Clinical assessment of auto-positive end-expiratory pressure by diaphragmatic electrical activity during pressure support and neurally adjusted ventilatory assist.
BACKGROUND Auto-positive end-expiratory pressure (auto-PEEP) may substantially increase the inspiratory effort during assisted mechanical ventilation. Purpose of this study was to assess whether the electrical activity of the diaphragm (EAdi) signal can be reliably used to estimate auto-PEEP in patients undergoing pressure support ventilation and neurally adjusted ventilatory assist (NAVA) and ...
متن کاملAssessment of Factors Related to Auto-PEEP.
BACKGROUND Previous physiological studies have identified factors that are involved in auto-PEEP generation. In our study, we examined how much auto-PEEP is generated from factors that are involved in its development. METHODS One hundred eighty-six subjects undergoing controlled mechanical ventilation with persistent expiratory flow at the beginning of each inspiration were enrolled in the st...
متن کاملThe effect of pressure support ventilation on auto-PEEP in a patient with asthma.
We report the effect of pressure support ventilation (PSV) on auto-PEEP in a patient with asthma. The patient showed a high level of auto-PEEP during spontaneous breathing through a T-piece. PSV effectively decreased auto-PEEP and inspiratory muscle effort with increasing levels of PSV.
متن کاملIt's Time to Reappraise the Impact of Auto-PEEP.
Since Pepe and Marini1 first used the term auto-PEEP in 1982, many studies have been conducted in this field.2-5 For patients receiving mechanical ventilation, auto-PEEP is a common problem during the weaning process.2-4 Even in the acute stage of acute respiratory failure, patients may suffer from the detrimental effects of auto-PEEP.4,5 By definition, auto-PEEP occurs when air flow does not r...
متن کاملEffect of external PEEP in patients under controlled mechanical ventilation with an auto-PEEP of 5 cmH2O or higher
BACKGROUND In some patients with auto-positive end-expiratory pressure (auto-PEEP), application of PEEP lower than auto-PEEP maintains a constant total PEEP, therefore reducing the inspiratory threshold load without detrimental cardiovascular or respiratory effects. We refer to these patients as "complete PEEP-absorbers." Conversely, adverse effects of PEEP application could occur in patients w...
متن کاملAuto-positive end-expiratory pressure masquerading as loss of lung separation during thoracoscopy.
AUTO–positive end-expiratory pressure (auto-PEEP) is well described in patients with expiratory airflow obstruction, including those who require one-lung ventilation. Unfortunately, detecting auto-PEEP with most anesthesia ventilators is difficult. We report an unusual presentation of auto-PEEP during one-lung ventilation in which a reliable method of confirming lung separation quickly directed...
