Effects of pulse lung inflation on chest wall expiratory motor activity.
The effects of pulse lung inflation (LI) on expiratory muscle activity and phase duration (Te) were determined in anesthetized, spontaneously breathing dogs (n = 20). A volume syringe was used to inflate the lungs at various times during the expiratory phase. The magnitude of lung volume was assessed by the corresponding change in airway pressure (Paw; range 2-20 cmH(2)O). Electromyographic (EM...

J Appl Physiol 101: 628–634, 2006; doi:10.1152/japplphysiol.00155.2006.— Historical aspects of respiratory reflexes from the lungs and airways are reviewed, up until about 10 yr ago. For most of the 19th century, the possible reflex inputs into the “respiratory center,” the position of which had been identified, were...

First published May 4, 2006; doi:10.1152/japplphysiol.00161.2006.— Mouse model research is proliferating because of its readiness for genetic manipulation. Little is known about pulmonary vagal afferents in mice, however. The purpose of this study was to d...
متن کاملTranspulmonary and pleural pressure in a respiratory system model with an elastic recoiling lung and an expanding chest wall
BACKGROUND We have shown in acute lung injury patients that lung elastance can be determined by a positive end-expiratory pressure (PEEP) step procedure and proposed that this is explained by the spring-out force of the rib cage off-loading the chest wall from the lung at end-expiration. The aim of this study was to investigate the effect of the expanding chest wall on pleural pressure during P...
متن کاملSignificance of pulmonary vagal afferents for respiratory muscle activity in the cat.
The influence of vagal stretch receptor afferents on respiratory motor-output and respiratory changes in esophageal pressure (DeltaP(es)) was studied in anaesthetized cats. Tracheal occlusions and lung inflations were performed during hyperoxic normocapnia, during electrical stimulation of one carotid sinus nerve (CSN) or the intracranial medullary chemosensitivity (MCS), during hypercapnia or ...
