  • When treating atelectasis, IPPB is only useful in the treatment of atelectasis if the volume delivered exceeds those volumes achieved by the patient's spontaneous efforts. (wikipedia.org)
  • conventional
  • The control strategy included target tidal volumes of 6 mL/kg of predicted body weight, plateau airway pressures not exceeding 30 cm H2O, and conventional levels of positive end-expiratory pressure (n = 508). (nih.gov)
  • equation
  • In this study, an equation based on sex and height was used to calculate a predicted body weight, which was then used to set tidal volumes. (bmj.com)
  • A ventilator assists breathing using either pressure control or volume control based on the equation of motion for the respiratory system. (wikipedia.org)
  • A simple mathematical model describing this fact is known as the equation of motion for the passive respiratory system: Pressure = (Elastance × Volume) + (Resistance × Flow) In this equation, pressure, volume, and flow are all continuous functions of time. (wikipedia.org)
  • In other words, the left-hand side of the equation of motion remains constant while volume and flow change with changes in elastance and resistance. (wikipedia.org)
  • pressure
  • The ventilator will attempt to deliver the set tidal volume utilizing whatever pressure is required to reach its setting. (wikipedia.org)
  • Boyle's law describes the relationship between the volume of the gas space and the pressure in the gas. (wikipedia.org)
  • Barotraumas of descent are caused by preventing the free change of volume of the gas in a closed space in contact with the diver, resulting in a pressure difference between the tissues and the gas space, and the unbalanced force due to this pressure difference causes deformation of the tissues resulting in cell rupture. (wikipedia.org)
  • Providing assistance means doing work on the patient, which is accomplished by controlling either pressure or volume. (wikipedia.org)
  • Time control (TC) means that, in some rare situations, none of the main variables (pressure, volume, or flow) are preset. (wikipedia.org)
  • approach
  • 1 It differs from 3 previous negative trials 2 - 4 by having a larger difference in tidal volumes between groups, and by having a more aggressive approach to correcting acidosis. (bmj.com)
