  1. 1. Hyperbaric oxygen. Effects on ischemia-reperfusion

    Författare :Johan Tjärnström; Göteborgs universitet; []
    Nyckelord :fibrinolysis; f-MLP; human; hyperbaric oxygen; neutrophils; normobaric; PAI-1; PMA; rat; t-PA; trauma; uPA;

    Sammanfattning : Treatment with hyperbaric oxygen (HBO2) is controversial when treating other disorders than decompression sickness. However, HBO2 is a treatment modality that has gained recognition in certain ischemia-reperfusion situations. LÄS MER

  3. 2. Surviving under water : Physiological limitations and technical possibilities

    Författare :Mårten Silvanius; Oskar Frånberg; Rachel Lance; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diving; diving apparatus; unmanned testing; hyperbaric; scuba; oxygen sensor; composite gas cylinder; carbon dioxide monitoring; decompression; hyperbaric oxygen therapy; Systemteknik; Systems Engineering;

    Sammanfattning : The survival of humans in underwater environments necessitates a comprehensive understanding of both physiological factors and advanced technologies. Diving with self-contained underwater breathing apparatuses (SCUBA) remains one of the most common ways for human underwater activities. LÄS MER

  4. 3. Hyperbaric oxygen treatment for pelvic radiation-induced injuries. From a multicenter randomized controlled trial to an experimental cell model

    Författare :Nicklas Oscarsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hyperbaric oxygen treatment; hyperbaric oxygen; late radiation-induced injury; cystitis; proctitis; reactive oxygen species; radiation therapy; quality of life;

    Sammanfattning : Introduction Cancer is affecting a growing number of persons. Still, the treatment and survival of cancer is improving. Radiation therapy is used in the treatment of cancer. Late radiation-induced injuries afflict 5–15% of irradiated patients. LÄS MER

  5. 4. Oxygen content in semi-closed rebreathing apparatuses for underwater use : Measurements and modeling

    Författare :Oskar Frånberg; Ola Eiken; Mikael Gennser; Lars-Åke Brodin; John Clarke; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diving; rebreather; underwater breathing apparatus; unmanned testing; hyperbaric; metabolic simulator; scuba; semi-closed; Medicinsk teknologi; Medical Technology;

    Sammanfattning : The present series of unmanned hyperbaric tests were conducted in order to investigate the oxygen fraction variability in semi-closed underwater rebreathing apparatuses. The tested rebreathers were RB80 (Halcyon dive systems, High springs, FL, USA), IS-Mix (Interspiro AB, Stockholm, Sweden), CRABE (Aqua Lung, Carros Cedex, France), and Viper+ (Cobham plc, Davenport, IA, USA).

  7. 5. The safety relevance of standardized tests for diving equipment

    Författare :Mårten Silvanius; Oskar Frånberg; Greg Murphy; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diving; rebreather; underwater breathing apparatus; unmanned testing; hyperbaric; scuba; oxygen sensor; composite gas cylinder; carbon dioxide monitoring;

    Sammanfattning : Vital components are more or less prone to fail in a diving apparatus. This thesis examines the performance of oxygen sensors, carbon dioxide scrubber monitoring and composite gas cylinders. LÄS MER
