Proportional assist versus pressure support ventilation in patients with acute respiratory failure: cardiorespiratory responses to artificially increased ventilatory demand.
OBJECTIVE To test the hypothesis that in response to increased ventilatory demand, dynamic inspiratory pressure assistance better compensates for increased workload compared with static pressure support ventilation (PSV). DESIGN Randomized clinical crossover study. SETTING General intensive care u nits of a university hospital. PATIENTS Twelve patients with acute respiratory failure. IN...
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...
متن کاملVentilation/perfusion mismatch caused by positive pressure ventilatory support.
In a patient with lobar atelectasis who was on positive pressure ventilatory support, ventilation and perfusion images showed absent ventilation and normal perfusion (reverse mismatch) in the region of the atelectasis and normal ventilation and decreased perfusion (true mismatch) not caused by pulmonary embolism in another lung zone. We report this case to emphasize that the lung scan findings ...
متن کاملAdaptive Support Ventilation as the sole mode of ventilatory support in chronically ventilated patients.
OBJECTIVE To describe the outcome of patients admitted to a new private facility for chronically ventilated patients in the Ashdod area of Israel. METHODS On arrival, all patients were placed on Adaptive Support Ventilation (ASV) at 90% of target minute ventilation for lean body weight, reducing progressively in weekly decrements of 10% down to 60% of target minute ventilation if adequate spo...
متن کاملwillingness to communicate in the iranian context: language learning orientation and social support
why some learners are willing to communicate in english, concurrently others are not, has been an intensive investigation in l2 education. willingness to communicate (wtc) proposed as initiating to communicate while given a choice has recently played a crucial role in l2 learning. it was hypothesized that wtc would be associated with language learning orientations (llos) as well as social suppo...
