متن کاملCentral sleep apnoea.
Central sleep apnoea (CSA) is characterized by the cessation of breathing during sleep due to absent ventilatory drive and may be associated with symptoms of insomnia, excessive daytime sleepiness or frequent arousals. Central apnoeas occur through two pathophysiologic patterns, either post- hyperventilation or post-hypoventilation. The prevalence of CSA is dependent on the population being stu...
متن کاملAn explanation for failure of impedance apnoea alarm systems.
24-hour recordings of the ECG and respiration, the latter from an impedance technique, have shown a phenomenon which could account for hitherto unexplained failures of impedance apnoea alarm systems. Whenever apnoea is accompanied by bradycardia there is a pronounced increase in the amplitude of the cardiac impulse on the respiration carrier. This imitates the respiration signal and prevents th...
متن کاملHome monitoring for central apnoea.
Between July 1978 and December 1981, 64 infants thought to be at increased risk from sudden infant death syndrome (SIDS) were monitored at home for central apnoea. Twenty four of the infants had had a 'near miss' episode at age, median (range), 6 (1 to 33) weeks, and of these infants 22 had had 335 alarms for apnoea by age 6 months. Stimulation by shaking was carried out on 38 occasions and bag...
متن کاملUniversal Central Extension of Current Superalgebras
Representation as well as central extension are two of the most important concepts in the theory of Lie (super)algebras. Apart from the interest of mathematicians, the attention of physicist are also drawn to these two subjects because of the significant amount of their applications in Physics. In fact for physicists, the study of projective representations of Lie (super)algebras are very impo...
