Short-Term Effects of Positive Expiratory Airway Pressure in Patients Being Weaned from Mechanical Ventilation
OBJECTIVE To investigate the feasibility and the cardiorespiratory effects of using positive expiratory airway pressure, a physiotherapeutic tool, in comparison with a T-tube, to wean patients from mechanical ventilation. METHODS/DESIGN A prospective, randomized, cross-over study. SETTING Two intensive care units. PATIENTS AND INTERVENTIONS We evaluated forty patients who met weaning crit...
متن کاملBilevel Positive Airway Pressure Ventilation
Over the past few decades, invasive positive pressure ventilation, usually applied via an endotracheal tube, has been the standard treatment for acute respiratory failure [1–3]. However, intubation and mechanical ventilation is associated with significant morbidity, including upper airway trauma and infections [4–7]; indeed, it is the single most important predisposing factor for nosocomial pne...
متن کاملEffects of positive end-expiratory pressure ventilation on cerebral venous pressure with head elevation in dogs.
Mechanical ventilation with positive end-expiratory pressure (PEEP) may prevent venous air embolism in the sitting position because cerebral venous pressure (Pcev) could be increased by the PEEP-induced increase in right atrial pressure (Pra). Whereas it is clear that there is a linear transmission of the PEEP-induced increase in Pra to Pcev while the dog is in the prone position, the mechanism...
متن کاملParadoxical responses to positive end-expiratory pressure in patients with airway obstruction during controlled ventilation.
OBJECTIVE To reevaluate the clinical impact of external positive end-expiratory pressure (external-PEEP) application in patients with severe airway obstruction during controlled mechanical ventilation. The controversial occurrence of a paradoxic lung deflation promoted by PEEP was scrutinized. DESIGN External-PEEP was applied stepwise (2 cm H(2)O, 5-min steps) from zero-PEEP to 150% of intrin...
متن کاملSetting positive end-expiratory pressure during jet ventilation to replicate the mean airway pressure of oscillatory ventilation.
BACKGROUND High-frequency ventilation can be delivered with either oscillatory ventilation (HFOV) or jet ventilation (HFJV). Traditional clinician biases may limit the range of function of these important ventilation modes. We hypothesized that (1) the jet ventilator can be an accurate monitor of mean airway pressure (P (aw)) during HFOV, and (2) a mathematical relationship can be used to deter...
