  2. 1. Regulation of Breathing under Different Pulmonary Conditions

    Author : Esther Rieger-Fackeldey; Gunnar Sedin; Anders Jonzon; Richard Sindelar; Andreas Schulze; Richard Martin; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatrics; Control of breathing; Pulmonary Stretch Receptor; Phrenic Nerve Activity; Respiratory Distress Syndrome; Surfactant; Partial Liquid Ventilation; Assisted Ventilation; Pediatrik; Paediatric medicine; Pediatrisk medicin;

    Abstract : The breathing pattern of preterm infants is immature and is associated with a variety of reflexes. In a patient on the ventilator these reflexes interfere with spontaneous breathing. A better understanding of the immature control of breathing could lead to further improvements in ventilatory techniques. READ MORE

  4. 2. Breathing Pattern and Lung Mechanics during Assisted Ventilation Response of Slowly Adapting Pulmonary Stretch Receptors and Effects on Phrenic Nerve Activity in Cats with Normal and Surfactant Depleted Lungs

    Author : Richard Sindelar; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstetrics and gynaecology; slowly adapting pulmonary stretch receptor; phrenic nerve activity; assisted ventilation; surfactant; breathing pattern; Obstetrik och kvinnosjukdomar; Obstetrics and women s diseases; Obstetrik och kvinnosjukdomar; pediatrik; Pediatrics;

    Abstract : Different modes of assisted ventilation were investigated in cats before and after lung lavage and after instillation of surfactant. The activity of single units of slowly adapting pulmonary stretch receptors (PSRs) in the vagal nerve and the integrated phrenic nerve activity were recorded. READ MORE

  5. 3. Inactivation of pulmonary surfactant and its prevention

    Author : Guido Stichtenoth; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Pulmonary surfactant is a lipoprotein complex coating the conducting airways down to the terminal airspaces. Its main function is to lower surface tension at the air liquid interface thus preventing alveolar collapse at end expiration. READ MORE

  6. 4. A Surface Phase Model of the Alveolar Lining: Ultrastructural Analysis and in vivo Applications

    Author : Marcus Larsson; Lund Pediatrik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; X-ray diffraction; cryo-TEM; dynamic swelling; ARDS; surface phase; surfactant replacement therapy; cholesterol; minimal surface; pulmonary surfactant; alveolar surface; Physiology; Fysiologi;

    Abstract : In this thesis the relation between lung surfactant structure and functional properties have been studied. Experimental results show that the alveolar surface is formed by a coherent surface phase with a structure equal to tubular myelin. The properties of this phase may explain certain unresolved issues in lung physiology, e.g. READ MORE

  7. 5. Synthetic pulmonary surfactant : effects of surfactant proteins B and C and their analogues

    Author : Andreas Almlén; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Pulmonary surfactant is a lipid/protein mixture lining the air-liquid interface in the alveoli. Its main function is to lower surface tension during respiration and thereby prevent alveolar collapse at end-expiration. Surfactant deficiency, especially common in prematurely born babies, is the main cause of respiratory distress syndrome (RDS). READ MORE
