Induced bronchoconstriction in normal subjects can be transiently reversed by a deep breath (airway hysteresis). The mechanisms of airway hysteresis are not fully understood. The aim of these studies was to determine whether the nature of the deep breath (slow or fast inspiration, five or 10 second breath hold) affects the resultant bronchodilatation. Bronchoconstriction was induced in 10 norma...

OBJECTIVE While there is recent interest in using repeated deep inspiratory breath-holds, or prolonged single breath-holds, to improve radiotherapy delivery, breath-holding has risks. There are no published guidelines for monitoring patient safety, and there is little clinical awareness of the pronounced blood pressure rise and the potential for gradual asphyxia that occur during breath-holding...

We wished to find out if a deep inspiration had any influence on subsequent breathing which was mediated by neural rather than chemical stimuli. We therefore compared the effect on ventilation of a deep isocapnic breath with that of a similar breath containing 6% CO2, and with the effect of two successive tidal volume breaths of 6% CO2. We studied five normal subjects, each of whom repeated the...
