  1. 11. The preterm infant : evaluating and developing non-invasive respiratory strategies to avoid mechanical ventilation

    Författare :Snorri F Donaldsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Avoiding mechanical ventilation of preterm infants is important to prevent morbidity and mortality. Non-invasive ventilation and CPAP has been shown to be superior to intubation and mechanical ventilation in preventing chronic lung disease in very preterm infants.1 . CPAP for infants was first used in the early 70’s. LÄS MER

  2. 12. Outcomes and Implications of Nasal Measurements in Obstructive Sleep Apnea

    Författare :Hans Christian Hoel; Lund näs- och halssjukdomar Öron-; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstructive sleep apnea OSA ; Respiratory system diagnostic technique; nasal obstruction; Sleep hypopnea; Rhinomanometry;

    Sammanfattning : BackgroundObstructive sleep apnea (OSA) is a prevalent disorder and symptoms of nasal obstruction are highly prevalent in OSA. Treatment of nasal obstruction in OSA patients has shown modest and variable outcomes in reducing the apnea hypopnea index (AHI), but significant improvements in other indicators, such as sleep quality and daytime sleepiness as well as reductions in arousals have been observed.

  3. 13. Performance of NCPAP systems for neonatal use and development of a new system for infant resuscitation

    Författare :Thomas Drevhammar; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Objective: Nasal continuous positive airway pressure (NCPAP) is the most commonly used respiratory support for newborn infants. It is a technique for non-invasive respiratory support of both term and preterm infants with respiratory distress. LÄS MER

  4. 14. Unresolved Controversies in Child Pneumonia in low and middle income Countries

    Författare :Nick Brown; Andreas Mårtensson; Mats Målqvist; Stephen Allen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Paediatrics; pneumonia; global health; antibiotics; poverty; risk scoring; Pediatrik; Pediatrics; Epidemiologi; Epidemiology;

    Sammanfattning : There has been a fall globally in pneumonia-related fatality in children during the Millennium Development and early Sustainable Development Goal era.However, pneumonia remains the single largest contributor to mortality with issues including antibiotic resistance, pollution, a change in infective epidemiology, equipoise over effects of adjunctive treatments and identification of sick, decompensating children.

  5. 15. Studies of diaphragm fatigue and dysfunction

    Författare :Peter J Radell; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Diaphragm function; contractility; fatigue; oxidative metabolism; 31phosphorus nuclear magnetic spectroscopy; ultrasonography; prolonged ventilation; compound muscle action potential; myopathy; electroneurography; muscle fiber; morphology.;

    Sammanfattning : Diaphragm fatigue and dysfunction are important components of acute and chronic respiratory pump failure. We lack knowledge about the nature of diaphragm fatigue and the pathophysiological and morphological changes that occur in the diaphragm after prolonged mechanical ventilation. This thesis studied two aspects of diaphragm function. LÄS MER
