  2. 1. Intraocular pressure : clinical aspects and new measurement methods

    Author : Gauti Jóhannesson; Christina Lindén; Per Hallberg; Anders Eklund; Boel Bengtsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intraocular pressure; glaucoma; tonometry; ISO; LASEK; CCT; curvature; Ophtalmiatrics; Oftalmiatrik; Ophtalmology; oftalmiatrik;

    Abstract : Intraocular pressure (IOP) measurement is a routine procedure and a fundament in glaucoma care. Elevated IOP is the main risk factor for glaucoma, and to date, reduction of IOP is the only possible treatment. In a retrospective clinical material, the prevalence of open angle glaucoma was estimated on the west coast of Iceland. READ MORE

  4. 2. Pressure sores : risk assessment and prevention

    Author : Margareta Lindgren; Christina Lindholm; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : The aims of this thesis were to study the prevalence, incidence, prevention and treatment of pressure sores, to further develop a risk assessment scale, and test the reliability and validity of this scale, to identify risk factors for pressure sore development, and to study skin blood flow in non-blanchable erythema areas as compared to undamaged skin.Criteria used for pressure sore assessment were persistent discoloration i.

  5. 3. Transpulmonary pressure during mechanical ventilation

    Author : Christina Grivans; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mechanical ventilation; Acute lung injury; Acute respiratory distress syndrome; Lung volume measurements; Electric Impedance diagnostic use; Lung elastance; Transpulmonary pressure; Esophageal pressure;

    Abstract : Background: Mechanical ventilation can aggravate lung injury by repetitive opening and closing of lung units, overdistention and undue pressure on pulmonary structures. Guidelines exist for lung protective ventilation, but individualized ventilator settings, based on partitioning of respiratory mechanics in pulmonary and chest wall complex components, would be beneficial.

  6. 4. Middle Ear Pressure; A New Method for Continuous Direct Measurements

    Author : Bo Tideholm; allergi och livskvalitet Laryngoesofagologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Otorhinolaryngology; man; physiology; sleep; posture; pressure; patulous Eustachian tube; middle ear; Ear; audiology; auditive system and speech; Otorinolaryngologi; audiologi; hörsel- och talorganen;

    Abstract : Disturbances in the pressure homeostasis of the middle ear (ME) system cause a pressure gradient across the tympanic membrane lessen the effectiveness of sound transmission and may be associated to development of chronic ME disease. An equipment for continuous direct pressure measurements was developed and was found to be accurate, base-line stabile and portable. READ MORE

  7. 5. Pressure Ulcer Prevention : Performance and Implementation in Hospital Settings

    Author : Eva Sving; Lena Gunningberg; Marieann Högman; Anna-greta Mamhidir; Helle Wijk; Uppsala universitet; []
