HIgh frequency oscilatory ventilation in adults - Research Paper Example From that time individuals have learnt that as much as mechanical ventilation is always lifesaving also it can be injurious, particularly in patients who suffer from ARDS (acute respiratory distress syndrome). ARDS may also lead to refractory hypoxemia that can always trigger attempting ventilation strategies that are nonconventional like use of prone positioning, nitric oxide or recruitment maneuvers. HFOV (high frequency oscillatory ventilation) has emerged to be a rescue strategy for ARDS adults. To add to that, as it injures the lung is no more than ventilation conventional modes it can also be preferably suited to apply early in acute respiratory distress syndrome. High frequency oscillatory ventilation fits in the range of high frequency modes of ventilation whose main concept is breaths delivery at low volumes of tides and high frequency modes of ventilation which are always beneath the anatomy dead space. The high frequency mode is generally divided into the ones in which expiratory stage is passive and the ones in which there is an active expiration. Examples of tools using passive expiration are positive pressure ventilation and jet ventilation of high frequency (Miller, pp.1446) During HFOV high airway and very minute volumes pressure are used to prevent injuries form over distention and repetition reopening and collapse of the atelectrauma (lung). This allows for optimization of exchange of gas and possibly reduces iatrogenic damage. Oscillate trial is a varied Centre RCT where the mature individuals with severe ARDS were indiscriminately attached to HFOV or to convectional strategy: high pressures were used for both groups to keep lung recruitment at its maximum. The basic result was the in hospital death rate from any source. The oscillatory was brought to a stop after five hundred and forty eight out of the planned one thousand two hundred patients had passed through randomization as the application of HFOV
