1. 1. 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.

3. 2. Effects of Deep Breathing Exercises after Coronary Artery Bypass Surgery

   Författare :Elisabeth Westerdahl; Arne Tenling; Göran Hedenstierna; Birgitta Lindmark; Anders Larsson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physical therapy; atelectasis; breathing exercises; coronary artery bypass; computed tomography; physiotherapy; postoperative care; postoperative complications; respiratory function tests; thoracic surgery; Sjukgymnastik; Physiotherapy; Sjukgymnastik fysioterapi;

   Sammanfattning : Deep breathing exercises are widely used in the postoperative care to prevent or reduce pulmonary complications, but no scientific evidence for the efficacy has been found after coronary artery bypass grafting (CABG) surgery. The aim of the thesis was to describe postoperative pulmonary function and to evaluate the efficacy of deep breathing exercises performed with or without a blow bottle device for positive expiratory pressure (PEP) 10 cmH2O or an inspiratory resistance-positive expiratory pressure (IR-PEP) mask with an inspiratory pressure of -5 cmH2O and an expiratory pressure of +10 to +15 cmH2O.

4. 3. 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

5. 4. The breathing brainstem : development of inspiration

   Författare :David Forsberg; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Breathing is essential for life, and yet we do not fully understand the mechanisms that control it. The main central pattern generators for respiration include the inspiratory generating region called the preBötzinger Complex (preBötC), and the chemosensitive region called the parafacial respiratory group/retrotrapezoid nucleus (pFRG/RTN).

7. 5. On the Formation and Physical Behaviour of Exhaled Particles

   Författare :Helene Holmgren; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; breath hold; size distribution; deposition; relative humidity; tidal breathing; exhaled particles; airway closure; film droplet;

   Sammanfattning : Aerosol particles are generated in human airways and leave the body with exhaled air. The particles originate from the respiratory tract and contain non-volatile compoundsthat potentially may be used as biomarkers for various medical conditions. To utilise any information provided by the particles, they must be characterised. LÄS MER
