Positive 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 کاملAutomatic monitoring of plateau and driving pressure during pressure and volume controlled ventilation
Objectives To evaluate the feasibility of ΔP and Pplat continuous monitoring during volume (VCV) and pressure (PCV) controlled ventilation, we compared with gold standard (occlusion maneuvers at end-inspiration and end-expiration) two different methods: 1Least Square Fitting (LSF) method that provide maneuver-free Pplat and ΔP values; 2Mini Occlusion (MO) method by performing brief occlusion ma...
متن کاملPressure-controlled ventilation and intrabronchial pressure during one-lung ventilation.
BACKGROUND Pressure-controlled ventilation (PCV) has been suggested to reduce peak airway pressure (P(peak)) and intrapulmonary shunt during one-lung ventilation (OLV) when compared with volume-controlled ventilation (VCV). At the same tidal volume (V(T)), the apparent difference in P(peak) is mainly related to the presence of a double-lumen tracheal tube. We tested the hypothesis that the decr...
متن کاملPressure vs flow triggering during pressure support ventilation.
BACKGROUND Adult mechanical ventilators have traditionally been pressure- or time-triggered. More recently, flow triggering has become available and some adult ventilators allow the choice between pressure or flow triggering. Prior studies have supported the superiority of flow triggering during continuous positive airway pressure, but few have compared pressure and flow triggering during press...
متن کاملReducing tidal volume and increasing positive end-expiratory pressure with constant plateau pressure during one-lung ventilation: effect on oxygenation.
BACKGROUND It is no longer safe to use large tidal volumes (V(T)) (>8 ml kg(-1)) for one-lung ventilation (OLV), and limiting plateau pressure should be a major objective. Due to the specificity of OLV, the use of positive end-expiratory pressure (PEEP) remains controversial. This study determined whether at the same low plateau pressure, reducing V(T) and increasing PEEP were not inferior to l...
