We used spectral analysis and event-triggered averaging to determine the effects of chemical inactivation of the medullary lateral tegmental field (LTF) on 1) the relationship of intratracheal pressure (ITP, an index of vagal lung inflation afferent activity) to sympathetic nerve discharge (SND) and phrenic nerve activity (PNA) and 2) central respiratory rate in paralyzed, artificially ventilat...

background: in recent years, various noninvasive respiratory support (nrs) of ventilation has been provided more in neonates. the aim of this study was to compare the effect of hfnc with ncpap in post-extubation of preterm infants with rds after insure method (intubation, surfactant, extubation). methods: a total of 54 preterm infants with rds (respiratory distress syndrome) were enrolled in th...

The correlation between respiratory rate and body mass in the first three years of life was examined in 635 infants and children, aged between 15 days and 3.5 years. Assessments were made during quiet sleep and when awake and calm. Their body weight (2.8-20.5 kg) was measured at the same time. Respiratory rate decreased exponentially with increasing body weight. After log transformation of the ...

BACKGROUND One of the most important limitations of standard pulse oximeters is the inability to detect changes in respiratory rate until oxygenation is affected. This study sought to determine if analysis of the plethysmogram by wavelet transforms would enable the determination of changes in respiratory rate at an earlier stage. METHODS Ten healthy adult volunteers were monitored, breathing ...
