WebRespiratory motor output was assessed by total pressure generated by the respiratory muscles (Pmus), computed from oesophageal pressure (Poes). In Protocol A, alteration in … WebJan 1, 2003 · Experiences may alter respiratory mechanics or gas exchange, thereby altering ventilation but obscuring the underlying change in (neural) respiratory motor output. For example, neonatal hypoxia causes persistent changes in respiratory mechanics, diminishing future hypoxic ventilatory responses ( 182-184 ), but without changing integrated neural …
Effects of stabilizing or increasing respiratory motor outputs on ...
WebSep 1, 2002 · Spontaneous respiratory motor output was recorded from cranial nerve 7 at control bath pH (7.8) and hypercapnic bath pH (7.4) as bath concentrations of a 5HT1A receptor agonist were steadily ... WebSep 7, 2004 · 1 . To determine the magnitude and time course of changes in respiratory motor output caused by non-chemical influences, six sleeping subjects underwent assist-control mechanical ventilation (ACMV) at increased tidal volume (V T).During ACMV, end-tidal P CO2 (P ET,CO2) was either held at normocapnic levels (P ET,CO2, 0·6-1·1 mmHg > … low loader prime mover trucks
Role of Respiratory Motor Output in Within-Breath …
Webrespiratory motor output. Furthermore, qualitative changes in intrathoracic pressure were without influence on the respiratory modulation of MSNA. In all conditions, within-breath changes in MSNA were inversely related to small changes in diastolic pressure (1 to 3 mm Hg), suggesting that respiratory rhythmicity in MSNA was secondary to WebMar 1, 2001 · Although age affects the neural control of breathing, such as alterations in hypoxic or hypercapnic responses (Fukuda, 1991, 1992), little is known concerning the specific underlying neural mechanisms affected by age.In this study, we investigated the effects of age on a serotonin-dependent respiratory memory: long term facilitation (LTF) … WebJan 23, 2013 · stabilizing respiratory drive or reducing chemosensitivity re-duces airway resistance and/or relieves airway obstruction in some sleep apnea patients (5, 15, 28, 69). … jasper williams jr wife
