Ventilator-associated pneumonia (VAP) is a common and serious complication of mechanical ventilation via an artificial airway. As with all nosocomial infections, VAP increases costs, morbidity, and mortality in the intensive care unit (ICU). VAP prevention is a multifaceted priority of the intensive care team, and can include the use of specialized artificial airways and heat-and-moisture excha...

background: oral care plays an inevitable role in health and well-being of patients in intensive care units (icus). poor oral care causes colonization of respiratory pathogens and secondary respiratory infections. ventilator-associated pneumonia occurs in patients on mechanical ventilation for more than 48 hours. it results in prolonged duration of mechanical ventilation, mortality and health e...

Though artificial ventilation is an essential life-saving treatment, the mechanical behavior of lung tissue at the alveolar level is still unknown. Therefore, we need to understand the tissue response during artificial ventilation at this microscale in order to develop new and more protective ventilation methods. Optical coherence tomography (OCT) combined with intravital microscopy (IVM) is a ...

a bstract background: mechanical ventilation is one of the supporting treatments that are used for different reasons. to reduce patients’ inconvenience caused due to using tracheal tube and ventilator, sedation is routinely used. using scales for the sedation, for example, richmond agitation sedation scale (rass), may reduce dose of sedation and length of mechanical ventilation.   materials and...

Several factors interact in influencing aerosol deposition during mechanical ventilation. Among these factors, the artificial airway is a significant barrier for aerosol deposition. Earlier studies overemphasized the impediments created by the artificial airway to aerosol delivery, because the aerosol generator was placed adjacent to the endotracheal tube or was connected to it. When the aeroso...

There have been a number of studies of the physiological effects of different tracheal pressure wave patterns in patients requiring artificial ventilation with intermittent positive pressure (IPPV) (Werko, 1947; Cournand et al., 1948; Maloney et al., 1953; Watson, 1962a, b; Bergman, 1963, 1967; Grenvik, 1966; Auchinloss and Gilbert, 1967; Robinson, 1967; Herzog and Norlander, 1968; Adams et al....

A study has been performed to measure the resistance of Pall Ultipor BB50 filters when exposed to humidified air for 48 h during artificial ventilation by an Engstrom Erica ventilator fitted with a Bennett Cascade Mk2 humidifier. A marked increase in resistance was demonstrated. A hypothesis is presented as to the aetiology of these findings together with details of minor modifications to the s...
