of treatment for COPD exacerbation. Compared with standard medical treatment, it can significantly reduce the intubation rate, hospital stay, nosocomial infection, and, above all, mortality rate.1,2 Physiological studies have shown that the mechanism of action of NIV in this population is the ability to sustain alveolar ve...

To the Editor:—I read with interest the study by Jaber et al. and the accompanying editorial by Tantawy and Ehrenwerth regarding pressure-support ventilation (PSV). The Jaber study is noteworthy for documenting that the performance of PSV using modern anesthesia ventilators approaches the performance of an intensive care unit ventilator. The editorial correctly indicates that the testing was no...

ion techniques to validate and smooth the input data. In addition to providing treatment advice to clinicians, several IDSSs can also be used for closed-loop control of ventilation and/or weaning, while others are strictly open-loop knowledge-based

INTRODUCTION During pressure support ventilation (PSV) a part of the breathing pattern is controlled by the patient, and synchronization of respiratory muscle action and the resulting chest wall kinematics is a valid indicator of the patient's adaptation to the ventilator. The aim of the present study was to analyze the effects of different PSV settings on ventilatory pattern, total and compart...

C ontemporary homes can include a number of electrical devices aimed at making life easier, such as washing machines, dishwashers and vacuum cleaners. One can also find devices aimed at improving lifestyle, such as exercise bicycles or rowing machines. However, one can also find other types of devices that are aimed at supporting or saving people's life. These can include continuous positive ai...
