Response of Maximum Inspiratory Pressure and Functional Capacity to Positive End-Expiratory Pressure Device after Valvular Heart Surgery
Background: Pulmonary complications following valvular heart surgery are common and contribute to increased duration of hospital stay, rate of morbidity, and mortality. The purpose of the present study was to investigate the response of maximum inspiratory pressure and functional capacity to Positive End-Expiratory Pressure device in patients who underwent valvular hea...
متن کاملEffects of positive end expiratory pressure during ventilation of the preterm infant.
Twenty two babies receiving artificial ventilator support were studied on 29 occasions to determine the effects of low levels of positive end expiratory pressure. Mean positive end expiratory pressure during these studies was 2.6 cm H2O. Changes in tidal volume, minute volume, compliance, and transcutaneous gas trends produced by the use of positive end expiratory pressure were investigated. Po...
متن کاملInspiratory time and tidal volume during intermittent positive pressure ventilation.
We measured the tidal volume achieved during intermittent positive pressure ventilation using various inspiratory times with a minimum of 0.2 seconds. Results indicate that tidal volume shows no reduction with inspiratory times down to 0.4 seconds. An inspiratory time of 0.3 seconds, however, is likely to reduce tidal volume by 8%, and at 0.2 seconds a 22% fall may be anticipated.
متن کاملPositive expiratory pressure plateau: improved gas exchange during mechanical ventilation.
IT IS "WELL KNOWN that the pattern of mechanical ventilation can affect the efficiency of pulmonary gas exchange. Despite this, the optimum ventilatory wave form has yet to be defined. In the past, most research has pertained to the pattern of inspiration T M and relatively little attention has been directed to the expiratory phase of ventilation. The concept of a maintained expiratory pressure...
متن کاملHeterogeneity in ventilation during positive end-expiratory pressure
geneity in ventilation be good’ [1] and the related article by Zhao and colleagues [2]. We agree with the comments that instead of incremental positive end-expiratory pressure (PEEP) levels, a decremented PEEP titration might be an attractive option for determining optimal PEEP [1,3]. However, we feel that physiological inhomogeneity in ventilation and perfusion related to the gravitational eff...
