  • Positive
  • There are a number of different ACT's such as the active cycle of breathing technique, high-frequency chest wall oscillations, positive expiratory pressure (PEP) and oscillatory PEP. (springer.com)
  • position
  • The digital information was used to compute automatically the volume of the trunk and the position of any point on its surface and its cross-sectional shape at any level. (wikipedia.org)
  • change
  • The technique used the distortion with movement of a structured pattern of light to calculate a volume or change in volume of a textured surface. (wikipedia.org)
  • pump
  • the heart has to work harder to pump the same volume of blood throughout the body, and for people with heart disease, this additional workload can cause the heart to go into arrest. (wikipedia.org)
  • magnitude
  • OBJECTIVE: This study aimed at assessing the evolution of cardiovascular characteristics during hemodialysis and ultrafiltration by a perturbation accurately defined in its magnitude and directly relevant to the problem of volume adjustment in stable hemodialysis patients. (biomedsearch.com)
  • flow
  • Spinal cord injury can be traumatic or nontraumatic, and can be classified into three types based on cause: mechanical forces, toxic, and ischemic (from lack of blood flow). (wikipedia.org)
  • However, during the expiratory phase, the expiratory flow can be commanded by an open-loop controller or a closed-loop controller: when the expiratory flow is open-loop controlled, it is fast initially and slowing down progressively after to minimize the risk of collapse generation. (wikipedia.org)
  • Also, during the inspiratory phase, the volume-controlled mode is realized by open-loop or closed loop control of the PFC flow. (wikipedia.org)
  • decrease
  • If the alveolus were to collapse, a great force would be required to open it, meaning that compliance would decrease drastically. (wikipedia.org)
  • fluid
  • METHODS: Excess fluid volume was removed by constant ultrafiltration-rate as prescribed. (biomedsearch.com)
  • The water in this fluid has a high surface tension, and provides a force that could collapse the alveolus. (wikipedia.org)
  • change
  • Barotraumas of ascent are also caused when the free change of volume of the gas in a closed space in contact with the diver is prevented. (wikipedia.org)
