2. 1. Respiratory inductive plethysmography (RIP) : calibration, breathing pattern analysis and external CO2 dead space measurement

   Author : Tomas Strömberg; Gert Nilsson; Per M. Gustafsson; Steffen Groth; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : Respiratory inductive plethysmography (RIP) is an important tool for ventilatory monitoring in research studies because it has minimal influence on the spontaneous breathing pattern and because the rib cage and abdominal contributions to the breaths are measured. RIP measures changes in rib cage and abdominal cross-sectional areas which are translated into lung volume estimates via RIP calibration against e. READ MORE

4. 2. Lung function after cardiac surgery : With special reference to atelectasis and ventilation-perfusion relationships

   Author : Arne Tenling; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Cardiac surgery; thoracic epidural analgesia; vital capacity manoeuvre; computed tomography; ventilation-perfusion relationships; gas exchange; atelectasis; respiratory inductive plethysmography; Kirurgi; Surgery; Kirurgi; anestesiologi; Anaesthesiology;

   Abstract : Patients undergoing cardiac surgery were investigated before and after the operation.Ventilation-perfusion (VA/Q) relationships were examined by the multiple inert gas elimination method, and atelectasis and aeration of the lungs were examined by computedtomography (CT). READ MORE

5. 3. Breating pattern by inductive plethysmography in relatidon to bronchial obstruction in asthma

   Author : Tomas Strömberg; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : This work aimed at improving a method for "non-invasive" ventilatory monitoring (the respiratory inductive plethysmography; RIP), and at assessing whether RIP can be used for detection and monitoring of bronchial obstruction in asthma.The RIP measures the changes in rib cage and abdominal cross-sectional areas during breathing.

6. 4. New modes of improving ventilation and oxygenation in pulmonary hypertension and acute respiratory failure in newborns and children

   Author : Sylvia Göthberg; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Inhaled nitric oxide; high frequency oscillatory ventilation; partial liquid ventilation; respiratory inductive plethysmography; follow-up study; pulmonary hypertension; congenital heart disease; acute respiratory failure; respiratory distress syndrome; persistent pulmonary hypertension of the newborn.;

   Abstract : Pulmonary hypertension leading to hypoxemia is a potentially life-threatening condition in pediatric intensive care. Hypoxemia may also result from conditions not primarily related to pulmonary hypertension. READ MORE

7. 5. Breathing and phonation : effects of lung volume and breathing behaviour on voice function

   Author : Jenny Iwarsson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Abduction; Adduction; Breathing; Flow glottogram; Inhalation; Lung volume; Perceptual analysis; Phonation; Posture; Speech lung volume; Speech task; Subglottal pressure; Tracheal pull; Vertical laryngeal position; Vocal fold nodules; Voice source;

   Abstract : Respiration is believed to play a central role in voice function and is thus of relevance to the clinical care of the disordered voice. The overall aim of the present study was to experimentally investigate relationships between the respiratory and phonatory systems. READ MORE
