  2. 1. Titrating Open Lung PEEP in Acute Lung Injury : A clinical method based on changes in dynamic compliance

    Author : Fernando Suarez Sipmann; Göran Hedenstierna; Hans Hedenström; Stefan Lundin; Uppsala universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; PEEP; open lung; recruitment; dead space; electrical impedance tomography; ARDS.; Medicine; Medicin;

    Abstract : The recognition that supportive mechanical ventilation can also damage the lung, the so called ventilation induced lung injury (VILI), has revived the more than 40 year long debate on the optimal level of PEEP to be used. It is established that the prevention of VILI improves patient outcome and that PEEP exerts protective effects by preventing unstable diseased alveoli from collapsing. READ MORE

  4. 2. Tools for protective lung ventilation. The elastic pressure-volume curve and aspiration of dead space

    Author : Edoardo De Robertis; Lund Klinisk fysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical physics; radiology; tomografi; medicinsk instrumentering; radiologi; Klinisk fysiologi; tomography; medical instrumentation; Respiratory system; Andningsorganen;

    Abstract : Ventilator-induced lung injury (VILI) may contribute to morbidity and mortality of acute lung injury (ALI). Lung protective ventilation (LPV), that reduces VILI, may involve low tidal volume (Vt). Particularly low Vt is possible if dead space ventilation is reduced e.g. READ MORE

  5. 3. Computer simulation - a tool for optimisation of ventilator setting in critical lung disease

    Author : Leif Uttman; Lund Klinisk fysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adult · Swine; Computer Simulation ·Artificial Respiration ·Pulmonary Gas Exchange · Respiratory Dead Space · Respiratory Mechanics · Respiratory Distress Syndrome; Physiology; Fysiologi;

    Abstract : Increasing attention is paid to mechanical ventilation as one cause behind aggravation of lung injury. Lung protective ventilation can be achieved e.g. by minimising tidal lung collapse and re-expansion and by the use of small tidal volume allowing some degree of permissive hypercapnia. READ MORE

  6. 4. Pulmonary ventilation and perfusion assessed by electrical impedance tomography - Experimental studies in pigs

    Author : Anneli Fagerberg; Göteborgs universitet; []
    Keywords : electrical impedance tomography; V Q matching; pig; endotoxinaemic ALI; ACE inhibitor;

    Abstract : Pulmonary ventilation and perfusion and ventilation/perfusion (V/Q) matching determine gas exchange in every lung unit in the healthy state and in the pathologically altered lung. Mismatch of V and Q lead to hypoxaemia and hypercapnia and monitoring of V/Q relations are thus important in critical illness. READ MORE

  7. 5. Soil salinity as a driver of microbial community structure and functioning

    Author : Kristin Rath; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Soil salinization; Soil Microbiology; soil microbial community; Bacteria; Aerobic; Fungi; Drying-rewetting; Microbial growth; Microbial biomass; Soil respiration; salinity tolerance; Saline soils; Salinity gradient;

    Abstract : Soil salinization is a pressing agricultural problem in many areas of the world, particularly in areas heavily reliant on irrigation agriculture. While the negative effects of salinity on crop plants have been widely studied, its effects on soil microorganisms have received less attention, and the impact of soil salinity on both microbial community structure and functioning is not well understood.
