Breathing pattern during bronchial challenge in humans.
Increases in minute ventilation (V'E) have been observed during exacerbations of asthma and in response to administration of histamine. However, it is not yet clear how the breathing pattern is affected, and whether the increase in V'E is found in general. In the present study, the effects of inhalation of histamine on respiratory frequency (fR), tidal volume (VT), V'E, and on functional residu...
متن کاملLung volume measured during sequential swallowing in healthy young adults.
PURPOSE Outcomes from studying the coordinative relationship between respiratory and swallow subsystems are inconsistent for sequential swallows, and the lung volume at the initiation of sequential swallowing remains undefined. The first goal of this study was to quantify the lung volume at initiation of sequential swallowing ingestion cycles and to identify the respiratory pattern(s) surroundi...
متن کاملTime course of ozone-induced changes in breathing pattern in healthy exercising humans.
We examined the time course of O3-induced changes in breathing pattern in 97 healthy human subjects (70 men and 27 women). One- to five-minute averages of breathing frequency (f(B)) and minute ventilation (Ve) were used to generate plots of cumulative breaths and cumulative exposure volume vs. time and cumulative exposure volume vs. cumulative breaths. Analysis revealed a three-phase response; ...
متن کاملBreathing and swallowing dynamics across the adult lifespan.
BACKGROUND Aberrations in the physiologic components of normal oropharyngeal swallowing have been linked to aspiration events and to predisposition to aspiration pneumonia, a common, deadly disease in elderly persons. Studies have demonstrated a temporal, physiologic link between breathing and the principal physiologic swallowing components involved in airway protection during swallowing. We de...
متن کاملInfluence of awareness of the recording of breathing on respiratory pattern in healthy humans.
This study was designed to test whether awareness of the measurement of breathing influences the breathing pattern in healthy subjects under routine laboratory conditions. Seventy four subjects (40 females and 34 males), aged 21-63 yrs, were studied under three different conditions whilst their breathing was being recorded for 5 min by means of inductance plethysmography (Respitrace): 1) subjec...
