  1. 1. Lung volumes and lung mechanics in anesthetized children

    Author : Adalbjörn Thorsteinsson; Anestesiologi och intensivvård; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sulfur hexafluoride; Anaesthesiology; lung volumes; lung compliance; Anesthesia: pediatric; functional residual capacity; intensive care; Anestesiologi; ventilation inhomogeneity; intensivvård; airway closure;

    Abstract : The thesis was intended to fill gaps in the knowledge regarding the normal development of lung volumes and lung mechanics in children, from young infancy to the mid-teens. In particular, data were previously lacking regarding pre-school children. The studies were done during anesthesia and muscle relaxation. READ MORE

  2. 2. 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.

  3. 3. Open and closed endotracheal suctioning. Experimental and human studies

    Author : Sophie Lindgren; Göteborgs universitet; []
    Keywords : suctioning; endotracheal; closed system suctioning; monitoring; lung volume; airway pressure; lung recruitment; bronchoalveolar lavage; acute lung injury;

    Abstract : Background: The practice of endotracheal suctioning of ventilator treated patients is necessary to remove secretions to prevent obstruction of the endotracheal-tracheal tube and lower airways. This very common procedure creates a large variety of heart-lung interferences. READ MORE

  4. 4. Cross-modal Imaging in Lung Research: From µCT dosimetry to synchrotron phase contrast microtomography biomechanical insights in preclinical lung injury models

    Author : Richard Deyhle Jr; Malmö Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Thermoluminescent Dosimetry; Optically stimulated luminescence OSL ; Computed tomography CT ; 4DCT; Phantoms; Imaging; X-rays; pre-clinical models; Pre-clinical; dosimetry: physical basis; biomedical strain; lung injury; mechanical ventilation; inflammation; lung function; synchrotron; histology; acute respiratory distress syndrome ARDS ; Ventilator Inudced Lung Injury VILI ; Histology; Forced Oscillation Technique FOT ; Divergence Theorem; Registration techniques;

    Abstract : Lung diseases continue to present a large burden to public health, especially in industrialized countries. For abetter understanding of the underlying patho-mechanisms in lung related diseases as well as for testing theefficacy of novel therapies, preclinical studies in animal models are indispensable.

  5. 5. Fractional moving blood volume in fetal organs estimated using power Doppler ultrasound

    Author : Edgar Hernandez-Andrade; Lund Obstetrik och gynekologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reproduction; andrology; gynaecology; Obstetrics; sexuality; Obstetrik; gynekologi; andrologi; reproduktion; sexualitet; fetal adrenal gland; fetal lung; radionuclear microspheres; fetal lamb; perfusion; fetus; Power Doppler ultrasound; fractional moving blood volume;

    Abstract : Power Doppler ultrasound (PDU) is a sensitive technique to detect slow blood movement. The aim of the present study was to develop a standardized method for quantification of the PDU signals recorded from a specific region of interest (ROI) within fetal organs. READ MORE
