  1. 6. 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).

  3. 7. 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

  4. 8. Infections and hyperbaric oxygen : new methods for highdose protocols and noninvasive measurements

    Författare :Agneta C Larsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The scientific evidence of Hyperbaric Oxygen Treatment is despite the fact that the hyperbaric method has been in use since 1662 still under debate. At Karolinska University Hospital the method has been under the supervision of the department of anesthesia and intensive care since 1990. LÄS MER

    Sammanfattning : Objective: Cervical cancer stands for the predominant cause of cancer death among Rwandan women. Chronic Human Papillomavirus (HPV) infection constitutes the main risk factor. LÄS MER

  7. 10. On implant integration in irradiated bone : clinical and experimental studies

    Författare :Jan Nyberg; Börje Svensson; Christer Dahlin; Carina B. Johansson; Bo Sunzel; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dental implant; osseointegration; radiation therapy; bone remodeling; histomorphometry; hyperbaric oxygen therapy; gene expression and in vivo; Surgery; Kirurgi;

    Sammanfattning : Radiation has an impact on the processes involved in bone- healing, regeneration and remodeling. The mechanisms that cause impaired bone healing of dental implants are not fully understood. Adjunctive treatments to revers radiation effects are limited. LÄS MER
