BACKGROUND Pressure support ventilation from a bilevel device is a standard technique for non-invasive home ventilation. A bench study was designed to compare the performance and patient-ventilator synchronization of 7 bilevel ventilators, in the presence of system leaks. MATERIAL/METHODS Ventilators were connected to a Hans Rudolph Series 1101 lung(More)
Rapid detection of pathogens is of great significance for food safety and disease diagnosis. A new colorimetric method for rapid and easy detection of Vibrio parahaemolyticus (V. parahaemolyticus or Vp) has been developed in this research. A specific sequence was designed and integrated with the forward primer for molecular detection of Vp. This specific(More)
BACKGROUND Empirical three-step therapy has been proved in just one hospital. This study aimed to demonstrate applicability of the sequential empirical three-step therapy for chronic cough in different clinical settings. METHODS Sequential empirical three-step therapy was given to patients with chronic cough in one tertiary and three secondary care(More)
OBJECTIVE To compare the inspiratory cycling-off synchronization with different expiratory trigger sensitivity (ETS) setting during noninvasive pressure support ventilation (PSV) under the conditions of system leak. METHODS Ventilators were connected to a lung model (Hans Rudolph Series1101 simulator). And its mechanics was set in two models of(More)
BACKGROUND Pressure support ventilation (PSV) is a standard method for non-invasive home ventilation. A bench study was designed to compare the effectiveness of patient-ventilator inspiratory termination synchronization with automated and conventional triggering in various respiratory mechanics models. MATERIAL AND METHODS Two ventilators, the Respironics(More)
