• 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
• 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 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)
• 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)
• pressure
• 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)
• group
• One group is ventilated with a standard tidal volume of 10 ml/kg. (isrctn.com)
• Tidal Volume (TV) post-process obtained with electrical impedance tomography on a group of chronic obstructive pulmonary disease (COPD) patients. (upc.edu)
