• breaths
  • Limiting tidal volume (V T ) in patients with ARDS may not be achieved once patient-triggered breaths occur. (rcjournal.com)
  • 6 mL/kg was significantly increased with spontaneous breaths patient-triggered by pressure support (OR 19.36, 95% CI 12.37-30.65) and significantly reduced in APRV (OR 0.44, 95% CI 0.26-0.72) and pressure support with guaranteed volume mode. (rcjournal.com)
  • 150 (Vf) breaths per minute) and very small tidal volumes. (wikipedia.org)
  • They work on a breath-by-breath basis and provide pressure-limited time-cycled breaths, increasing or decreasing the pressure of the next breath as necessary to achieve a user-selected desired tidal volume. (wikipedia.org)
  • lungs
  • The servo display is a general clinical indicator of changes in the compliance or resistance of the patient's lungs, as well as loss of lung volume due to tension pneumothorax. (wikipedia.org)
  • patient's
  • 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)
  • equation
  • 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)
  • versus
  • Calculated intrapulmonary shunt fraction was also similar with each tidal volume during OLV (5 ml.kg-1: 25±9% versus 10 ml.kg-1: 24±8%, p=0.14). (biomedsearch.com)
  • pressure
  • 6 mL/kg was significantly reduced in APRV and pressure support with guaranteed volume mode. (rcjournal.com)
  • Dual-control modes are pressure controlled modes with an exhaled tidal volume target. (wikipedia.org)
  • This pressure change will reduce the volume of a gas filled space by half. (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)
  • changes
  • A video of the dynamic changes in gas and blood volume during the respiratory cycle was obtained. (ersjournals.com)
  • The mean tidal volume values obtained with pneumotach and TIE4sys on the second group of COPD patients (M:4) were: 0.798±0.395 L and 0.732±0.327 L. The mean of the differences was 0.066±0.114L. The differences of determinations estimated with pneumotach and TIE4sys can be attributed to changes of anthropometric characteristics like subscapular skinfold. (upc.edu)
