The retrotrapezoid/parafacial respiratory group (RTN/pFRG) located ventral to the facial nucleus plays a key role in regulating breathing, especially enhanced expiratory activity during hypercapnic conditions. To clarify the roles of the RTN/pFRG region in evoking coughing, during which reflexive enhanced expiration is produced, and in swallowing, during which the expiratory activity is consist...
1. The relationship between blood pressure and heart rate responses to coughing was investigated in 10 healthy subjects in three body positions and compared with the circulatory responses to commonly used autonomic function tests: forced breathing, standing up and the Valsalva manoeuvre. 2. We observed a concomitant intra-cough increase in supine heart rate and blood pressure and a sustained po...
BACKGROUND To prepare for a possible influenza pandemic, a better understanding of the potential for the airborne transmission of influenza from person to person is needed. OBJECTIVES The objective of this study was to directly compare the generation of aerosol particles containing viable influenza virus during coughs and exhalations. METHODS Sixty-one adult volunteer outpatients with influ...
Abstract
Paralysis of the respiratory muscles in people with tetraplegia affects their ability to breathe and contributes to respiratory complications. Surface functional electrical stimulation (FES) of abdominal wall muscles can be used to increase tidal volume (V_{T}) and improve cough peak flow (CPF) in tetraplegic subjects who are able to breathe spontaneously. This study aims to evaluate the feasib...
Precice information on the treatment of bronchial asthma in Persia up to 9th and 10th century is not available. However according to some old religious books like Yasna and Vendidad, the “Haoma” had been used in the treatment of perspiration disorders and its extract had been advised by Zoraster as sacred water.

Background and purpose: Fluctuations in the heart rate can be affected by many factors such as breathing. The amplitude of heart rate variability during inhalation and exhalation provides a quantitative measure that puts the estimate of cardiac vagal function which is considered. The aim of this study was to investigate the effect of a single dose of hyoscine-N-butylbromide (hyoscine) on the am...
Natural human exhalation flows such as coughing, sneezing and breathing can be considered as 'jet-like' airflows in the sense that they are produced from a single source in a single exhalation effort, with a relatively symmetrical, conical geometry. Although coughing and sneezing have garnered much attention as potential, explosive sources of infectious aerosols, these are relatively rare event...
