Pediatric asthma lacks sensitive objective measures for asthma monitoring. The forced oscillation technique (FOT) offers strong feasibility across the paediatric age range but relationships between FOT parameter day-to-day variability and paediatric asthma severity and control are unknown.
Conclusions: Increased day-to-day FOT variability exists in asthmatic school-aged children. Day-to-day Rrs variability was associated with asthma severity and with asthma control. FOT may be useful objective monitoring tool in paediatric asthma and warrants further study.
