Nonchemical influence of inspiratory pressure support on inspiratory activity in humans.
To determine whether nonchemical inhibition of respiratory activity occurs during inspiratory pressure support (IPS) ventilation (IPSV), respiratory motor output (in 9 subjects), obtained by calculating transdiaphragmatic pressure-time products, and central respiratory output (in 5 subjects), obtained by integrating the electromyographic activity of the diaphragm (EMGdi) during mechanical inspi...

I) ual drives affect breathing: chemical drives arising from the activity of central and peripheral chemoreceptors link ventilation with metabolic changes in the body; and nonchemical drives originating from mechanoreceptors located mainly in the thorax monitor the performance of the chest bellows and allow respiratory motor output to be adjusted as performance varies. Major subgroups of these ...

The mechanisms generating intrinsic or auto-positive end-expiratory pressure (PEEP) during controlled mechanical ventilation in a relaxed patient also occur during spontaneous breathing or when the patient triggers the ventilator during an assisted mode [1, 2]. These include an increased time constant for passive exhalation of the respiratory system, a short expiratory time resulting from a rel...
متن کاملThe Effects of Music Therapy on Respiratory Comfort, Anxiety, and Depression During Non-Invasive Mechanical Ventilation Among Patients with Coronavirus Disease
Background: Hospitalized patients with Covid-19 may experience emotional problems and respiratory discomfort during mechanical ventilation. The aim of this study was to evaluate the effects of music therapy on respiratory comfort, anxiety, and depression among patients with Covid-19 under non-invasive mechanical ventilation. Methods: It was a randomized clinical trial. The subjects were 64 pat...
متن کاملVentilation response and drive during hypoxia in adult patients with asthma.
We studied ventilation and inspiratory muscle activity during progressive isocapnic hypoxia in adult asthmatic patients to determine whether the decreased hypoxic ventilatory response previously identified is due to the mechanical abnormalities of the respiratory system or to low respiratory center output. The mouth pressure produced by inspiratory muscle activity, a reflection of respiratory c...
