A Clinical Study Aiming to Validate the Equipment: VoluSense Pediatrics (VSP)
Validation of VoluSense Pediatrics, a New Method of Infant Spirometry Based on Electromagnetic Inductance Plethysmography
Study Overview
Detailed Description
All infants will be assessed at the pediatric department at Haukeland University Hospital, and all data obtained by the same two investigators (Bentsen and Olsen). The infants will be dressed in the appropriate-sized vest selected according to the length from the armpit to the hip of the child. Care will be taken to ensure that the vest fits snugly around the torso and that the width of the copper wire zig-zag coveres the entire thorax and abdomen including the pubic region. The vest will be applied directly to the skin; neither body nor diaper will be worn underneath. The infants will then be fed before they will be placed supine in a cot and encouraged to sleep. No sedation will be used. Once the infant has fallen asleep, data will be collected with VSP for 2-3 minutes before the Exhalyzer D® neonatal facemask connected in series with the ultrasonic flow sensor will be placed gently, but firmly over the infant's mouth and nose, ensuring a good seal. Once the facemask is in place, a marker will be inserted in the VSP recording. The Exhalyzer D® measurement will be started about thirty seconds after the facemask has been put on, to allow adaptation to the facemask. Simultaneous recording using both devices will then be done for about 1 minute before the mask will be removed. New markers will be inserted in the VSP recording as the Exhalyzer D® measurement is started and stopped facilitating analysis of the same breathing cycles.
Data will be analysed and graphs will be created with SPSS version 22 (IBM SPSS Statistics, New York, US) and MedCalc version 13.1 (MedCalc Software, Mariakerke, Belgium). Bland-Altman plots will be used to visualize agreement between the two measurement techniques. For each pair of measurements, the pairwise mean of the breathing parameters will be plotted on the x-axis, and the pairwise difference expressed as a percentage of their mean value on the y-axis. The mean difference and the 95% limits of agreement and their confidence intervals will be represented by horizontal lines in the graphs.

Cohorts and Interventions
Group / Cohort |
Intervention / Treatment |
---|---|
Infants (term borns and preterm borns)
Intervention: simultaneous lung function measurement using VoluSense Pediatrics and a mask-based method with an ultrasonic flowmeter (EcoMedics Exhalyzer)
|
The infants will be exposed to lung function measurements performed by a new metod (Volusense Pediatrics) and a validated method (EcoMedics Exhalyzer D).
The two Methods will be compared.
This is not an intervential study, but a study aiming to validate a New Method versus an old method
