The effect of pressure support ventilation on auto-PEEP in a patient with asthma.

چکیده
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.

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 کاملMeasurement of air trapping, intrinsic positive end-expiratory pressure, and dynamic hyperinflation in mechanically ventilated patients.
Severe airflow obstruction is a common cause of acute respiratory failure. Dynamic hyperinflation affects tidal ventilation, increases airways resistance, and causes intrinsic positive end-expiratory pressure (auto-PEEP). Most patients with asthma and chronic obstructive pulmonary disease have dynamic hyperinflation and auto-PEEP during mechanical ventilation, which can cause hemodynamic compro...

Background and Objective: Some of multiple trauma patients admitted in ICU (Intensive Care Unit) are intubated and ventilated by mechanical ventilation. These patients are prone to many complications such as lung disease. Reasons for this complication are patients without any movement, incomplete cough reflex, GI aspiration and then not a good pulmonary discharge prone the lungs of patients to ...
متن کاملComparison of the effect of pressure support ventilation and volume assured pressure support ventilation on weaning patients off mechanical ventilation after cardiac surgery
Background: Weaning from mechanical ventilation in the intensive care unit is an important step in the treatment process. More patients in less than 6 hours after cardiac surgery can be separated from mechanical ventilation and extubated. However, 20-40% of patients after cardiac surgery, due to dysfunctional ventilator weaning response (DVWR), still remain under mechanical ventilation. Therefo...
