Respiratory Cycle Related EEG Changes: Modified Respiratory Cycle Segmentation
Biomedical Signal Processing and Control, 2013 Respiratory cycle related EEG change (RCREC) is characterized by significant relative EEG power changes within different stages of respiration during sleep. RCREC has been demonstrated to predict sleepiness in patients with obstructive sleep apnoea and is hypothesized to represent microarousals.

Analyzing Seismocardiogram Cycles to Identify the Respiratory Phases
IEEE Transactions on Biomedical Engineering, 2017the objective of this study was to develop a method to identify respiratory phases (i.e., inhale or exhale) of seismocardiogram (SCG) cycles. An SCG signal is obtained by placing an accelerometer on the sternum to capture cardiac vibrations.SCGs from 19 healthy subjects were collected, preprocessed, segmented, and labeled. To extract the most important

Effect of the Oestral Cycle on Respiratory Mechanics in the Rat
Acta Physiologica, 2007AbstractAim: To assess the effect of the oestral cycle on the respiratory mechanics of the rat.Methods: We measured the main mechanical respiratory parameters, namely respiratory system and lung resistances and compliances, by the end‐inflation occlusion method on two populations of female rats, during proestrous–oestrous and metaoestrous–diestrous ...

Menstrual Cycle and Respiratory Symptoms in a General Nordic-Baltic Population.
American Journal of Respiratory and Critical Care Medicine, 2013 RATIONALE: There is little knowledge of variations in respiratory symptoms during the menstrual cycle in a general population, and no investigation of potential modifying factors.

Control of the Respiratory Cycle in Conscious Humans
Journal of Applied Physiology, 1995Rafferty, G. F., and W. N. Gardner. Control of the respiratory cycle in conscious humans. J. Appl. Physiol. 81(4): 1744–1753, 1996.—We studied in conscious humans the relative strength of mechanisms controlling timing and drive components of the respiratory cycle around their resting set points.

Changes in the respiratory cycle associated with sleep
Respiration Physiology, 1976Abstract The respiratory cycle of unmedicated, unrestrained cats was compared in 3 conditions: awake, slow-wave sleep (SWS) and rapid eye movement sleep (REMS). Average inspiratory and expiratory flow rates were similar in the three. Tidal volume and the durations of both respiratory phases increased approximately 30% during SWS and returned to the ...

Dynamic Imaging of the Respiratory Cycle with 81mKr
Chest, 1982To define the regional ventilation of the human lung, subjects were monitored with a gamma camera, while breathing air labeled with radioactive 81mKr which is being continuously eluted from a generator. The information observed is displayed as a reiterated multiframe moving picture. This is accomplished by storing the information from multiple breaths,

Alteration of respiratory cycle timing by propranolol
Toxicology and Applied Pharmacology, 1989The present study was undertaken to explore the effect of propranolol on respiratory cycle timing and breathing pattern using mice and guinea pigs. Propranolol was administered via aerosol or via injection. Mice exposed to propranolol aerosols exhibited a breathing pattern that was characterized by a pause between breaths. The length of such pauses (TP)
