Ventilation (VE) rises throughout 40 min of constant elevated end-tidal PCO2 without reaching steady state (S. Khamnei and P. A. Robbins. Respir. Physiol. 81: 117-134, 1990). The present study investigates 8 h of euoxic hypercapnia to determine whether VE reaches steady state within this time. Two protocols were employed: 1) 8-h euoxic hypercapnia (end-tidal PCO2 = 6.5 Torr above prestudy value, end-tidal PO2 = 100 Torr) followed by 8-h poikilocapnic euoxia; and 2) control, where the inspired…

Ventilatory effects of 8 h of isocapnic hypoxia with and without beta-blockade in humans.

Evidence is not provided that changes in sympathetic activity acting via beta-receptors play a role in the mediation of ventilatory changes observed during 8 h of isocapnic hypoxia, and beta-Blockade did not significantly alter either the rise in VE or the changes observed in the acute hypoxicventilatory response and residual VE in hyperoxia over that period.

Respiratory effects in humans of a 5-day elevation of end-tidal PCO2 by 8 Torr.

The results do not support the hypothesis that the ventilatory adaptation to chronic hypercapnia would be much greater with constant elevation of alveolar PCO2 than with constant Elevated end-tidalPCO2, as has been used in previous studies and in which the feedback loop between ventilation and alveolars is left intact.

Identification of fast and slow ventilatory responses to carbon dioxide under hypoxic and hyperoxic conditions in humans

It is concluded that the rapid and slow components of the ventilatory response to CO2 can be separately identified, and that a rapid component persists under conditions of hyperoxia.

Effects of subanaesthetic sevoflurane on ventilation. 1: Response to acute and sustained hypercapnia in humans.

It is suggested that 0.1 minimum alveolar concentration of sevoflurane does not significantly affect the acute ventilatory response to hypercapnia and does not modify the progressive changes in ventilation and pattern of breathing that occur with sustainedhypercapnia.

Effect of work intensity on time delay in mediation of ventilation by arterial carbon dioxide during recovery from impulse exercise.

Results indicate that PaCO(2 pre) drives V(.)E with a time delay and that higher work intensity induces a shorter time delay.

A steady-state modeling approach is used to describe the effects of changes in acid-base balance on the chemoreflex control of breathing, and demonstrates that the relationship between Pco(2) and [H(+)] should not be neglected when modeling the che more Flexibility Control of breathing.

Selected contribution: Ventilatory response to CO2 in high-altitude natives and patients with chronic mountain sickness.

Values for the slow (central) time constant were significantly greater for HA and CMS subjects than for SL subjects, and the total and central chemoreflex sensitivity to CO(2) in euoxia was higher in HA subjects than in SL subjects.

Effect of low dose inhaled anaesthetic agents on the ventilatory response to carbon dioxide in humans: a quantitative review

The results suggest that the hypercapnic response is more resistant to the effects of anaesthetics than the hypoxic ventilatory response, and possible ways in which subject arousal might interact in the brain with the chemoreflexes.

The ventilatory response to hypoxia in mammals: mechanisms, measurement, and analysis.

The mechanisms underlying the HVR and its adaptations to chronic changes in ambient oxygen concentration are discussed, with emphasis on the carotid bodies that contain oxygen sensors and initiate the response, and on the contribution of central neurotransmitters and brain stem regions.

Plasticity in Respiratory Motor Control Selected Contribution : Ventilatory response to CO 2 in high-altitude natives and patients with chronic mountain sickness

The ventilatory responses to CO2 of high-altitude natives and patients with chronic mountain sickness were studied and compared with sea-level natives living at SL and values for the slow time constant were significantly greater for HA and CMS subjects than for SL subjects.

Step changes in end-tidal CO2: methods and implications.

The delay in the ventilation response after the change in end-tidal CO2 is less in hypoxia than in normoxia and reflects the action of a transport delay and that of a virtual delay.
