introduction respiratory distress syndrome (rds) is a current cause of morbidity in premature infants resulted from surfactant deficiency. the primary aim of this randomized study was to describe the feasibility of early administration of surfactant via a thin catheter during spontaneous breathing (tec) and compare its outcomes with the insure (intubate, surfactant, extubate) procedure material...

Autonomic nervous system control in subjects with vasovagal syncope is controversial. In the present study, we used short-term spectral analysis to evaluate autonomic control in subjects with recurrent vasovagal syncope. We assessed the ability of spectral indices of HR (heart rate) variability to predict tilt-test responses. A series of 47 outpatients with recurrent vasovagal syncope and with ...

Introduction Currently, WH MRCA [1] [2] studies are usually performed during free breathing while monitoring the position of the diaphragm. However, since the scan time is rather long, the patient's breathing pattern may change during scanning and scanning sometimes cannot be completed. An abdominal band can be applied to the patient in order to limit movement of the diaphragm, but this cannot ...

BACKGROUND The predictive value of heart rate variability (HRV) in chronic heart failure (CHF) has never been tested in a comprehensive multivariate model using short-term laboratory recordings designed to avoid the confounding effects of respiration and behavioral factors. METHODS AND RESULTS A multivariate survival model for the identification of sudden (presumably arrhythmic) death was dev...

OBJECTIVE To evaluate the safety and efficacy of temperature-controlled radiofrequency tonsil reduction in the treatment of children with a sleep-related breathing disorder associated with tonsillar obstructive hypertrophy. DESIGN Prospective, nonrandomized, case series feasibility study of children meeting the criteria for tonsillectomy or adenotonsillectomy for the treatment of an obstructi...

introduction: adenotonsillar hypertrophy (ah) is considered the most common cause of upper respiratory tract obstruction among children. it results in a spectrum of symptoms from mouth breathing, nasal obstruction, hyponasal speech, snoring, and obstructive sleep apnea (osa) to growth failure and cardiovascular morbidity. adenotonsillectomy is a typical strategy for patients with ah, but may le...

F1 Central Neural Substrates of Cardiorespiratory Control During Slow Breathing and Hypoxic Challenge Alessia Nicotra, MD; Hugo Critchley, MD; Patrizia Chiesa, MD; Yoko Nagai, MD; Marcus Gray, MD; Ludovico Minati, MD; Luciano Bernardi, MD Controlled slow breathing (at 6/min) can have beneficial effects on cardiovascular function, including responses to hypoxia. We tested neural substrates of ca...

Human speech production requires the dynamic regulation of air through the vocal system. While virtual character systems commonly are capable of speech output, they rarely take breathing during speaking – speech breathing – into account. We believe that integrating dynamic speech breathing systems in virtual characters can significantly contribute to augmenting their realism. Here, we present a...

purpose: patterned breathing allows standardized serial measurements of heart rate variability and baroreflex indices. the slow breathing augments these parameters, and regular exercises, including yoga breathing practices with even respiratory rates have long-term beneficial effects in cardiovascular diseases. the role of temporization of breathing phases, i.e. the ratio of expiration to inspi...
