Voluntary moderate deep inspiration breath hold (vmDIBH) in left-sided breast cancer radiotherapy reduces cardiac dose. The aim of this study was to investigate heart position variability in vmDIBH using CBCT and to compare this variability with differences in heart position between vmDIBH and free breathing (FB). For 50 patients initial heart position with respect to the field edge (HP-FE) was measured on a vmDIBH planning CT scan. Breath-hold was monitored using an in-house developed vertical plastic stick...

PURPOSE: Sedation in extracorporeal membrane oxygenation (ECMO) is challenging. Patients require deep sedation because of extremely high respiratory rates and increased work of breathing ("Drowning Syndrome") resulting in altered intra-thoracic pressure and reduced pump flow associated with hemodynamic compromise and decreased oxygenation. However, deep sedation impedes essential active rehabilitation with physical therapy. METHODS: We reviewed data on 3 ECMO patients for whom we used a novel approach to replace continuous drips with periodic sedation/paralysis...

PURPOSE: Dosimetric studies have suggested greater cardiopulmonary sparing with protons over photons for left-sided postmastectomy radiation therapy (PMRT). Modern techniques such as deep inspiration breath hold (DIBH) can help spare the heart. This analysis compares photon and proton delivery with and without DIBH. METHODS AND MATERIALS: Ten women with left breast cancer referred for PMRT on a prospective clinical trial with unfavorable cardiac anatomy underwent free breathing (FB) and DIBH computed tomography simulation...

BACKGROUND: It has been reported that deep breathing could reduce blood pressures (BP) in general. It is also known that BP is decreased during inhalation and increased during exhalation. Therefore, the measured BPs could be potentially different during deep breathing with different lengths of inhalation and exhalation. This study aimed to quantitatively investigate the effect of different respiratory patterns on BPs. METHODS: Forty healthy subjects (20 males and 20 females, aged from 18 to 60 years) were recruited...

A child suspected of exercise-induced laryngeal obstruction and asthma is examined by laryngoscopy and respiratory resistance (Rrs) after exercise challenge. Immediately at exercise cessation, the visualized adduction of the larynx in inspiration is reflected in a paroxystic increase in Rrs. While normal breathing has apparently resumed later on during recovery from exercise, the pattern of Rrs in inspiration is observed to reoccur following a deep breath or swallowing. The procedure may thus help diagnosing the site of exercise-induced obstruction when laryngoscopy is not available and identify re-inducers of laryngeal dysfunction...

In patients with muscular dystrophies both muscle length tension relationship changes and muscle elasticity and plasticity are decreased, resulting in impaired inspiratory muscle function and decreased vital capacity. Furthermore, the loss of deep breathing further increases the risk of alveolar collapse, hypoventilation and atelectasias. In this case report, a stable improvement of vital capacity after treatment with mounthpiece ventilation (MPV), was observed, suggesting that not invasive ventilation (NIV) might help to maintai lung and chest wall compliance, prevent hypoventilation and atelectasias which in turn may slow down the development of the restrictive respiratory pattern...

Idiopathic pulmonary fibrosis (IPF) is one of the most common idiopathic interstitial pneumonia. The main symptoms for IPF are dry cough and exertional shortness of breath, which is worsen gradually with the development of pulmonary fibrosis. Patients with IPF often suffer from sleep disordered breathing (SDB). Sleep architecture for these patients including the sleep efficiency, deep sleep, rapid eye movement sleep and arousal index, are changed, which seriously affects the quality of life. In the absence of effective therapies, optimizing the quality of life may become a major therapeutic target for IPF...
