[Purpose] Physical examinations for chest movements by inspection and palpation are poorly reproducible. This study aimed to investigate the inter-rater reliability of a new breathing movement scale for patients with respiratory diseases, in clinical practice. [Subjects and Methods] Twenty-six patients with respiratory diseases were enrolled. BMS measurements were obtained during quiet breathin...

Decompression sickness (DCS) after air diving has been treated with success by means of combined normobaric oxygen breathing and intravascular perfluorocarbon (PFC) emulsions causing increased survival rate and faster bubble clearance from the intravascular compartment. The beneficial PFC effect has been explained by the increased transport capacity of oxygen and inert gases in blood. However, ...

OBJECTIVES Konstantin Buteyko, M.D., Ph.D., claimed that breath holding time (BHT) can be used to detect chronic hyperventilation and that BHT predicts alveolar CO(2) (Pa(CO(2))) according to his patented mathematical formula. The Buteyko Breathing Technique (BBT) is believed to correct chronic hyperventilation as evidenced by increased BHT. In this study, we test Buteyko's claims and explore t...

BACKGROUND The use of breathing exercises with positive-pressure devices during hospitalization aims to prevent the development of nosocomial pulmonary complications or to facilitate recovery from pulmonary conditions already present. Although this type of intervention has potential benefits and theoretical advantages over more conventional respiratory physiotherapy techniques, the literature o...

STUDY OBJECTIVE To assess abnormalities in thoracoabdominal pattern of breathing (TAPB) in neuromuscular disorders during spontaneous breathing, intermittent positive pressure ventilation (IPPV) with and without abdominal (AB) binder, and immediately after IPPV. DESIGN Repeated measures design: Pre-IPPV spontaneous breathing, IPPV, IPPV with AB binder, and post-IPPV spontaneous breathing. In ...

In Brief Objective: To evaluate the immediate effects of positive expiratory pressure therapy on oxygen saturation and ventilation after abdominal surgery. Background: Positive to treat postoperative hypoxia is widespread, despite a lack evidence effect. Methods: This randomized, sham-controlled, crossover trial investigated adults 1–2 days surgery at Umeå University Hospital, Sweden. The inter...

CT perfusion imaging is used for the follow-up of abdominal tumors. A specificity of our work is that patients are breathing freely during image acquisition (5 minutes). We propose an automatic 3D image registration to compensate respiratory motion. The registration is computed in two main steps: global translation in the z-direction and 3D multiresolution blockmatching. Within this algorithm, ...

BACKGROUND It has been recently shown that, when breathing at rest, many patients with severe chronic obstructive pulmonary disease (COPD) contract abdominal muscles during expiration, and that this contraction is an important determinant of positive end expiratory alveolar pressure (PEEPi). In this study the effects of acute bronchoconstriction on abdominal muscle recruitment in patients with ...

PURPOSE Respiratory motion causes substantial artifacts in reconstructed PET images when using helical CT as the attenuation map in PET/CT imaging. In this study, we aimed to reduce the respiratory artifacts in PET/CT images of patients with lung tumors using an abdominal compression device. METHODS Twelve patients with lung cancer located in the middle or lower lobe of the lung were recruite...

The use of a corrective orthopaedic brace is an established form of management for patients with progressive idiopathic scoliosis. Thirteen patients with mild idiopathic scoliosis were studied with and without the corrective brace applied. Lung volumes and the pattern of chest wall and abdominal movement were measured during quiet breathing. Transdiaphragmatic pressures were measured in six of ...
