[Purpose] It is unclear whether diaphragmatic breathing (DB) results in lower respiratory muscle oxygen consumption during dynamic exercise. The purpose of this study was to compare oxygen consumption in the respiratory muscles (VO2rm) with thoracic breathing (TB) and with DB, in healthy males during hyperventilation. [Subjects and Methods] Ten healthy men participated in this study. The subjec...

The use of noninvasive techniques to measure respiratory muscle performance after different types of endurance exercise has not been entirely successful, as the results have not consistently indicated diminished performance for similar types of exercise. The aim of the present study was 1) to compare different, noninvasive methods to assess respiratory muscle performance before and after an exh...

Ventilatory data, including timing and partitioning of ventilation, were obtained from six subjects with advanced Duchenne muscular dystrophy, aged 16 to 22 years, during polysomnography on two consecutive nights; the subjects were randomized to breathing air or oxygen. Five of the six patients developed oxygen desaturation exceeding 5 percent during rapid eye movement (REM) sleep while breathi...

Resistive breathing (encountered in chronic obstructive pulmonary disease and asthma) results in cytokine upregulation and decreased nitric oxide (NO) levels in the strenuously contracting diaphragm. NO can regulate gene expression. We hypothesized that endogenously produced NO downregulates cytokine production triggered by strenuous diaphragmatic contraction. Wistar rats treated with vehicle, ...

This study explores the physiological correlates of a highly practiced Kundalini Yoga meditator. Thoracic and abdominal breathing patterns, heart rate (HR), occipital parietal electroencephalograph (EEG), skin conductance level (SCL), and blood volume pulse (BVP) were monitored during prebaseline, meditation, and postbaseline periods. Visual analyses of the data showed a decrease in respiration...

More than half of college students self-report some kind anxiety and depression. This study reports how a university course that incorporated structured self-experience practices may reduce symptoms self-reported associated with stress strain. Ninety-eight Junior Senior were enrolled in Holistic Health class focused on “whole-person” curriculum included the exploration psychobiology stress, rol...

A 78-year-old female patient was admitted to the emergency department with severe abdominal pain and respiratory distress. In Computer Tomography (CT) examination of patient; It observed that there a hernia in left leaf diaphragm stomach, spleen intestines were protruding pleural space up clavicle. patient's anamnesis; breathing difficulty has been going on for many years increased recent days ...

Background: The diaphragm is a dome-shaped respiratory muscle located near the lower ribs, exact location below chest. Diaphragmatic rupture medical condition caused by blunt or penetrating trauma, which often leads to herniation of abdominal viscera into thoracic cavity.
 Case: We presented case in 39-year-old man complained left chest pain and radiated his back, after involed traffic acc...

INTRODUCTION Partial assist ventilation reduces work of breathing in patients with bronchospasm; however, it is not clear which components of the ventilatory cycle contribute to this process. Theoretically, expiratory positive airway pressure (EPAP), by reducing expiratory breaking, may be as important as inspiratory positive airway pressure (IPAP) in reducing work of breathing during acute bro...
