1. 6. Sleep disordered breathing : Natural evolution and metabolism

   Författare :Ahmed Elmasry; Uppsala universitet; []
   Nyckelord :Medical sciences; snoring; sleep apnea; epidemiology; obesity; diabetes; catecholamines; hypertension; evolution; population-based; prospective; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

   Sammanfattning : Sleep disordered breathing is manifested by snoring and repeated episodes of apneas and hypopneas. The induced hypoxia and sleep fragmentation are thought to be responsible for many metabolic disturbances.In 1984, 3,201 men aged 30 to 69 answered a questionnaire on snoring, sleep disorders and somatic diseases. In 1994, 2,668 of the survivors (89. LÄS MER

3. 7. Lung Function, Respiratory Muscle Strength and Effects of Breathing Exercises in Cardiac Surgery Patients

   Författare :Charlotte Urell; Margareta Emtner; Elisabeth Westerdahl; Hans Hedenström; Agneta Ståhle; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Breathing exercises; Cardiac surgery; Deep breathing; Lung function; Oxygenation; Physical therapy; Positive expiratory pressure; Spirometry; Respiratory muscle strength; Medicinsk vetenskap; Medical Science;

   Sammanfattning : Background: Breathing exercises are widely used after cardiac surgery. The duration of exercises in the immediate postoperative period is not fully evaluated and only limited data regarding the effects of home-based breathing exercises after discharge from hospital have been published.

4. 8. Resistance breathing with PEP and CPAP : effects on respiratory parameters

   Författare :Maria Sehlin; Ola Winsö; Karin Wadell; Fredrik Öhberg; Monika Fagevik Olsèn; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chest physiotherapy; breathing exercises; PEP; CPAP; airway pressure; airflow; threshold resistor; flow resistor; inspiratory capacity; Borg CR10;

   Sammanfattning : Background: Positive expiratory pressure (PEP) and continuous positive airway pressure (CPAP) are two forms of resistance breathing used in spontaneously breathing patients. With a threshold resistor or a flow resistor, both PEP and CPAP provide a positive (elevated) pressure level during the expiratory phase. LÄS MER

5. 9. Dosimetric effects of breathing motion in radiotherapy

   Författare :Anneli Edvardsson; Lund Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; radiotherapy; breathing motion; DIBH; interplay effects; VMAT; proton therapy; breast cancer; Hodgkin’s lymphoma; liver; dosimetry; treatment planning; medical physics;

   Sammanfattning : The goal of radiotherapy is to deliver a homogeneous high dose of radiation to a tumour while minimising the dose to the surrounding healthy tissue. To achieve this, increasingly advanced treatment techniques, such as volumetric modulated arc therapy (VMAT) and proton therapy, have been developed. LÄS MER

7. 10. Regulation of Breathing under Different Pulmonary Conditions

   Författare :Esther Rieger-Fackeldey; Gunnar Sedin; Anders Jonzon; Richard Sindelar; Andreas Schulze; Richard Martin; Uppsala universitet; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER
