Albuterol delivery via intrapulmonary percussive ventilator and jet nebulizer in a pediatric ventilator model.
BACKGROUND In-line administration of bronchodilators is widely used in pediatric patients receiving mechanical ventilation. We compared the amount of albuterol captured at the end of the endotracheal tube (ETT) with an intrapulmonary percussive ventilator (IPV) versus a Salter 8900 jet nebulizer placed in-line in a pediatric ventilator model, under various operating conditions. We hypothesized ...
متن کاملCellular stress failure in ventilator-injured lungs.
The clinical and experimental literature has unequivocally established that mechanical ventilation with large tidal volumes is injurious to the lung. However, uncertainty about the micromechanics of injured lungs and the numerous degrees of freedom in ventilator settings leave many unanswered questions about the biophysical determinants of lung injury. In this review we focus on experimental ev...
متن کامل[Interpretation of ventilator curves in patients with acute respiratory failure].
Mechanical ventilation is a therapeutic intervention involving the temporary replacement of ventilatory function with the purpose of improving symptoms in patients with acute respiratory failure. Technological advances have facilitated the development of sophisticated ventilators for viewing and recording the respiratory waveforms, which are a valuable source of information for the clinician. T...
متن کاملJet or intensive care unit ventilator during simulated percutaneous transtracheal ventilation: a lung model study.
BACKGROUND Percutaneous transtracheal ventilation (PTV) via a jet ventilator (PTJV) is considered a rescue technique in difficult airway management. However, whether a conventional ventilator can generate adequate ventilation via PTV is not known. Our goal was to evaluate the tidal volume (V(T)) generated by a conventional ventilator during simulated PTV compared with PTJV in a lung model. ME...
متن کاملVentilator-integrated jet nebulization systems: tidal volume control and efficiency of synchronization.
BACKGROUND Jet nebulizers constitute the aerosolization devices most frequently used during mechanical ventilation. Continuous nebulization can influence the delivered tidal volume (V(T)) and lead to significant medication loss during expiration. Ventilators thus provide integrated jet nebulization systems that are synchronized during inspiration and ostensibly keep VT constant. METHODS This ...
