  2. 1. Pressure Ulcer Prevention : Performance and Implementation in Hospital Settings

    Author : Eva Sving; Lena Gunningberg; Marieann Högman; Anna-greta Mamhidir; Helle Wijk; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pressure ulcer prevention; nursing care; implementation; Trycksårsprevention; omvårdnad; implementering; Omvårdnadsforskning med samhällsvetenskaplig inriktning; Caring Sciences in Social Sciences;

    Abstract : Background: Pressure ulcers are related to reduced quality of life for patients and high costs for health care. Guidelines for pressure ulcer prevention have been available for many years but the problem remains. READ MORE

  4. 2. Analysis of ICP pulsatility and CSF dynamics : the pulsatility curve and effects of postural changes, with implications for idiopathic normal pressure hydrocephalus

    Author : Sara Qvarlander; Anders Eklund; Jan Malm; Richard Birgander; Martin U Schuhmann; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cerebrospinal fluid; CSF dynamics; Intracranial pressure; Pulse pressure; Normal pressure hydrocephalus; Posture; Predictive tests; Mathematical modelling; Magnetic resonance imaging; Infusion tests;

    Abstract : The volume defined by the rigid cranium is shared by the brain, blood and cerebrospinal fluid (CSF). With every heartbeat the arterial blood volume briefly increases and venous blood and CSF are forced out of the cranium, leading to pulsatility in CSF flow and intracranial pressure (ICP). READ MORE

  6. 4. Collision Threshold Pressure : A novel measure of voice function Effects of vocal warm-up, vocal loading and resonance tube phonation in water

    Author : Laura Enflo; Anita McAllister; Johan Sundberg; Marc de Bodt; Linköpings universitet; []
    Keywords : ;

    Abstract : The phonation threshold pressure (PTP), i.e., the smallest amount of subglottal pressure needed to initiate and sustain vocal fold oscillation, is frequently difficult to measure due to the difficulty for some subjects to produce extremely soft phonation. In addition, PTP values are often quite scattered. READ MORE

  7. 5. Effects of anasthesia on esophageal sphincters

    Author : Rebecca Ahlstrand; Magnus Wattvil; Johan Ullman; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lower esophageal shincter; Upper esophageal sphincter; Barrier pressure; Manometry; Propofol; Remifentanil; Alfentanil; Rocuronium; Cricoid pressure; MEDICINE; MEDICIN; Surgery; Kirurgi; Anaesthetics; Anestesiologi; Anaesthesiology; Anestesiologi;

    Abstract : The esophageal sphincters constitute the anatomical protection against pulmonary aspiration. The aim of this thesis was to study the esophageal sphincters and how they are affected by different components of emergency anesthesia using high-resolution solid-state manometry.The effect of propofol (0.
