PURPOSE We evaluated the influence of prior maximal exhalation on preoxygenation in 15 adult volunteers using tidal volume breathing (TVB) for five minutes and deep breathing (DB) for two minutes with and without prior maximal exhalation. METHODS Inspired and end-tidal oxygen, nitrogen and carbon dioxide were monitored continuously and recorded during room air breathing and at 30-sec interval...

In this paper we present the design and validation of a novel fully embroidered meander dipole antenna-based sensor integrated into commercially available T-shirt for real-time breathing monitoring using technique based on chest well movement analysis. The is made silver-coated nylon thread. proposed antenna-sensor cotton placed middle human chest. was designed to operate at 2.4 GHz. sensing me...

The concept that interactions between the mind and body influence physical health has existed for a long time (1). These interactions form the basis for mind–body practices. They are considered bi-directional (“top-down” and “bottom-up”), with connections between the brain and peripheral tissues (2). Top-down mechanisms are initiated by the cerebral cortex and include clinical hypnosis, imagery...

aim and background: enuresis is known as one of the most common disorders in childhood. snoring at night and obstructive sleep apnea have been considered as probable causes, at least in some cases. thus, the importance of a breathing exercise to reduce bedwetting in children with nocturnal snoring should be noted. method and materials: this study is an experimental survey with control group. th...

Introduction: The rapid heart rates and deep breathing encountered during exercise or dobutamine stress MRI make it difficult to achieve the necessary spatial resolution, temporal resolution, and image quality with real-time cine techniques. Parallel imaging has enabled improved temporal resolution, but at the cost of increased artifact and noise. Temporal resolution can be further improved by ...

Recovery after surgical reconstruction of a brachial plexus injury using nerve grafting and nerve transfer procedures is a function of peripheral nerve regeneration and cerebral reorganization. A 15-year-old boy, with traumatic avulsion of nerve roots C5-C7 and a non-rupture of C8-T1, was operated 3 weeks after the injury with nerve transfers: (a) terminal part of the accessory nerve to the sup...

OBJECTIVE To investigate the applicability of ultrasound imaging of the diaphragm in interstitial lung disease (ILD). METHODS Using ultrasound, we compared ILD patients and healthy volunteers (controls) in terms of diaphragmatic mobility during quiet and deep breathing; diaphragm thickness at functional residual capacity (FRC) and at total lung capacity (TLC); and the thickening fraction (TF,...

Airway hyperresponsiveness is the excessive narrowing of the airway lumen caused by stimuli that would cause little or no narrowing in the normal individual. It is one of the cardinal features of asthma but remains largely unexplained. Sometimes, though, clues to the greatest mysteries are right in front of us but we do not see them, and the role of breathing in airway hyperresponsiveness may b...

UNLABELLED Nebulised drugs are very useful in COPD exacerbations. The most frequently used propellant is compressed air, which is commonly administered together with nasal oxygen in those patients with respiratory failure. The purpose of this approach is to avoid the risks inherent in breathing high inspiratory oxygen fractions (FIO(2)). AIM To analyze the actual FIO(2) obtained with such a c...
